CVE-2025-7971

Code execution via unsafe environment-variable path

Published Aug 14, 2025 · Updated Aug 14, 2025

Improper input validation in Rockwell Automation Studio 5000 Logix Designer 36.00.02 allows local users to execute code. The application unsafely consumes an environment-variable path; a path lacking a valid file crashes the process, while a crafted path enables code execution. Exploitation requires local low-privileged access and passive user interaction; Rockwell has not disclosed the variable, executable, or code path involved.
