PHPGurukul Art Gallery Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in PHPGurukul Art Gallery Management System version 1.1. The issue resides in the file '/admin/add-art-type.php', where the 'arttype' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, with the injected SQL being executed without proper input validation or sanitization.

Impact

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

Reproduction

The vulnerability can be reproduced by sending a POST request to '/admin/add-art-type.php' with the 'arttype' parameter. The request should be formatted as multipart form data. Injected payloads can be used to test the vulnerability, such as time-based blind SQL injection payloads that exploit the application's database query handling.

Remediation

To address this vulnerability, developers should implement prepared statements and parameter binding to separate SQL code from user input, conduct thorough input validation and filtering, and minimize database user permissions to the least required.
