CVE-2025-7774Network attack vector

Unauthorized privileged actions via session credential replay

Published Aug 14, 2025 · Updated Aug 14, 2025

Authentication bypass in Rockwell Automation 5032 modules version 1.011 allows remote attackers to perform privileged web actions. The embedded web server accepts intercepted session credentials for three minutes instead of requiring fresh authentication for privileged requests. The attacker must first intercept a valid session credential, and reuse is limited to that three-minute window.
