Siemens RUGGEDCOM ROS Devices Protection Mechanism Failure (CVE-2025-41224)

high Tenable OT Security Plugin ID 503755

Synopsis

The remote OT asset is affected by a vulnerability.

Description

The affected products do not properly enforce interface access restrictions when changing from management to non-management interface configurations until a system reboot occurs, despite configuration being saved. This could allow an attacker with network access and credentials to gain access to device through non-management and maintain SSH access to the device until reboot.

This plugin only works with Tenable.ot.
