Code-Projects School Fees Payment System SQL Injection Vulnerability in Branch.php

A critical SQL injection vulnerability has been identified in version 1.0 of the Code-Projects School Fees Payment System. The issue resides in the branch.php file, where the 'id' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, leading to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for unauthorized access to the database, manipulation or deletion of data, and access to sensitive information. Such actions pose a significant threat to the overall security of the system and the integrity of its data.

Reproduction

The vulnerability can be reproduced by sending a GET request to branch.php with the action parameter set to 'delete' and the id parameter crafted to include malicious SQL payloads. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection, validate and filter user input, minimize database user permissions, and conduct regular security audits.
