Arbitrary code execution on IBM Power Systems host is achievable by any attacker who already holds service account or root access to the BMC or FSP management controller. The vulnerability resides in the interface layer between the BMC/FSP and the host, where missing authorization checks (CWE-862) allow an authenticated BMC-level principal to cross the trust boundary and execute code with full host-system privileges. All hosted logical partitions are consequently exposed, making this a critical lateral-movement and privilege-escalation path within IBM Power infrastructure. No public exploit code or CISA KEV listing has been identified at time of analysis.
Stack-based buffer overflow in IBM Power Firmware's host firmware configuration parser allows an attacker with service-level access to the BMC/FSP to supply specially crafted configuration data, triggering CWE-121 during the firmware boot stage and compromising the entire software stack loaded thereafter. Affected firmware spans multiple major release trains - FW1120, FW1110, FW1060, FW950, and OP940 - covering Power9 and Power HMC managed systems. No public exploit has been identified at the time of analysis, and a vendor patch is available from IBM.
Arbitrary code execution in IBM Power Firmware across multiple firmware branches (FW1120.00, FW1110.x, FW1060.x, FW950.x, OP940.x) stems from a CWE-787 out-of-bounds write in the service processor mailbox interface. An authenticated attacker with service-level access to the BMC/FSP can exploit this buffer overflow to cross the trust boundary from the management processor into the host firmware runtime, gaining full control over the managed Power system. No public exploit has been identified at time of analysis; IBM has released a patch per advisory 7283236.
Arbitrary code execution on IBM Power host systems is possible when an attacker with service processor access supplies a maliciously crafted firmware update image that bypasses boot-time image validation. Affected firmware versions span three release trains: FW1120.00, FW1110.00-FW1110.30, and FW1060.00-FW1060.80. Exploitation yields full confidentiality, integrity, and availability impact on the host, with scope change indicating the compromise extends beyond the service processor itself. No public exploit or CISA KEV listing is identified at this time.
Unauthenticated remote attackers can overwrite administrator email addresses and abuse IBM Langflow OSS as an outbound mail relay by exploiting a missing authentication control on the registration endpoint, affecting versions 1.0.0 through 1.10.0. The CVSS vector AV:N/AC:L/PR:N/UI:N confirms trivially reachable exploitation with no credentials or user interaction required. No public exploit or CISA KEV listing has been identified at time of analysis, though the low attack complexity makes this viable for opportunistic exploitation once the endpoint is discovered.
IBM AIX 7.2 and 7.3, along with IBM PowerVM VIOS 4.1, expose a time-of-check time-of-use (TOCTOU) race condition that local, unprivileged attackers can exploit to corrupt data integrity or crash the system. The flaw requires only local shell access with no privileges, making it exploitable by any local user account on affected POWER-architecture systems. No public exploit code or CISA KEV listing exists at time of analysis, though a vendor patch is available.
Uncontrolled resource consumption in IBM AIX 7.2, 7.3 and PowerVM VIOS 4.1 exposes these systems to remote denial-of-service attacks requiring no authentication or user interaction.

No public exploit has been identified at time of analysis, and IBM has released a patch via advisory 7283858.
Remote denial of service in IBM AIX 7.2/7.3 and PowerVM VIOS 4.1 is exploitable by unauthenticated attackers who send malformed client registration packets to the NIM (Network Installation Manager) server, triggering a classic buffer overflow that crashes the nimserver daemon. The CVSS 7.5 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) confirms low-complexity, network-accessible exploitation requiring no privileges, though impact is strictly limited to availability - no confidentiality or integrity exposure is present. IBM has released a patch via support advisory 7283858; no public exploit code has been identified and this vulnerability does not appear on the CISA KEV catalog at time of analysis.
Remote privilege escalation to root in IBM AIX 7.2 and 7.3 and IBM PowerVM VIOS 4.1 stems from an improper authentication weakness (CWE-287) that lets an unauthenticated network attacker bypass identity checks and obtain root-level control. The CVSS 9.8 rating reflects a network-reachable, low-complexity flaw requiring no privileges or user interaction, with full confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the severity and unauthenticated network vector make it a high-priority patching target for IBM Power estates.
Improper TLS certificate validation in the NIM (Network Installation Management) subsystem of IBM AIX 7.2, 7.3, and IBM PowerVM VIOS 4.1 enables remote attackers to gain unauthorized access to AIX systems by exploiting the failure to verify certificate authenticity during NIM communications. The CVSS 8.1 High score reflects high confidentiality and integrity impact across a network-exploitable path with low complexity and no user interaction required. No public exploit identified at time of analysis, but the authentication bypass classification of this flaw makes it a meaningful privilege escalation and lateral movement risk in IBM Power environments.
OS command injection in IBM AIX 7.2/7.3 and PowerVM VIOS 4.1 lets a remote authenticated attacker run arbitrary commands through the Network Installation Manager (NIM) component. Because NIM typically operates with high (often root-level) privilege and the CVSS scope is Changed, successful exploitation can compromise the underlying operating system with full confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis and it is not on CISA KEV, but the 9.9 base score and low attack complexity make it a high-priority patch for IBM Power estates.
Sensitive-key exposure in IBM AIX 7.2/7.3 and PowerVM VIOS 4.1 Network Installation Management (NIM) leaks intermediate certificate authority (CA) private keys inside a publicly downloadable update file, letting remote attackers forge trusted certificates and bypass security restrictions. Rated CVSS 9.1, the flaw impacts confidentiality and integrity (C:H/I:H) but not availability, and IBM has released a fix. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the ease of obtaining a live CA key makes this a high-priority credential-hygiene issue.
Unauthenticated remote file overwrite in IBM AIX 7.2/7.3 and PowerVM VIOS 4.1 is possible via the nimesis registration service, which fails to sanitize path traversal sequences in client-supplied input. An attacker with network access to the nimesis service can write arbitrary content to locations outside the intended directory, potentially overwriting sensitive system files such as cron jobs, init scripts, or authentication databases. No public exploit or active exploitation has been identified at time of analysis, though the CVSS vector (AV:N/AC:L/PR:N/UI:N) indicates this is straightforwardly exploitable without authentication.
