Remote shell via unintended cross-VLAN service exposure
Published Jul 9, 2024 · Updated Aug 27, 2025
Incorrect privilege assignment in Siemens RUGGEDCOM ROS before 5.9.0 allows remote authenticated users to create a remote shell. With IP forwarding enabled, the firmware exposes remote services in non-managed VLANs even when those services were not intentionally activated. Exploitation requires high privileges and the non-default IP-forwarding configuration, but grants control of the appliance.
