DoS via improper input validation in RUGGEDCOM ROS TLS certificate upload
CVE-2025-40935 is an improper input validation flaw in the web service of multiple Siemens RUGGEDCOM ROS devices (various models running V5.X prior to V5.10.1). During the TLS certificate upload process, the affected devices do not properly validate attacker-supplied input. An authenticated remote attacker can leverage this to trigger a crash and subsequent reboot of the device, resulting in a temporary denial of service.