Sensitive file disclosure in IBM Db2 Mirror for i versions 7.4, 7.5, and 7.6 is possible through a path traversal flaw (CWE-22) that allows attackers to escape a restricted directory boundary and read files outside the intended accessible path, resulting in high confidentiality impact. The CVE description attributes the exposure to a remote authenticated attacker, though this conflicts with the NVD-assigned CVSS vector - a discrepancy security teams must resolve before finalizing triage. A vendor patch is available via IBM Support advisory node/7283359; no public exploit code or CISA KEV listing has been identified at time of analysis.
Arbitrary file deletion in IBM Db2 Mirror for i versions 7.4, 7.5, and 7.6 is achievable by remote authenticated attackers holding only low-privileged credentials, exploiting a path traversal flaw that bypasses directory boundary enforcement to reference and delete files anywhere on the target filesystem. The CVSS 3.1 score of 8.1 reflects high integrity and availability impact with low attack complexity, though the EPSS score of 0.44% at the 37th percentile signals limited observed exploitation probability at time of analysis. No public exploit code has been identified and this vulnerability does not appear in the CISA KEV catalog.
Remote CL command execution in IBM Db2 Mirror for i 7.4, 7.5, and 7.6 lets a remote attacker run arbitrary Control Language commands on the IBM i host because special elements in a command are not properly neutralized (CWE-78).

The flaw carries a CVSS 9.8 rating with a network attack vector and no privileges or user interaction required, and IBM has published a fix. No public exploit code or active exploitation has been identified at time of analysis.
Authentication bypass in IBM Db2 Mirror for i (versions 7.4, 7.5, and 7.6) lets a remote, unauthenticated attacker read or modify sensitive information by exploiting improper validation of request URI path segments. Because the flaw is reachable over the network without credentials or user interaction, an attacker can defeat access controls on the replication/administration interface and reach protected functionality or data. No public exploit has been identified at time of analysis, but the maximal CVSS 9.8 rating and the low attack complexity make this a high-priority patching target.
Arbitrary file write via path traversal in IBM Db2 Mirror for i 7.4, 7.5, and 7.6 enables remote unauthenticated attackers to place files at any location on the underlying IBM i system. The CVSS vector (AV:N/AC:L/PR:N/UI:N/S:C/I:H) confirms network-reachable exploitation without authentication, with a scope change indicating impact beyond the Db2 Mirror application itself - reaching OS-level paths. No public exploit or KEV listing has been identified at time of analysis, and an EPSS of 0.59% (46th percentile) suggests low observed exploitation activity despite the high CVSS base score.
Uncontrolled recursion in IBM Db2 Mirror for i versions 7.4, 7.5, and 7.6 enables remote unauthenticated attackers to crash the service, resulting in a complete loss of availability. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms the flaw is exploitable over the network without credentials or user interaction, making it trivially reachable in any internet- or network-exposed deployment. No public exploit code or active exploitation (CISA KEV) has been identified at the time of analysis, but the low attack complexity elevates practical risk.
Arbitrary file write via path traversal in IBM Db2 Mirror for i versions 7.4, 7.5, and 7.6 exposes systems to unauthenticated remote exploitation. The flaw stems from improper pathname restriction (CWE-22), enabling an attacker to escape the intended directory sandbox and write files to arbitrary filesystem locations. No active exploitation has been confirmed in CISA KEV, and no public proof-of-concept exploit is known at the time of analysis, though the CVSS 8.2 High rating and network-accessible attack vector make this a credible priority for organizations running IBM i environments.

With a CVSS score of 8.8 and full confidentiality, integrity, and availability impact, exploitation could allow an attacker with only low-privilege credentials to read, modify, or disrupt mirrored database content. No public exploit code and no CISA KEV listing have been identified at time of analysis, though a vendor patch is available.
IBM Db2 Mirror for i versions 7.4, 7.5, and 7.6 exposes a network-accessible pathway through which an unauthenticated remote attacker can externally influence system configuration settings (CWE-15), enabling disclosure of sensitive information and - per the CVSS vector - potential integrity and availability compromise as well. The changed scope (S:C) in the CVSS vector indicates the vulnerability can propagate impact beyond the directly affected component, consistent with how mirror configuration alterations can affect the paired IBM i high-availability node. A vendor-released patch is available via IBM Support; no public exploit code exists and the vulnerability is not listed in the CISA KEV catalog at time of analysis.
Account takeover in IBM Langflow OSS versions 1.0.0 through 1.9.6 is possible because the platform fails to limit repeated failed authentication attempts (CWE-307), letting remote attackers brute-force or credential-stuff their way into user accounts. IBM (the reporting vendor) rates it CVSS 9.1 with high confidentiality and integrity impact, reflecting full compromise of a targeted account. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the missing lockout control is trivial to abuse against weak or reused credentials.
Stack-based buffer overflow in the Native IBM i JSSE (Java Secure Socket Extension) provider enables local authenticated attackers with low privileges to execute arbitrary code or crash the JVM process on IBM i versions 7.3 through 7.6. The flaw is triggered during TLS session establishment via improper bounds checking against a fixed-length stack buffer. No public exploit or active exploitation has been identified at time of analysis - EPSS stands at 0.22% (12th percentile) and SSVC exploitation status is 'none' - but a vendor patch is available and should be applied given the high-impact code execution potential.
Privilege escalation in IBM i versions 7.3 through 7.6 allows a local authenticated attacker to abuse improper authorization controls in the Navigator for i debugger component to access or manipulate sensitive system data, or create new profiles with elevated privileges. The vulnerability is classified under CWE-285 (Improper Authorization), indicating the debugger fails to enforce sufficient privilege checks before granting access to sensitive operations. No public exploit or CISA KEV listing exists at time of analysis, though SSVC assesses the technical impact as total should exploitation occur.
Privilege escalation in IBM i (7.3, 7.4, 7.5, 7.6) lets a remote, authenticated attacker gain elevated privileges by abusing improper validation of pointers read from Java-controlled addresses, giving full compromise of the affected component and a scope-changing impact beyond it. IBM assigned a critical CVSS 9.9 (S:C) despite requiring low privileges. No public exploit identified at time of analysis, and CISA SSVC records exploitation status as none, so this is a patch-worthy critical without evidence of active abuse yet.
Security-restriction bypass in IBM i (the operating system for IBM Power servers, formerly OS/400) versions 7.3 through 7.6 lets a remote attacker abuse improper validation of user-controlled addresses to elevate privileges and cross a security boundary. Vendor scoring rates this a maximum-severity, unauthenticated network flaw (CVSS 10.0, scope-changed), though there is no public exploit identified at time of analysis and EPSS exploitation probability is low (0.33%). IBM published a fix, and CISA's SSVC framework currently marks exploitation as 'none' with a 'total' technical impact.
