Siemens RUGGEDCOM Products Interface Access Restriction Vulnerability Allowing Unauthorized SSH Access

Vulnerability

A vulnerability exists in multiple RUGGEDCOM products running versions through 5.10.0. The issue arises because these products do not properly enforce access restrictions when switching from management to non-management interface configurations. This flaw allows an attacker with network access and credentials to access the device through a non-management interface and maintain SSH access until the device is rebooted.

Impact

Exploitation of this vulnerability allows for unauthorized access to the device via non-management interfaces, with the ability to maintain SSH access until the device is rebooted.

Remediation

Users are advised to update to RUGGEDCOM ROS version 5.10.0 or later. For products where a fix is not yet available, Siemens recommends deactivating the SSH server if it is not needed, and restricting access to ports 80/tcp, 443/tcp, and 22/tcp to trusted IP addresses only.
