Remote code execution in Rockwell Automation Arena's DOE file parser allows a network-reachable attacker to write beyond the boundary of an allocated object and execute arbitrary code within the context of the running Arena process. Affected users must be socially engineered into opening a maliciously crafted Design of Experiments (DOE) file or visiting a page that triggers the parse. The CVSS 4.0 score of 7.5 reflects high attack complexity and mandatory active user interaction, reducing real-world exploitability despite the high-severity memory corruption impact. No public exploit code or CISA KEV listing has been identified at time of analysis.
Privilege escalation in Rockwell Automation's Redundancy Module Configuration Tool (RMConfigTool.exe) enables a local standard user to execute arbitrary code with Administrator or SYSTEM privileges via DLL search order hijacking. The tool searches system PATH directories for required DLLs, and one or more of those directories have incorrect default permissions allowing write access by non-privileged accounts; if a malicious DLL is planted there before an administrator runs the tool, it loads into the elevated process. No public exploit has been identified at time of analysis, and the vulnerability is not listed in CISA KEV, though the underlying technique is well-understood and commonly leveraged in post-exploitation privilege escalation chains.
DLL hijacking in Rockwell Automation's Redundancy Module Configuration Tool (RM3ConfigTool.exe) allows a local low-privileged attacker to escalate to Administrator or SYSTEM privileges by planting a malicious DLL in a writable system PATH directory before an administrator launches the utility. The root cause is CWE-276 (Incorrect Default Permissions): the installer grants standard users write access to one or more directories that RM3ConfigTool.exe searches at runtime for a required DLL, enabling the classic DLL planting technique. No public exploit code has been identified at the time of analysis, and this CVE does not appear in the CISA KEV catalog.
Unauthenticated denial-of-service in Rockwell Automation RSLinx Classic allows a remote attacker to crash the communications service by sending a crafted CIP packet containing an oversized embedded message request. The buffer overflow (CWE-120) causes the RSLinx Classic service to terminate, requiring manual restart to restore industrial device connectivity. In OT/ICS environments where RSLinx Classic bridges engineering workstations to Allen-Bradley PLCs and HMIs, service loss can halt production operations or degrade visibility into live industrial processes. No public exploit or CISA KEV listing confirmed at time of analysis.
Denial-of-service in Rockwell Automation RSLinx Classic allows unauthenticated remote attackers to crash the communication service by sending a specially crafted CIP packet with a manipulated data length field. The root cause is an integer underflow (CWE-191) in the packet length validation routine, causing the service to terminate and requiring a manual restart to recover. No public exploit has been identified at time of analysis and the vulnerability is not listed in CISA KEV, but the zero-barrier network attack vector against a critical ICS communication layer makes this a high-priority remediation target.
Denial-of-service in Rockwell Automation RSLinx Classic allows unauthenticated remote attackers to crash the RSLinx Classic communication service by sending a single crafted CIP packet targeting the Forward Close service. Because RSLinx Classic acts as the primary communication bridge between engineering workstations and Allen-Bradley PLCs, a crash forces a manual service restart and can halt production operations in industrial environments. No public exploit code has been identified at time of analysis, and this CVE is not listed in the CISA Known Exploited Vulnerabilities catalog.
Remote denial-of-service in Rockwell Automation RSLinx Classic allows an unauthenticated network attacker to crash the RSLinx Classic service by sending a single crafted CIP (Common Industrial Protocol) packet, after which the service must be manually restarted to restore communications. The flaw is rooted in an integer-overflow (CWE-190) style mishandling of a malformed packet and carries a CVSS 4.0 base score of 9.2 driven by high availability impact on both the service and dependent systems. No public exploit has been identified at time of analysis, and the issue is not listed in CISA KEV.
Insecure installation directory permissions in Rockwell Automation ControlFLASH™ expose any local user account to arbitrary code execution by allowing write access to the product's installation folder for the Windows 'Everyone' group. An attacker with low-privileged local access can plant a malicious binary or DLL in the installation directory, which then executes at the permission level of whichever user subsequently launches ControlFLASH - potentially a privileged operator in an OT environment. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog.
Unauthenticated remote denial-of-service in Rockwell Automation CompactLogix 5380 and ControlLogix 5580 industrial controllers allows a network-adjacent attacker to trigger a Major Nonrecoverable Fault (MNRF) by sending a malformed CIP message with an invalid input length, requiring a physical power cycle to restore controller operation. The vulnerability is rooted in CWE-119 (improper buffer bounds restriction) during CIP message processing on EtherNet/IP-accessible PLCs. No public exploit code or active exploitation has been identified at the time of this analysis, but the zero-prerequisite network attack surface on safety-critical industrial hardware makes this a prioritized remediation target for OT security teams.