Thread authority swap mismanagement in IBM i 7.3 through 7.6 enables a low-privileged local attacker to gain elevated system authorities, including potentially *ALLOBJ-equivalent access. The CVSS scope change (S:C) confirms that successful exploitation extends privilege impact beyond the attacker's own user profile, threatening the broader system partition. No public exploit or active CISA KEV listing exists at time of analysis; risk is driven by low attack complexity and the critical role IBM i plays in regulated enterprise environments.
Remote denial of service via stack-based buffer overflow affects IBM i versions 7.3 through 7.6, allowing unauthenticated network attackers to crash an affected service without any user interaction or elevated privileges.

No public exploit has been identified at time of analysis, and the CVE is not listed in the CISA KEV catalog; however, a vendor-released patch is available and should be applied promptly given the unauthenticated network vector.
Remote code execution in IBM Documentation Offline 1.0.0 through 1.4.1 allows an attacker to run arbitrary code by abusing improper control of file paths (CWE-73). The flaw is reachable over the network without authentication or user interaction per the vendor-assigned CVSS 9.8 vector, giving an attacker full read/write/execution impact on the host. No public exploit has been identified at time of analysis, and the issue is not listed in CISA KEV.
Remote code execution in IBM Documentation Offline 1.0.0 through 1.4.1 stems from improper neutralization of output written to logs (CWE-117), which a remote attacker can leverage to run arbitrary code with total impact to confidentiality, integrity, and availability. IBM has published a fix, and the vendor CVSS of 9.8 reflects an unauthenticated network-reachable vector; however, EPSS is low (0.27%, 19th percentile) and there is no public exploit identified at time of analysis, so exposure appears theoretical rather than active. Note a signal conflict: the root-cause weakness is log injection, yet the stated impact is code execution - the intermediate mechanism is not documented in the available data.
Path traversal in IBM Documentation Offline 1.0.0 through 1.4.1 enables unauthenticated remote attackers to read arbitrary files from the underlying server filesystem. The CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N vector confirms fully network-accessible exploitation with no privileges or user interaction required, resulting in high confidentiality impact but no integrity or availability loss. No public exploit has been identified at time of analysis, and the vulnerability is not listed in CISA KEV; however, the trivial attack complexity and zero-authentication requirement make exposed instances an immediate patching priority.
Authentication token validation flaws in IBM i 7.3 through 7.6 expose network-reachable systems to remote unauthenticated attackers capable of extracting sensitive information and performing limited unauthorized operations. The CWE-287 root cause (Improper Authentication) combined with a PR:N/AV:N CVSS vector confirms exploitation requires no credentials and no user interaction over the network. No active exploitation has been confirmed (not in CISA KEV), EPSS sits at 0.31% (23rd percentile), and SSVC marks exploitation status as 'none' - signals that collectively moderate urgency despite the 8.2 CVSS score.
Denial of service via buffer overflow in IBM i 7.3 through 7.6 exposes all supported release lines of IBM's midrange operating system to remote disruption.

A local attacker with low privileges can plant malicious content in this directory, which the application subsequently loads with higher-privilege context, achieving full code execution. No active exploitation is confirmed (not in CISA KEV), and the EPSS score of 0.11% (2nd percentile) reflects low observed exploitation pressure, though the SSVC technical impact rating is 'total', underscoring the severity if exploited.
Authentication bypass in IBM WebSphere Application Server Liberty (versions 17.0.0.3 through 26.0.0.8) allows remote attackers to circumvent authentication controls when the rtcomm-1.0 or rtcommGateway-1.0 feature is enabled, exposing protected real-time communication functions. The CVSS 3.1 base score is 9.4 (AV:N/AC:L/PR:N/UI:N/C:H/I:H/A:L), reflecting high confidentiality and integrity impact reachable over the network without credentials. A vendor patch is available; there is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV.
IBM Storage Scale GUI versions 5.2.3.0-5.2.3.8 and 6.0.0.0-6.0.1.0 ship with a hardcoded authentication token embedded in source code, granting any network-reachable attacker the ability to authenticate to the REST API and inter-node cluster communication channels without valid credentials. The static nature of the token means it is identical across every affected deployment, making a single disclosure universally exploitable against all unpatched instances. IBM has released a patch via advisory 7283308, and no public exploit or CISA KEV listing has been identified at time of analysis.
Remote denial-of-service in IBM i 7.3 through 7.6 allows unauthenticated network attackers to crash a host server by submitting malformed requests that trigger an out-of-bounds write (CWE-787) in the server's client data validation logic. The CVSS vector confirms no credentials or user interaction are required, making the attack straightforward to attempt against any network-reachable IBM i host server. No public exploit code has been identified at time of analysis, and IBM has released a patch via their support portal.
Remote code execution in IBM i 7.3 through 7.6 is achievable by any authenticated network attacker via an out-of-bounds write (buffer overflow) triggered over the network. The vulnerability requires only low-level credentials, making it accessible to any valid user account on an internet- or network-exposed IBM i system. No public exploit code or CISA KEV listing has been identified at time of analysis, but the vendor has confirmed the flaw and released a patch via IBM Support.
Remote code execution in IBM i (formerly OS/400) releases 7.3 through 7.6 stems from a buffer overflow (out-of-bounds write) that a remote, unauthenticated attacker can trigger to run arbitrary code on the host. IBM has published a fix, and while the CVSS base score is 9.8, there is no public exploit identified at time of analysis and EPSS estimates exploitation probability at only 0.37% (30th percentile). CISA's SSVC framing rates exploitation as none and the vulnerability as not automatable, tempering the raw-score urgency.
Denial of service in IBM i 7.3 through 7.6 allows remote unauthenticated attackers to crash or hang affected systems by triggering an infinite loop condition (CWE-835) over the network. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms the attack requires no authentication and minimal complexity, making automated exploitation straightforward. No public exploit code or active exploitation via CISA KEV has been identified at time of analysis.
Denial of service in IBM i 7.3 through 7.6 allows remote unauthenticated attackers to exhaust system resources through unbounded resource allocation, rendering the platform unavailable to legitimate users. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms exploitation requires no authentication and no user interaction, with low attack complexity over the network. No public exploit code and no CISA KEV entry have been identified at the time of analysis; a vendor patch is available.
