Summary
Ruggedcom Rox devices contain an input validation flaw in the Scheduler functionality that allows an authenticated administrator to execute arbitrary OS commands with root privileges. The vulnerability affects RUGGEDCOM ROX MX5000, MX5000RE, RX1400, RX1500, RX1501, RX1510, RX1511, RX1512, RX1524, RX1536, and RX5000 models running firmware versions before 2.17.1.
What this means
What could happen
An authenticated attacker with administrative access could execute arbitrary commands with root privileges on Ruggedcom Rox devices, potentially shutting down network services, altering configurations, or disrupting communications across your industrial network.
Who's at risk
Operators of Siemens Ruggedcom Rox industrial network management devices. These are industrial-grade Ethernet switches and routers used in power generation, oil/gas, water utilities, and manufacturing to provide secure, redundant communication networks. If you use Ruggedcom Rox devices for critical network connectivity (such as control system data or SCADA communications), they are affected.
How it could be exploited
An attacker with valid administrative credentials accesses the Ruggedcom Rox web interface or management console and submits a malicious command through the Scheduler functionality. The input validation flaw allows the attacker to inject OS commands that execute with root privileges, giving full control of the device.
Prerequisites
- Valid administrative credentials for the Ruggedcom Rox device
- Network access to the device management interface (web or administrative port)
- Access to the Scheduler functionality in the management UI