Privilege escalation in Rockwell Automation FactoryTalk® Activation Manager exposes authenticated local Windows users to full SYSTEM-level access by exploiting visible console windows spawned by the installer's custom actions during installation or repair operations. Any low-privileged user present on the machine during an install or repair sequence can interact with these unprotected, SYSTEM-privileged console windows to launch an unrestricted command shell. No public exploit has been identified at time of analysis, but the attack technique - console window hijacking during elevated installer operations - is a well-documented Windows privilege escalation class requiring minimal skill once the precondition is met.
Rockwell Automation's ArmorStart LT industrial motor control device contains a denial-of-service flaw in its embedded web server, exploitable by sending a crafted HTTP PUT request with no authentication or special preconditions. The root cause (CWE-770) is improper resource throttling during HTTP PUT processing, which causes the web server to become unavailable. No public exploit code has been identified and the vulnerability is not listed in CISA KEV, but the unauthenticated network attack surface in an OT/ICS context makes this a material operational risk wherever the device's web interface is reachable.
Remote denial-of-service in the Rockwell Automation FLEX 5000 EtherNet/IP adapter allows an unauthenticated network attacker to crash the module by sending a crafted CIP (Common Industrial Protocol) packet, halting the adapter and its associated I/O until a manual power cycle restores operation.

No public exploit identified at time of analysis, and the CVE is not listed in CISA KEV, so there is no confirmed active exploitation.
Local arbitrary code execution in Rockwell Automation Studio 5000 Logix Designer arises because the External Tools configuration stores executable paths that contain spaces without quoting (CWE-428). A low-privileged local user who can write a malicious binary into an earlier segment of the resolved search path can have Windows execute it in place of the intended tool, running code with the privileges of the operator using the application. No public exploit has been identified at time of analysis, and the flaw is not listed in CISA KEV; the CVSS 4.0 score is 7.3 (High), tempered by local access, high attack complexity, a present attack requirement, and required active user interaction.
Certificate revocation bypass in Rockwell Automation ControlLogix 5580, CompactLogix 5380, GuardLogix 5580, Compact GuardLogix 5380, and 1756-EN4TR (EN4) communication modules allows a network-based attacker to establish a CIP Security connection using a certificate whose issuing intermediate CA has been revoked. Because the controller does not honor the Certificate Revocation List (CRL) for a revoked intermediate, an attacker holding such a certificate can present it as trusted and bypass CIP Security authentication. No public exploit identified at time of analysis; the vendor rates it CVSS 4.0 8.2 (High).
Local authenticated code execution in Rockwell Automation Studio 5000 Logix Designer allows any low-privileged authenticated user to tamper with the incorrectly-protected external-tools configuration file (CWE-863) and redirect a configured tool path to a malicious executable. Because the payload runs when a different user later invokes the external tools feature, this is effectively a privilege-crossing RCE against the engineering workstation. There is no public exploit identified at time of analysis and the flaw is not listed in CISA KEV; exploitation is gated by high attack complexity, a specific attack requirement, and required victim interaction (CVSS 4.0 base 7.3).
Arbitrary file write in Rockwell Automation FactoryTalk ThinManager allows an authenticated attacker to abuse a path traversal flaw in the software's API, saving files outside the application's intended directory into restricted system locations. Because CWE-22 file-write primitives on a Windows-based OT management server commonly enable code execution or service disruption, this carries an integrity and availability impact (CVSS 4.0 base 7.2). There is no public exploit identified at time of analysis and the flaw is not listed in CISA KEV.
Stored cross-site scripting in Rockwell Automation FactoryTalk DataMosaix Private Cloud lets a high-privileged authenticated user persist malicious JavaScript through the Workflows configuration, which then executes in the browsers of other users who view the affected page. Successful exploitation can lead to session/account takeover, credential theft, or redirection to attacker-controlled sites. No public exploit identified at time of analysis, and the CVSS 4.0 base score is 8.4 (High).
Authentication bypass in Rockwell Automation FactoryTalk Services Platform (FTSP) lets an authenticated low-privilege user forge JWT tokens during Okta Web Authentication because the application fails to enforce the RSA signing algorithm, permitting the classic 'alg:none' attack. A successful attacker can impersonate any authorized user, reaching system configuration and granting permissions to other systems that FTSP protects. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the alg:none technique is well documented and trivially reproducible once access is obtained.