Remote denial of service in IBM i 7.3 through 7.6 is achievable by an unauthenticated network attacker via a CWE-835 infinite loop condition. Per the CVSS vector (AV:N/AC:L/PR:N/UI:N), exploitation requires no authentication and no user interaction against affected systems. No public exploit code or active exploitation confirmed at time of analysis; IBM has released a patch.

The vulnerability is rooted in CWE-787 (out-of-bounds write) and carries a CVSS 3.1 base score of 7.5 (High) with a fully unauthenticated network attack vector. No public exploit code or CISA KEV listing has been identified at time of analysis; IBM has released a patch through its support portal.
Unauthenticated remote exploitation of a buffer overflow in IBM i 7.3 through 7.6 allows attackers to cause denial of service and modify authentication metadata without any credentials or user interaction. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms trivially reachable exploitation over the network against default-accessible services. IBM has released a patch; no public exploit code or CISA KEV listing has been identified at time of analysis.
Authentication bypass in IBM i (the operating system for IBM Power/AS-400 midrange systems) versions 7.3, 7.4, 7.5, and 7.6 allows remote attackers to circumvent security restrictions because the system improperly validates a client-asserted identity (CWE-287). Because a caller's claimed identity is trusted without adequate verification, an attacker can impersonate another principal and gain unauthorized access to protected resources with full confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis, and the EPSS probability is low (0.34%, 27th percentile), but the CVSS 9.8 rating and network-reachable, unauthenticated vector make this a high-priority patch.
Local privilege escalation in IBM i versions 7.3 through 7.6 allows an authenticated local user with low-level system privileges to gain elevated authority due to improper privilege management (CWE-269). The CVSS vector (AV:L/AC:L/PR:L/UI:N) confirms exploitation requires no special conditions beyond existing local access, with full confidentiality, integrity, and availability impact upon success. No public exploit code has been identified at time of analysis, and IBM has released a patch via its support portal.
Memory-corruption in IBM Db2's IXF file IMPORT parser lets an attacker supply a crafted IXF data file that overflows a stack buffer (CWE-121), affecting Db2 11.5.0 through 11.5.9 and 12.1.0 through 12.1.5 on all listed platforms. Successful exploitation can crash the database engine or lead to code execution in the Db2 server process, yielding total loss of confidentiality, integrity, and availability. IBM has released a fix; there is no public exploit identified at time of analysis and CISA SSVC currently rates exploitation as 'none'.
Remote unauthenticated denial of service and sensitive information disclosure in IBM i 7.3 through 7.6 stems from an integer underflow (CWE-125 out-of-bounds read) reachable over the network without authentication. An attacker sending a crafted request can crash an affected service and read portions of process memory, yielding both high availability impact and limited confidentiality exposure. No public exploit code has been identified at time of analysis and this CVE is not listed in the CISA KEV catalog, though the low-complexity, unauthenticated attack vector makes it a meaningful risk for internet-exposed IBM i systems.
Remote unauthenticated OS command injection in IBM Informix Dynamic Server 12.10, 14.10, and 15.0 allows network-accessible attackers to execute arbitrary system commands under the Informix service account without any credentials or user interaction. Rooted in CWE-78, the flaw arises from insufficient validation of user-supplied input before it is passed to OS-level execution routines, spanning three major version branches of the product. No CISA KEV listing or public proof-of-concept has been identified at time of analysis; a vendor patch is available via the IBM advisory.
Local privilege escalation in IBM Informix Dynamic Server 14.10 and 15.0 allows any low-privileged local OS user to gain root access by exploiting improper access controls in the setuid-root `oninit` utility. The CVSS vector (AV:L/AC:L/PR:L/UI:N) confirms a low-complexity local attack requiring no user interaction, resulting in full system compromise. No public exploit has been identified at time of analysis, and this vulnerability is not currently listed in the CISA KEV catalog.
Privilege escalation in IBM Db2 (data server versions 11.5.0-11.5.9 and 12.1.0-12.1.5) allows an attacker to submit a specially crafted query that bypasses authorization controls and gains elevated database privileges, classified as CWE-285 improper authorization. IBM reported the issue and has published a fix; there is no public exploit identified at time of analysis and it is not on CISA KEV. EPSS is low at 0.32% (25th percentile) despite the 9.8 CVSS, indicating no observed mass-exploitation activity yet.
IBM Db2 versions 11.5.0 through 11.5.9 and 12.1.0 through 12.1.5 expose an improper authorization flaw in certain database commands, enabling a low-privileged authenticated user to bypass server-side authority checks and directly modify database catalog data. The root cause is CWE-602 (client-side enforcement of server-side security), where authorization validation is not properly enforced at the server layer. No public exploit has been identified and SSVC rates exploitation as none currently, though the high integrity impact against catalog metadata - which governs schema definitions and access control structures - makes this a meaningful patching priority for all affected Db2 deployments.
Arbitrary code execution is achievable on Windows endpoints running IBM i Access Client Solutions (ACS) 1.1.2.0 through 1.1.9.13 when the software is installed in all-users mode, because the installer leaves one or more configuration files world-writable. Any local user with standard (non-administrator) privileges can modify these files to inject code that executes under the security context of other users who subsequently launch the application. No public exploit code or CISA KEV listing has been identified at time of analysis; however, the CVSS 7.8 High rating reflects the full confidentiality, integrity, and availability impact achievable once a local foothold exists.
Code-integrity failure in IBM i Access Client Solutions (ACS) versions 1.1.2.0 through 1.1.9.13 lets a positioned attacker deliver unverified, compromised product code to a user's workstation when ACS is configured to auto-update from an IBM i host. Because ACS does not validate the integrity/authenticity of downloaded update code (CWE-494), an attacker who can serve or tamper with that update stream can achieve arbitrary code execution on the client machine. Carries a vendor CVSS of 9.6 (adjacent, scope-changed, full CIA impact), but there is no public exploit identified at time of analysis and EPSS is very low at 0.11%.
Zip slip path traversal in IBM i Access Client Solutions 1.1.2.0 through 1.1.9.13 allows a network-positioned attacker to write arbitrary files outside the intended extraction directory when a victim imports a maliciously crafted configuration archive. The CVSS vector (AV:N/AC:L/PR:N/UI:R) confirms the attack is network-deliverable with low complexity but requires the target user to actively import the crafted configuration - a social engineering dependency that is the primary limiting factor. No public exploit or CISA KEV listing has been identified at time of analysis; vendor patch is confirmed available.
