Technical details
This vulnerability is a classic unrestricted file upload (CWE-434) affecting the FDS102 web interface. A high-privileged remote attacker can bypass file type validation to upload PHP files to the /uploads/ directory and subsequently request them directly via HTTP to achieve arbitrary code execution. The root cause is improper validation of uploaded file types before storing them in a web-accessible location. Attack precondition: the attacker must have high administrative privileges on the FDS102 system. Exploitation results in full system compromise, including potential access to sensitive railway signaling and track layout information. A fix is available: update to FDS102 v2.14.0 or later.
