CVE-2026-9127: CWE-863: Incorrect Authorization in Rockwell Automation Studio 5000 Logix Designer
A remote code execution security issue exists within Studio 5000 Logix Designer® due to incorrect authorization on a configuration file. This can allow any authenticated user to modify the paths of external tools configured within the application. If exploited, an attacker could alter the configuration to point to a malicious executable, resulting in arbitrary code execution when any user interacts with the external tools functionality.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-9127) in Studio 5000 Logix Designer arises from improper authorization controls on a configuration file that governs external tool paths. An authenticated user with limited privileges can alter these paths to point to malicious executables. When any user subsequently uses the external tools feature, the malicious code may execute, resulting in remote code execution. The CVSS 4.0 score is 7.3, reflecting high impact and complexity. No official remediation or patch information is available at this time.
Potential Impact
If exploited, this vulnerability allows an authenticated user to execute arbitrary code by modifying external tool paths to malicious executables. This compromises system integrity and could lead to full control over the affected system via the Studio 5000 Logix Designer application. The vulnerability requires authentication and user interaction but has high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to authenticated users and monitor for unauthorized configuration changes related to external tools within Studio 5000 Logix Designer.