Denial-of-service in Rockwell Automation 1756-EN2, 1756-EN3, and 1756-ENBT ControlLogix EtherNet/IP communication modules lets an unauthenticated network attacker drop active device connections by sending malformed CIP Implicit (I/O) Connection packets. Because CVSS 4.0 rates only availability impact (VC:N/VI:N/VA:H) and connections recover immediately once the traffic stops, the flaw enables repeatable disruption rather than persistent outage or code execution. No public exploit identified at time of analysis, and the module is not in CISA KEV.
Denial-of-service in the Rockwell Automation 1719-AENTR (and companion 1718-AENTR) EtherNet/IP adapter allows remote attackers to overload the device with a UDP unicast network storm, causing loss of communication that requires a manual power cycle to recover. The CVSS 4.0 score of 8.7 reflects a high availability impact reachable over the network with no privileges or user interaction.

The flaw, reported by Rockwell and tracked as CVE-2026-0647 with a CVSS 4.0 base score of 8.8, has no public exploit identified at time of analysis but is trivially exploitable given no authentication, no user interaction, and low attack complexity over the network.
Denial-of-service in Rockwell Automation 1794-AENTR FLEX I/O EtherNet/IP adapters allows remote unauthenticated attackers to fault the device and sever its connection to associated I/O modules via malformed CIP protocol requests. Recovery requires a manual reset, making this a high-impact availability issue for industrial control environments where uptime is critical. No public exploit identified at time of analysis, but the CVSS 4.0 score of 8.7 reflects the network-reachable, no-privilege attack path against operational technology.
Remote denial of service in Rockwell Automation CompactLogix and ControlLogix programmable automation controllers allows unauthenticated attackers on the network to crash the device by sending a single crafted Common Industrial Protocol (CIP) message. The fault produces a Major Non-Recoverable Fault (MNRF) that requires a full program download to recover, meaning an outage continues until an engineer physically intervenes. No public exploit identified at time of analysis, but the CVSS 4.0 base score of 8.7 and OT impact make this a priority patch for affected plant floors.
Denial-of-service vulnerability in Rockwell Automation FactoryTalk® Historian Machine Edition allows a network-adjacent, high-privilege authenticated attacker to crash the device by sending crafted requests to its web interface, triggering a stack-based buffer overflow (CWE-121) that renders the historian unresponsive. All versions appear affected per the CPE wildcard, and the impact is limited to availability - no confidentiality or integrity compromise is possible. No public exploit code exists and the vulnerability is not listed in CISA KEV at time of analysis.
Remote code execution in Rockwell Automation FactoryTalk® Historian Machine Edition allows an adjacent-network attacker holding low-privilege credentials to fully compromise the historian host via a memory corruption flaw. The root cause is CWE-787 (Out-of-bounds Write), consistent with a buffer overflow in the historian's network-facing service, yielding full confidentiality, integrity, and availability impact on the affected device. No active exploitation has been confirmed in CISA KEV and no public proof-of-concept has been identified at the time of analysis.
Stored cross-site scripting vulnerabilities in Rockwell Automation's ArmorStart® LT distributed motor controller expose industrial operators to persistent script injection via the device's embedded web management interface. Per the CVSS 4.0 AV:N/PR:N vector, unauthenticated remote attackers can inject malicious scripts that are persisted on the device and execute in the browsers of any operator or engineer who subsequently accesses affected pages - enabling session hijacking, credential theft, or display of falsified operational data. No public exploit code has been identified and the vulnerability is absent from CISA KEV, but the ICS context meaningfully elevates practical risk beyond the moderate base score.
Weak bcrypt work factor in Rockwell Automation OTTO Fleet Manager exposes stored password hashes to accelerated offline brute-force attacks when an attacker gains access to an unencrypted system backup. All versions covered by CPE cpe:2.3:a:rockwell_automation:otto®_fleet_manager:* are affected. An adjacent-network attacker with low-level access who obtains a system backup could recover credentials more easily than a properly configured bcrypt implementation would permit, potentially enabling privilege escalation or lateral movement within the OT environment. No public exploit code or CISA KEV listing has been identified at time of analysis.
