PHPGurukul Men Salon Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in PHPGurukul Men Salon Management System version 1.0. The issue arises in the file '/admin/add-customer-services.php', where the 'sids[]' parameter is processed without proper validation, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, leading to unauthorized database access, data manipulation, and potential disruption of service.

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 its data integrity.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/admin/add-customer-services.php' with the 'sids[]' parameter. The injected SQL payload can be crafted to exploit the vulnerability, such as using a time-based blind SQL injection technique that leverages the 'SLEEP' function to create a delay, indicating successful injection.

Remediation

To address this vulnerability, it is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can further enhance the application's security.