OS command injection in IBM i Access Client Solutions versions 1.1.2.0 through 1.1.9.13 enables a local attacker to execute arbitrary code on the underlying operating system. Exploitation requires user interaction (UI:R) but no prior privileges (PR:N), suggesting the attack vector involves a maliciously crafted file or input that a victim opens or processes with the client application. IBM has released a patch via advisory node/7282954, and no public exploit or CISA KEV listing has been identified at time of analysis.
Privilege escalation in IBM Security Verify Access and IBM Verify Identity Access allows an authenticated low-privilege user to assume the identity and privileges of another user by submitting a specially crafted network request. The vulnerability spans both on-premises and container deployments across multiple product generations (10.x and 11.x lines), broadening the exposed surface considerably. No public exploit code or CISA KEV listing has been identified at time of analysis, but the CVSS score of 8.1 and low attack complexity make this a high-priority patching target for organizations running IBM identity infrastructure.
Privilege escalation via command injection in IBM Security Verify Access and IBM Verify Identity Access allows an authenticated administrator to execute system commands beyond their authorized scope. Affected products span IBM Security Verify Access 10.0 through 10.0.9.2 and IBM Verify Identity Access 11.0 through 11.0.3 (including the container variant), with network-accessible administrative interfaces as the attack surface. Full confidentiality, integrity, and availability compromise of the underlying system is possible; no public exploit identified at time of analysis and this vulnerability is not listed in the CISA KEV catalog.
Authentication bypass in IBM Security Verify Access and IBM Verify Identity Access exposes protected resources to unauthenticated remote attackers via inconsistent HTTP request parsing at the reverse proxy layer. Affected deployments span IBM Security Verify Access 10.0-10.0.9.2 and IBM Verify Identity Access 11.0-11.0.3 (software and container variants). No public exploit or CISA KEV listing has been identified at time of analysis, but the identity gateway role of this product means a successful bypass could silently undermine authentication enforcement across all downstream resources it protects.
OS command injection in IBM Security Verify Access and IBM Verify Identity Access management interfaces enables already-privileged administrators to execute arbitrary operating system commands beyond their intended scope by submitting crafted HTTP requests to the vulnerable endpoint. Affected deployments span IBM Security Verify Access 10.0-10.0.9.2, IBM Verify Identity Access 11.0-11.0.3, and the containerized variant of the latter - covering both legacy on-premises and modern container-based identity infrastructure. No public exploit code or CISA KEV listing has been identified at time of analysis; however, the full confidentiality, integrity, and availability impact against identity management infrastructure elevates organizational risk well beyond what the PR:H prerequisite might suggest at face value.
Format string injection in IBM Security Verify Access (10.0-10.0.9.2) and IBM Verify Identity Access (11.0-11.0.3, including container deployments) enables authenticated administrative attackers to send crafted HTTP requests to the management interface, triggering uncontrolled format string processing. Successful exploitation produces high confidentiality impact through stack memory disclosure and high availability impact through service crashes, with CVSS scope change indicating potential downstream effect on identity services beyond the management component. No public exploit is identified at time of analysis; this is a vendor-confirmed finding reported directly by IBM PSIRT.
Arbitrary code execution on IBM Power Systems host is achievable by any attacker who already holds service account or root access to the BMC or FSP management controller. The vulnerability resides in the interface layer between the BMC/FSP and the host, where missing authorization checks (CWE-862) allow an authenticated BMC-level principal to cross the trust boundary and execute code with full host-system privileges. All hosted logical partitions are consequently exposed, making this a critical lateral-movement and privilege-escalation path within IBM Power infrastructure. No public exploit code or CISA KEV listing has been identified at time of analysis.
Stack-based buffer overflow in IBM Power Firmware's host firmware configuration parser allows an attacker with service-level access to the BMC/FSP to supply specially crafted configuration data, triggering CWE-121 during the firmware boot stage and compromising the entire software stack loaded thereafter. Affected firmware spans multiple major release trains - FW1120, FW1110, FW1060, FW950, and OP940 - covering Power9 and Power HMC managed systems. No public exploit has been identified at the time of analysis, and a vendor patch is available from IBM.
Arbitrary code execution in IBM Power Firmware across multiple firmware branches (FW1120.00, FW1110.x, FW1060.x, FW950.x, OP940.x) stems from a CWE-787 out-of-bounds write in the service processor mailbox interface. An authenticated attacker with service-level access to the BMC/FSP can exploit this buffer overflow to cross the trust boundary from the management processor into the host firmware runtime, gaining full control over the managed Power system. No public exploit has been identified at time of analysis; IBM has released a patch per advisory 7283236.
Arbitrary code execution on IBM Power host systems is possible when an attacker with service processor access supplies a maliciously crafted firmware update image that bypasses boot-time image validation. Affected firmware versions span three release trains: FW1120.00, FW1110.00-FW1110.30, and FW1060.00-FW1060.80. Exploitation yields full confidentiality, integrity, and availability impact on the host, with scope change indicating the compromise extends beyond the service processor itself. No public exploit or CISA KEV listing is identified at this time.
Unauthenticated remote attackers can overwrite administrator email addresses and abuse IBM Langflow OSS as an outbound mail relay by exploiting a missing authentication control on the registration endpoint, affecting versions 1.0.0 through 1.10.0. The CVSS vector AV:N/AC:L/PR:N/UI:N confirms trivially reachable exploitation with no credentials or user interaction required. No public exploit or CISA KEV listing has been identified at time of analysis, though the low attack complexity makes this viable for opportunistic exploitation once the endpoint is discovered.
IBM AIX 7.2 and 7.3, along with IBM PowerVM VIOS 4.1, expose a time-of-check time-of-use (TOCTOU) race condition that local, unprivileged attackers can exploit to corrupt data integrity or crash the system. The flaw requires only local shell access with no privileges, making it exploitable by any local user account on affected POWER-architecture systems. No public exploit code or CISA KEV listing exists at time of analysis, though a vendor patch is available.
Uncontrolled resource consumption in IBM AIX 7.2, 7.3 and PowerVM VIOS 4.1 exposes these systems to remote denial-of-service attacks requiring no authentication or user interaction. The CVSS vector AV:N/AC:L/PR:N/UI:N confirms any network-reachable attacker can trigger availability loss without special privileges. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis, and a vendor patch is available.