Path traversal in Rockwell Automation's Studio 5000 Logix Designer allows an attacker who can deliver a crafted ACD project file to write arbitrary files to attacker-controlled locations on an engineer's workstation. The software fails to sanitize or validate embedded filenames during the ACD project-open procedure, enabling path traversal sequences to escape the intended extraction directory and potentially achieve code execution. No public exploit code or CISA KEV listing has been identified at time of analysis, but the ICS context makes targeted file-delivery attacks via spear-phishing or shared project repositories a realistic threat vector.
Denial-of-service in Rockwell Automation CompactLogix/GuardLogix 5380, CompactLogix 5480, and ControlLogix/GuardLogix 5580 controllers running boot firmware below version 1.072 lets a remote unauthenticated attacker write malformed file data that forces the device into a major non-recoverable fault (MNRF), halting the controlled process until manual recovery.

Denial-of-service in Rockwell Automation CompactLogix/GuardLogix 5380, CompactLogix 5480, and ControlLogix/GuardLogix 5580 controllers running boot firmware below version 1.072 lets a remote unauthenticated attacker write malformed file data that forces the device into a major non-recoverable fault (MNRF), halting the controlled process until manual recovery. The flaw carries a CVSS 4.0 base of 9.2 driven purely by availability impact (no data confidentiality or integrity loss) and requires no authentication or user interaction. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Denial-of-service in Rockwell Automation Logix programmable controllers allows a remote unauthenticated attacker to write invalid file data that forces the device into a Major Non-Recoverable Fault (MNRF), halting the industrial process it controls. Rated CVSS 4.0 9.2 (Critical) with availability as the sole impact, the flaw is a CWE-120 buffer overflow reachable over the network with no privileges or user interaction. There is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV, but the low attack complexity makes it a high-priority patch for OT environments.
Remote denial-of-service in Rockwell Automation CompactLogix 5370, Compact GuardLogix 5370, ControlLogix 5570, and GuardLogix 5570 controllers allows a remote user to push a malformed project file that forces the controller into a Major Non-Recoverable Fault (MNRF), halting the controlled process until manual recovery. The CVSS 4.0 score of 9.2 reflects high availability impact on both the controller and the downstream physical process (VA:H/SA:H) with no authentication or user interaction required per the vendor vector. There is no public exploit identified at time of analysis and the flaw is not listed in CISA KEV, but the loss of a safety-rated (GuardLogix) controller makes availability the dominant concern.
Remote denial-of-service in Rockwell Automation's 1734 POINT I/O module allows unauthenticated network attackers to force the module into a faulted state by sending specially crafted CIP (Common Industrial Protocol) messages, halting I/O processing until a manual restart is performed. The CVSS 4.0 base score of 8.7 reflects a high availability impact against a network-reachable OT device with no privileges or user interaction required. There is no public exploit identified at time of analysis, and the flaw is not listed in CISA KEV.
Authorization bypass in Rockwell Automation FactoryTalk Analytics PavilionX allows unauthenticated remote attackers to invoke privileged API endpoints, including user and role management functions, enabling full administrative takeover of the analytics platform. The CVSS 4.0 base score of 8.3 reflects high confidentiality impact with limited integrity and availability effects, and at the time of analysis there is no public exploit identified.
Authentication bypass in Rockwell Automation FactoryTalk Historian Site Edition allows remote attackers to obtain a valid authentication token by repeatedly hammering the login endpoint, exploiting a race condition (CWE-362) in the authentication flow. The flaw carries a CVSS 4.0 score of 9.2 with network attack vector and no privileges required, though successful exploitation depends on winning a timing window (AT:P). No public exploit has been identified at time of analysis, and the issue is not listed in CISA KEV.
Unauthenticated information disclosure in Rockwell Automation CompactLogix 5370 PLCs exposes CIP Connection IDs via the controller's built-in web diagnostics page to any host with network access. The disclosed identifiers can be used by an attacker as a stepping-stone to craft malicious CIP packets, enabling a chained Denial-of-Service attack against active controller connections. No public exploit code or CISA KEV listing has been identified at time of analysis, though the CVSS 4.0 AT:P flag indicates specific network access conditions must be satisfied, which reduces exposure in properly segmented OT environments.
Denial-of-service in Rockwell Automation 1769 CompactLogix 5370 controllers allows remote unauthenticated attackers to induce a minor fault on the PLC by abusing Connection IDs exposed via the device's web interface and sending forged CIP traffic. The CVSS 4.0 base score of 8.7 reflects high availability impact with no authentication or user interaction required, and no public exploit has been identified at time of analysis.
