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

A SQL injection vulnerability has been identified in version 1.0 of the Code-Projects Online Event Judging System. The issue resides in the '/home.php' file, where the 'main_event' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication.

Impact

Exploitation of this vulnerability allows unauthorized access to the database, where attackers can leak, modify, or delete data. Additionally, it could lead to unauthorized control over the system or cause a disruption of services.

Reproduction

The vulnerability can be reproduced by sending a POST request to 'home.php' with the 'main_event' parameter. The request should include a crafted SQL payload that exploits the application's SQL query handling. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

To address this vulnerability, it is recommended to use prepared statements and parameter binding to prevent SQL injection. Input validation and filtering should be implemented to ensure user input conforms to expected formats. Additionally, database user permissions should be minimized, and regular security audits conducted to identify and fix potential vulnerabilities.