IBM AIX 7.2 and 7.3, and PowerVM VIOS 4.1 expose an unauthenticated remote denial-of-service condition rooted in a NULL pointer dereference.

No public exploit code or active exploitation has been identified at time of analysis; IBM has released a patch addressed in advisory node/7283858.
Unauthenticated remote access to NFS-exported filesystems is possible in IBM AIX 7.2 and 7.3 and IBM PowerVM VIOS 4.1 due to improper authentication (CWE-287). The CVSS vector AV:N/AC:L/PR:N/UI:N confirms that unauthenticated remote attackers on the network can exploit this with low complexity and no user interaction, gaining high-confidence read access and limited write access to exported filesystem data. No public exploit has been identified at time of analysis, and IBM has released a patch via advisory 7283858.
Remote denial of service in IBM AIX 7.2/7.3 and PowerVM VIOS 4.1 is exploitable by unauthenticated attackers who send malformed client registration packets to the NIM (Network Installation Manager) server, triggering a classic buffer overflow that crashes the nimserver daemon. The CVSS 7.5 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) confirms low-complexity, network-accessible exploitation requiring no privileges, though impact is strictly limited to availability - no confidentiality or integrity exposure is present. IBM has released a patch via support advisory 7283858; no public exploit code has been identified and this vulnerability does not appear on the CISA KEV catalog at time of analysis.
Remote privilege escalation to root in IBM AIX 7.2 and 7.3 and IBM PowerVM VIOS 4.1 stems from an improper authentication weakness (CWE-287) that lets an unauthenticated network attacker bypass identity checks and obtain root-level control. The CVSS 9.8 rating reflects a network-reachable, low-complexity flaw requiring no privileges or user interaction, with full confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the severity and unauthenticated network vector make it a high-priority patching target for IBM Power estates.
Improper TLS certificate validation in the NIM (Network Installation Management) subsystem of IBM AIX 7.2, 7.3, and IBM PowerVM VIOS 4.1 enables remote attackers to gain unauthorized access to AIX systems by exploiting the failure to verify certificate authenticity during NIM communications. The CVSS 8.1 High score reflects high confidentiality and integrity impact across a network-exploitable path with low complexity and no user interaction required. No public exploit identified at time of analysis, but the authentication bypass classification of this flaw makes it a meaningful privilege escalation and lateral movement risk in IBM Power environments.
OS command injection in IBM AIX 7.2/7.3 and PowerVM VIOS 4.1 lets a remote authenticated attacker run arbitrary commands through the Network Installation Manager (NIM) component. Because NIM typically operates with high (often root-level) privilege and the CVSS scope is Changed, successful exploitation can compromise the underlying operating system with full confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis and it is not on CISA KEV, but the 9.9 base score and low attack complexity make it a high-priority patch for IBM Power estates.
Sensitive-key exposure in IBM AIX 7.2/7.3 and PowerVM VIOS 4.1 Network Installation Management (NIM) leaks intermediate certificate authority (CA) private keys inside a publicly downloadable update file, letting remote attackers forge trusted certificates and bypass security restrictions. Rated CVSS 9.1, the flaw impacts confidentiality and integrity (C:H/I:H) but not availability, and IBM has released a fix. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the ease of obtaining a live CA key makes this a high-priority credential-hygiene issue.
Unauthenticated remote file overwrite in IBM AIX 7.2/7.3 and PowerVM VIOS 4.1 is possible via the nimesis registration service, which fails to sanitize path traversal sequences in client-supplied input. An attacker with network access to the nimesis service can write arbitrary content to locations outside the intended directory, potentially overwriting sensitive system files such as cron jobs, init scripts, or authentication databases. No public exploit or active exploitation has been identified at time of analysis, though the CVSS vector (AV:N/AC:L/PR:N/UI:N) indicates this is straightforwardly exploitable without authentication.
Sensitive file disclosure in IBM Db2 Mirror for i versions 7.4, 7.5, and 7.6 is possible through a path traversal flaw (CWE-22) that allows attackers to escape a restricted directory boundary and read files outside the intended accessible path, resulting in high confidentiality impact. The CVE description attributes the exposure to a remote authenticated attacker, though this conflicts with the NVD-assigned CVSS vector - a discrepancy security teams must resolve before finalizing triage. A vendor patch is available via IBM Support advisory node/7283359; no public exploit code or CISA KEV listing has been identified at time of analysis.
Arbitrary file deletion in IBM Db2 Mirror for i versions 7.4, 7.5, and 7.6 is achievable by remote authenticated attackers holding only low-privileged credentials, exploiting a path traversal flaw that bypasses directory boundary enforcement to reference and delete files anywhere on the target filesystem. The CVSS 3.1 score of 8.1 reflects high integrity and availability impact with low attack complexity, though the EPSS score of 0.44% at the 37th percentile signals limited observed exploitation probability at time of analysis. No public exploit code has been identified and this vulnerability does not appear in the CISA KEV catalog.
Remote CL command execution in IBM Db2 Mirror for i 7.4, 7.5, and 7.6 lets a remote attacker run arbitrary Control Language commands on the IBM i host because special elements in a command are not properly neutralized (CWE-78). The CVSS 3.1 base score is 9.8 with a fully network-facing, no-privilege, no-interaction vector, meaning an unauthenticated remote attacker can achieve high-impact code execution. There is no public exploit identified at time of analysis and EPSS is modest at 0.47% (39th percentile), but the combination of unauthenticated network reach and full CIA impact makes this a high-priority patch.
Remote code execution in IBM Db2 Mirror for i (versions 7.4, 7.5, and 7.6) allows a remote unauthenticated attacker to run arbitrary code by exploiting external control of a file name or path (CWE-73). The flaw carries a CVSS 9.8 rating with a network attack vector and no privileges or user interaction required, and IBM has published a fix. No public exploit code or active exploitation has been identified at time of analysis.
Authentication bypass in IBM Db2 Mirror for i (versions 7.4, 7.5, and 7.6) lets a remote, unauthenticated attacker read or modify sensitive information by exploiting improper validation of request URI path segments. Because the flaw is reachable over the network without credentials or user interaction, an attacker can defeat access controls on the replication/administration interface and reach protected functionality or data. No public exploit has been identified at time of analysis, but the maximal CVSS 9.8 rating and the low attack complexity make this a high-priority patching target.
