Summary
Multiple vulnerabilities exist in the Fortinet NGFW component integrated into Siemens RUGGEDCOM APE1808 devices. These include cross-site scripting (CWE-79) in the web management interface and path traversal (CWE-22) that could allow unauthorized file access. The vulnerabilities affect all versions of RUGGEDCOM APE1808 with Fortinet NGFW.
What this means
What could happen
An attacker could inject malicious scripts into web interfaces or access files outside intended directories on the RUGGEDCOM APE1808, potentially compromising device management and network traffic visibility.
Who's at risk
Manufacturing facilities using Siemens RUGGEDCOM APE1808 appliances with Fortinet NGFW components for network security and traffic inspection. This affects organizations relying on these devices for industrial network perimeter defense and secure remote access to critical infrastructure.
How it could be exploited
An attacker with network access to the RUGGEDCOM APE1808's web management interface could inject malicious JavaScript code (CWE-79) or access restricted files (CWE-22) through the Fortinet NGFW component. This requires the victim to interact with the malicious interface or the attacker to chain the vulnerabilities with other attack vectors.
Prerequisites
- Network access to the RUGGEDCOM APE1808 web management interface (typically port 80/443)
- User interaction with a crafted malicious web request (for CWE-79 exploitation)
- No authentication bypass required for initial exploitation
