RUGGEDCOM ROX MX5000: Client-Side Enforcement of Server-Side Security

Published Updated By the CyberSecBulletin desk

CVE-2025-40591 is a high-severity client-side enforcement of server-side security vulnerability in RUGGEDCOM ROX MX5000 from Siemens, with a CVSS 3.1 base score of 7.7 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version V2.16.5 as the first without the flaw, so updating RUGGEDCOM ROX MX5000 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.71% chance of exploitation within 30 days, higher than 54% of scored CVEs.

Next patch cycle

Official description

A vulnerability has been identified in RUGGEDCOM ROX MX5000 (All versions < V2.16.5), RUGGEDCOM ROX MX5000RE (All versions < V2.16.5), RUGGEDCOM ROX RX1400 (All versions < V2.16.5), RUGGEDCOM ROX RX1500 (All versions < V2.16.5), RUGGEDCOM ROX RX1501 (All versions < V2.16.5), RUGGEDCOM ROX RX1510 (All versions < V2.16.5), RUGGEDCOM ROX RX1511 (All versions < V2.16.5), RUGGEDCOM ROX RX1512 (All versions < V2.16.5), RUGGEDCOM ROX RX1524 (All versions < V2.16.5), RUGGEDCOM ROX RX1536 (All versions < V2.16.5), RUGGEDCOM ROX RX5000 (All versions < V2.16.5). The 'Log Viewers' tool in the web interface of affected devices is vulnerable to command injection due to missing server side input sanitation. This could allow an authenticated remote attacker to execute the 'tail' command with root privileges and disclose contents of all files in the filesystem.

The underlying weakness: Client-Side Enforcement of Server-Side Security

The product includes a server that relies on the client to implement a protection mechanism that is intended to protect the server.

How developers prevent this class of flaw

  • If some degree of trust is required between the two entities, then use integrity checking and strong authentication to ensure that the inputs are coming from a trusted source. Design the product so that this trust is managed in a centralized fashion, especially if there are complex or numerous communication channels, in order to reduce the risks that the implementer will mistakenly omit a check in a single code path.
