CVE-2025-40935Network attack vector

Authenticated device reboot via malformed certificate upload

Published Dec 9, 2025 · Updated Dec 9, 2025

Improper input validation in Siemens RUGGEDCOM ROS devices before 5.10.1 allows remote authenticated users to crash and reboot devices. The web service's TLS certificate upload path fails to validate certificate input before processing it. A valid device account and network access to the web service are required; successful exploitation interrupts service temporarily.