Arbitrary file write via path traversal in IBM Db2 Mirror for i 7.4, 7.5, and 7.6 enables remote unauthenticated attackers to place files at any location on the underlying IBM i system. The CVSS vector (AV:N/AC:L/PR:N/UI:N/S:C/I:H) confirms network-reachable exploitation without authentication, with a scope change indicating impact beyond the Db2 Mirror application itself - reaching OS-level paths. No public exploit or KEV listing has been identified at time of analysis, and an EPSS of 0.59% (46th percentile) suggests low observed exploitation activity despite the high CVSS base score.
Uncontrolled recursion in IBM Db2 Mirror for i versions 7.4, 7.5, and 7.6 enables remote unauthenticated attackers to crash the service, resulting in a complete loss of availability. The CVSS vector (AV:N/AC:L/PR:N/UI:N) confirms the flaw is exploitable over the network without credentials or user interaction, making it trivially reachable in any internet- or network-exposed deployment. No public exploit code or active exploitation (CISA KEV) has been identified at the time of analysis, but the low attack complexity elevates practical risk.
Arbitrary file write via path traversal in IBM Db2 Mirror for i versions 7.4, 7.5, and 7.6 exposes systems to unauthenticated remote exploitation. The flaw stems from improper pathname restriction (CWE-22), enabling an attacker to escape the intended directory sandbox and write files to arbitrary filesystem locations. No active exploitation has been confirmed in CISA KEV, and no public proof-of-concept exploit is known at the time of analysis, though the CVSS 8.2 High rating and network-accessible attack vector make this a credible priority for organizations running IBM i environments.
Path traversal in IBM Db2 Mirror for i versions 7.4, 7.5, and 7.6 enables remote authenticated attackers to read sensitive files outside intended directory boundaries due to improper input validation (CWE-22). The vulnerability results in high confidentiality impact with no integrity or availability consequence. No public exploit code or active exploitation has been identified at time of analysis; a vendor-released patch is available via IBM support advisory node 7283359.
Security restriction bypass in IBM Db2 Mirror for i 7.4, 7.5, and 7.6 permits remote authenticated attackers to exceed their authorized privilege level via manipulated user-supplied input processed without adequate authorization checks. With a CVSS score of 8.8 and full confidentiality, integrity, and availability impact, exploitation could allow an attacker with only low-privilege credentials to read, modify, or disrupt mirrored database content. No public exploit code and no CISA KEV listing have been identified at time of analysis, though a vendor patch is available.
IBM Db2 Mirror for i versions 7.4, 7.5, and 7.6 exposes a network-accessible pathway through which an unauthenticated remote attacker can externally influence system configuration settings (CWE-15), enabling disclosure of sensitive information and - per the CVSS vector - potential integrity and availability compromise as well. The changed scope (S:C) in the CVSS vector indicates the vulnerability can propagate impact beyond the directly affected component, consistent with how mirror configuration alterations can affect the paired IBM i high-availability node. A vendor-released patch is available via IBM Support; no public exploit code exists and the vulnerability is not listed in the CISA KEV catalog at time of analysis.
Account takeover in IBM Langflow OSS versions 1.0.0 through 1.9.6 is possible because the platform fails to limit repeated failed authentication attempts (CWE-307), letting remote attackers brute-force or credential-stuff their way into user accounts. IBM (the reporting vendor) rates it CVSS 9.1 with high confidentiality and integrity impact, reflecting full compromise of a targeted account. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the missing lockout control is trivial to abuse against weak or reused credentials.
Stack-based buffer overflow in the Native IBM i JSSE (Java Secure Socket Extension) provider enables local authenticated attackers with low privileges to execute arbitrary code or crash the JVM process on IBM i versions 7.3 through 7.6. The flaw is triggered during TLS session establishment via improper bounds checking against a fixed-length stack buffer. No public exploit or active exploitation has been identified at time of analysis - EPSS stands at 0.22% (12th percentile) and SSVC exploitation status is 'none' - but a vendor patch is available and should be applied given the high-impact code execution potential.
Privilege escalation in IBM i versions 7.3 through 7.6 allows a local authenticated attacker to abuse improper authorization controls in the Navigator for i debugger component to access or manipulate sensitive system data, or create new profiles with elevated privileges. The vulnerability is classified under CWE-285 (Improper Authorization), indicating the debugger fails to enforce sufficient privilege checks before granting access to sensitive operations. No public exploit or CISA KEV listing exists at time of analysis, though SSVC assesses the technical impact as total should exploitation occur.
Privilege escalation in IBM i (7.3, 7.4, 7.5, 7.6) lets a remote, authenticated attacker gain elevated privileges by abusing improper validation of pointers read from Java-controlled addresses, giving full compromise of the affected component and a scope-changing impact beyond it. IBM assigned a critical CVSS 9.9 (S:C) despite requiring low privileges. No public exploit identified at time of analysis, and CISA SSVC records exploitation status as none, so this is a patch-worthy critical without evidence of active abuse yet.
Security-restriction bypass in IBM i (the operating system for IBM Power servers, formerly OS/400) versions 7.3 through 7.6 lets a remote attacker abuse improper validation of user-controlled addresses to elevate privileges and cross a security boundary.

Memory-corruption in IBM Db2's IXF file IMPORT parser lets an attacker supply a crafted IXF data file that overflows a stack buffer (CWE-121), affecting Db2 11.5.0 through 11.5.9 and 12.1.0 through 12.1.5 on all listed platforms. Successful exploitation can crash the database engine or lead to code execution in the Db2 server process, yielding total loss of confidentiality, integrity, and availability. IBM has released a fix; there is no public exploit identified at time of analysis and CISA SSVC currently rates exploitation as 'none'.
Remote unauthenticated denial of service and sensitive information disclosure in IBM i 7.3 through 7.6 stems from an integer underflow (CWE-125 out-of-bounds read) reachable over the network without authentication. An attacker sending a crafted request can crash an affected service and read portions of process memory, yielding both high availability impact and limited confidentiality exposure. No public exploit code has been identified at time of analysis and this CVE is not listed in the CISA KEV catalog, though the low-complexity, unauthenticated attack vector makes it a meaningful risk for internet-exposed IBM i systems.
Remote unauthenticated OS command injection in IBM Informix Dynamic Server 12.10, 14.10, and 15.0 allows network-accessible attackers to execute arbitrary system commands under the Informix service account without any credentials or user interaction. Rooted in CWE-78, the flaw arises from insufficient validation of user-supplied input before it is passed to OS-level execution routines, spanning three major version branches of the product. No CISA KEV listing or public proof-of-concept has been identified at time of analysis; a vendor patch is available via the IBM advisory.
