Official Description

A vulnerability has been identified in RUGGEDCOM ROX MX5000 (All versions < V2.17.1), RUGGEDCOM ROX MX5000RE (All versions < V2.17.1), RUGGEDCOM ROX RX1400 (All versions < V2.17.1), RUGGEDCOM ROX RX1500 (All versions < V2.17.1), RUGGEDCOM ROX RX1501 (All versions < V2.17.1), RUGGEDCOM ROX RX1510 (All versions < V2.17.1), RUGGEDCOM ROX RX1511 (All versions < V2.17.1), RUGGEDCOM ROX RX1512 (All versions < V2.17.1), RUGGEDCOM ROX RX1524 (All versions < V2.17.1), RUGGEDCOM ROX RX1536 (All versions < V2.17.1), RUGGEDCOM ROX RX5000 (All versions < V2.17.1). Affected devices do not properly sanitize user-supplied input in the Scheduler functionality of the Web UI, allowing commands to be injected into the task scheduling backend.

This could allow an authenticated remote attacker to execute arbitrary commands with root privileges on the underlying operating system.

Technical Analysis

CVE-2025-40949 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires high privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.1.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
