Code-Projects Hostel Management System SQL Injection Vulnerability in Allocated Rooms File

A critical SQL injection vulnerability has been identified in version 1.0 of the Code-Projects Hostel Management System. The issue resides in the '/allocated_rooms.php' file, where the 'search_box' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely without any authentication, posing a significant risk to database security and data integrity.

Impact

Exploitation of this vulnerability allows unauthorized access to the database, manipulation of data, leakage of sensitive information, and potential disruption of services.

Reproduction

The vulnerability can be reproduced by sending a POST request to 'allocated_rooms.php' with a crafted 'search_box' parameter that includes malicious SQL payloads. Several types of SQL injection techniques can be used, such as boolean-based blind, error-based, time-based blind, and UNION query injections. This can be done using tools like sqlmap.

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.
