ICSA-25-226-27: Rockwell Automation ArmorBlock 5000 I/O - Webserver ↗ source

August 14, 2025 CISA ICS Advisory

Summary

Successful exploitation of these vulnerabilities could allow an attacker to predict session numbers or perform privileged actions. CVE-2025-7773: A security issue exists within the 5032 16pt Digital Configurable module's webserver. The webserver's session number increments at an interval that correlates to the last two consecutive login session interval, making it predictable. CVE-2025-7774: A security issue exists within the 5032 16pt Digital Configurable module's webserver. Intercepted session credentials can be used within a three minute timeout window, allowing unauthorized users to perform privileged actions.