Local privilege escalation in IBM Informix Dynamic Server 14.10 and 15.0 allows any low-privileged local OS user to gain root access by exploiting improper access controls in the setuid-root `oninit` utility. The CVSS vector (AV:L/AC:L/PR:L/UI:N) confirms a low-complexity local attack requiring no user interaction, resulting in full system compromise. No public exploit has been identified at time of analysis, and this vulnerability is not currently listed in the CISA KEV catalog.
Privilege escalation in IBM Db2 (data server versions 11.5.0-11.5.9 and 12.1.0-12.1.5) allows an attacker to submit a specially crafted query that bypasses authorization controls and gains elevated database privileges, classified as CWE-285 improper authorization. IBM reported the issue and has published a fix; there is no public exploit identified at time of analysis and it is not on CISA KEV. EPSS is low at 0.32% (25th percentile) despite the 9.8 CVSS, indicating no observed mass-exploitation activity yet.
IBM Db2 versions 11.5.0 through 11.5.9 and 12.1.0 through 12.1.5 expose an improper authorization flaw in certain database commands, enabling a low-privileged authenticated user to bypass server-side authority checks and directly modify database catalog data. The root cause is CWE-602 (client-side enforcement of server-side security), where authorization validation is not properly enforced at the server layer. No public exploit has been identified and SSVC rates exploitation as none currently, though the high integrity impact against catalog metadata - which governs schema definitions and access control structures - makes this a meaningful patching priority for all affected Db2 deployments.
Arbitrary code execution is achievable on Windows endpoints running IBM i Access Client Solutions (ACS) 1.1.2.0 through 1.1.9.13 when the software is installed in all-users mode, because the installer leaves one or more configuration files world-writable. Any local user with standard (non-administrator) privileges can modify these files to inject code that executes under the security context of other users who subsequently launch the application. No public exploit code or CISA KEV listing has been identified at time of analysis; however, the CVSS 7.8 High rating reflects the full confidentiality, integrity, and availability impact achievable once a local foothold exists.
Code-integrity failure in IBM i Access Client Solutions (ACS) versions 1.1.2.0 through 1.1.9.13 lets a positioned attacker deliver unverified, compromised product code to a user's workstation when ACS is configured to auto-update from an IBM i host. Because ACS does not validate the integrity/authenticity of downloaded update code (CWE-494), an attacker who can serve or tamper with that update stream can achieve arbitrary code execution on the client machine. Carries a vendor CVSS of 9.6 (adjacent, scope-changed, full CIA impact), but there is no public exploit identified at time of analysis and EPSS is very low at 0.11%.
Zip slip path traversal in IBM i Access Client Solutions 1.1.2.0 through 1.1.9.13 allows a network-positioned attacker to write arbitrary files outside the intended extraction directory when a victim imports a maliciously crafted configuration archive. The CVSS vector (AV:N/AC:L/PR:N/UI:R) confirms the attack is network-deliverable with low complexity but requires the target user to actively import the crafted configuration - a social engineering dependency that is the primary limiting factor. No public exploit or CISA KEV listing has been identified at time of analysis; vendor patch is confirmed available.
OS command injection in IBM i Access Client Solutions versions 1.1.2.0 through 1.1.9.13 enables a local attacker to execute arbitrary code on the underlying operating system. Exploitation requires user interaction (UI:R) but no prior privileges (PR:N), suggesting the attack vector involves a maliciously crafted file or input that a victim opens or processes with the client application. IBM has released a patch via advisory node/7282954, and no public exploit or CISA KEV listing has been identified at time of analysis.
Privilege escalation in IBM Security Verify Access and IBM Verify Identity Access allows an authenticated low-privilege user to assume the identity and privileges of another user by submitting a specially crafted network request. The vulnerability spans both on-premises and container deployments across multiple product generations (10.x and 11.x lines), broadening the exposed surface considerably. No public exploit code or CISA KEV listing has been identified at time of analysis, but the CVSS score of 8.1 and low attack complexity make this a high-priority patching target for organizations running IBM identity infrastructure.
Privilege escalation via command injection in IBM Security Verify Access and IBM Verify Identity Access allows an authenticated administrator to execute system commands beyond their authorized scope. Affected products span IBM Security Verify Access 10.0 through 10.0.9.2 and IBM Verify Identity Access 11.0 through 11.0.3 (including the container variant), with network-accessible administrative interfaces as the attack surface. Full confidentiality, integrity, and availability compromise of the underlying system is possible; no public exploit identified at time of analysis and this vulnerability is not listed in the CISA KEV catalog.
Authentication bypass in IBM Security Verify Access and IBM Verify Identity Access exposes protected resources to unauthenticated remote attackers via inconsistent HTTP request parsing at the reverse proxy layer. Affected deployments span IBM Security Verify Access 10.0-10.0.9.2 and IBM Verify Identity Access 11.0-11.0.3 (software and container variants). No public exploit or CISA KEV listing has been identified at time of analysis, but the identity gateway role of this product means a successful bypass could silently undermine authentication enforcement across all downstream resources it protects.
OS command injection in IBM Security Verify Access and IBM Verify Identity Access management interfaces enables already-privileged administrators to execute arbitrary operating system commands beyond their intended scope by submitting crafted HTTP requests to the vulnerable endpoint. Affected deployments span IBM Security Verify Access 10.0-10.0.9.2, IBM Verify Identity Access 11.0-11.0.3, and the containerized variant of the latter - covering both legacy on-premises and modern container-based identity infrastructure. No public exploit code or CISA KEV listing has been identified at time of analysis; however, the full confidentiality, integrity, and availability impact against identity management infrastructure elevates organizational risk well beyond what the PR:H prerequisite might suggest at face value.
Format string injection in IBM Security Verify Access (10.0-10.0.9.2) and IBM Verify Identity Access (11.0-11.0.3, including container deployments) enables authenticated administrative attackers to send crafted HTTP requests to the management interface, triggering uncontrolled format string processing. Successful exploitation produces high confidentiality impact through stack memory disclosure and high availability impact through service crashes, with CVSS scope change indicating potential downstream effect on identity services beyond the management component. No public exploit is identified at time of analysis; this is a vendor-confirmed finding reported directly by IBM PSIRT.
