MITRE ATT&CK
2 techniques across 2 tactics: Execution, Privilege Escalation The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires the attacker to already hold administrative privileges AND have access to the local management interface of IBM Security Verify Access (10.0 through 10.0.9.2) or IBM Verify Identity Access (11.0 through 11.0.3), including their container variants. The code execution is triggered by supplying input that exceeds a fixed-size stack buffer (CWE-787 unbounded write). Limiting factors: this is not reachable by unauthenticated or low-privileged users - it presupposes administrative control of the appliance's management plane, which should itself be network-segmented and access-restricted; there is no user-interaction requirement (UI:N) and attack complexity is low (AC:L), so once an admin can reach the management interface the overflow is reliably triggerable. |
| Impact | This is a high-CVSS (7.2) but comparatively low-real-world-urgency issue. The CVSS vector (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) requires PR:H - confirmed authenticated with administrative privileges - and the description further narrows this to attackers who already have access to the local management interface. All signals align on low current risk: SSVC reports Exploitation=none and Automatable=no with only partial technical impact, there is no CISA KEV listing, and no public exploit was identified. Note a tension to verify with the vendor: the CVSS vector asserts AV:N (network) while the description states the attacker needs access to the 'local management interface,' which implies restricted/management-plane reachability rather than open internet exposure - the network vector likely reflects the web-based admin console rather than unauthenticated internet access. The practical consequence is that an already-privileged administrator can escalate from configuration control to arbitrary code execution on the appliance (a trust-boundary / defense-in-depth break), which is meaningful for hardening but not a mass-exploitation priority. Patch availability from IBM makes this straightforward to remediate during normal maintenance. |
| Exploit ScenarioDerived | An attacker who has already obtained administrative credentials for the IBM Security Verify Access / Verify Identity Access management interface submits an oversized value to a vulnerable input field, overflowing a fixed-size stack buffer and executing arbitrary code on the underlying appliance. No public exploit code has been identified, and exploitation is gated behind existing administrative access, so this is realistically an insider or post-compromise privilege/trust-boundary escalation rather than an initial access vector. |

Arbitrary code execution is possible in IBM Security Verify Access 10.0 through 10.0.9.2 and IBM Verify Identity Access 11.0 through 11.0.3 (including their container editions) when an attacker who already holds administrative privileges on the appliance and can reach the local management interface supplies input that overflows a fixed-size stack buffer. The assessed CVSS 3.1 base score is 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) with CWE-787 as the root cause, so the flaw is high-severity on impact but gated by a strong prerequisite: administrative control of the management plane rather than unauthenticated reach. Patch available per vendor advisory (IBM support page node/7291628); there is no CISA KEV entry and no public exploit code identified at time of analysis, and CISA SSVC decision points record Exploitation: none, Automatable: no, Technical Impact: partial.
Earlier versions of this analysis (1)
Arbitrary code execution is possible on IBM Security Verify Access 10.0 through 10.0.9.2 and IBM Verify Identity Access 11.0 through 11.0.3, including their containerized editions, but only for an attacker who already holds administrative privileges and has access to the local management interface (LMI). The flaw is an unbounded write into a fixed-size stack buffer (CWE-787) reachable through LMI input, which can corrupt memory and, under the conditions described, lead to code execution. With a CVSS base of 5.5 (AV:N/AC:H/PR:H/UI:N/S:U/C:L/I:L/A:H), the requirement for pre-existing admin authentication drastically narrows the attacker population to malicious insiders or actors who have already compromised administrative credentials; no public exploit code has been identified at time of analysis and the issue is not in CISA KEV.
RemediationAI
Apply the vendor fix documented in the IBM advisory (https://www.ibm.com/support/pages/node/7291628); patch availability is confirmed by IBM but no exact fixed build string is provided in the source data, so consult the advisory for the specific 10.0.x and 11.0.x maintenance levels that remediate the overflow and upgrade the appliance and any container images to those levels. Because exploitation requires an authenticated administrator with access to the local management interface, the most effective compensating controls are tightening that management plane: restrict the management interface to a dedicated, network-segmented administrative VLAN or bastion host and block it from general user and internet-facing networks (trade-off: administrators must route through the jump host, adding operational friction); disable or firewall any management endpoints that are not in active use, including leaving remote management off where an on-console workflow is viable; and enforce least privilege and strong authentication on administrative accounts with prompt credential rotation for any account that had management access, since a compromised admin is the sole prerequisite for this flaw. These mitigations reduce exposure but do not eliminate the underlying unbounded stack write, so patching remains the only complete fix; detection should focus on unexpected crashes or restarts of management services, which are the most likely visible symptom of an attempted overflow.

Technical ContextAI · show details
The defect is an out-of-bounds write (CWE-787) in which attacker-controlled input is copied into a fixed-size stack buffer without a length check, corrupting adjacent stack memory and allowing control-flow hijack and code execution in the context of the management service. The affected code path sits behind the local management interface of the identity/access-management appliance, which is why the CVSS vector carries PR:H: exploitation is only reachable by an authenticated administrator with local management access, even though AV:N/AC:L/UI:N indicate a remote transport and a reliable, low-complexity trigger once that interface is reachable. The CPE data confirms four affected artifacts in the same code family - ibm:security_verify_access, ibm:verify_identity_access, ibm:security_verify_access_container, and ibm:verify_identity_access_container - so the appliance, the standalone product, and their containerized distributions all share the vulnerable buffer-handling code. Because the corruption is a classic stack overflow rather than a logic error, reliability of the exploit is limited mainly by memory-layout factors, which is consistent with the SSVC 'Automatable: no' assessment.

Lifecycle Timeline
2DescriptionNVD
IBM Security Verify Access 10.0 through 10.0.9.2 and IBM Verify Identity Access 11.0 through 11.0.3 could allow an attacker with administrative privileges and access to the local management interface to execute arbitrary code due to an unbounded write to a fixed-size stack buffer.
Executive ViewAI
IBM Security Verify Access (10.0-10.0.9.2) and IBM Verify Identity Access (11.0-11.0.3), including container editions, contain a high-severity buffer overflow that can lead to arbitrary code execution by an authenticated administrative user with local management interface access. Although exploitation requires prior administrative privileges, a successful attack could compromise the integrity and availability of critical identity and access management services, potentially enabling broader unauthorized access to protected systems. Security leadership should prioritize patching to mitigate risks from insider threats or compromised administrative accounts.

The engine reads each signal below and applies a fixed list of rules from top to bottom. The first rule that matches sets the recommended action – like a statement, every line is shown.
What every action level means
SSVC AssessmentENISA
Priority Score
Attack Technique
A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
