PHPGurukul Vehicle Parking Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in PHPGurukul Vehicle Parking Management System version 1.13. The issue resides in the '/admin/add-category.php' file, where the 'catename' parameter is manipulated to inject malicious SQL queries. This vulnerability can be exploited remotely, allowing attackers to access and manipulate the database without authorization.

Impact

Exploitation of this vulnerability could lead to unauthorized database access, allowing attackers to modify or delete data, access sensitive information, and potentially disrupt services.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/vpms/admin/add-category.php' with the 'catename' parameter. The request must 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 implement prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be applied to ensure that user input meets expected formats, blocking malicious data. Finally, database user permissions should be minimized, granting only necessary access rights to the database.
