Code-Projects Online Event Judging System SQL Injection Vulnerability in edit_judge.php

A SQL injection vulnerability has been identified in version 1.0 of the Code-Projects Online Event Judging System. The issue arises in the edit_judge.php file, where the judge_id parameter is manipulated, allowing attackers to inject malicious SQL queries.

Impact

Exploitation of this vulnerability allows for unauthorized database access, manipulation of data, and potential disruption of services.

Reproduction

The vulnerability can be reproduced by sending a POST request to the edit_judge.php file with a crafted judge_id parameter. The injected SQL payload can be designed to exploit time-based blind SQL injection techniques, such as using the SQL SLEEP function to create a delay as a proof of concept.
