PHPGurukul Old Age Home Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in the Old Age Home Management System version 1.0, specifically within the file /admin/rules.php. The vulnerability arises from inadequate input validation of the 'pagetitle' parameter, allowing attackers to inject malicious SQL queries. This injection is executed without proper sanitization, enabling unauthorized access to the database, data manipulation, and potential disruption of services. Notably, this vulnerability can be exploited remotely without requiring any login or authorization.

Impact

Exploitation of this vulnerability allows attackers to access the database, manipulate or delete data, leak sensitive information, gain control over the system, and disrupt services.

Reproduction

The vulnerability can be reproduced by sending a POST request to /oahms/admin/rules.php with the 'pagetitle' parameter. The injected SQL payload can be crafted to exploit the time-based blind SQL injection vulnerability, such as by using a payload that includes a SQL injection command that causes a delay in the response, indicating successful exploitation.

Remediation

To address this vulnerability, it is recommended to use prepared statements and parameter binding to prevent SQL injection, validate and filter user input to ensure it meets expected formats, and minimize database user permissions to the least required for operations.
