Summary

Siemens RUGGEDCOM APE1808 devices contain cross-site scripting (CWE-79) and path traversal (CWE-22) vulnerabilities in the web-based management interface. An attacker with valid engineering credentials could exploit these flaws to execute arbitrary code on the device. Siemens is preparing fix versions; no patch is currently available for any version of the APE1808.

What this means
What could happen
An attacker with valid engineering credentials could execute arbitrary code on the APE1808 device through cross-site scripting and path traversal vulnerabilities, potentially disrupting network monitoring, remote access, or industrial process communications that depend on the device.
Who's at risk
Manufacturing facilities and utilities that rely on Siemens RUGGEDCOM APE1808 devices for remote access, secure tunneling, or network monitoring in industrial environments. This impacts any site using the APE1808 for plant communication or process oversight.
How it could be exploited
An attacker with engineer or admin credentials accesses the web-based management interface of the APE1808. By injecting malicious JavaScript (CWE-79) or crafting requests with path traversal sequences (CWE-22), the attacker can execute arbitrary code on the device, compromising its ability to monitor or relay critical industrial traffic.
Prerequisites
  • Valid engineering or administrative credentials for the APE1808 web interface
  • Network access to the APE1808 management port (typically HTTP/HTTPS)
  • User interaction required: an engineer must view a malicious page for XSS to trigger
