PHPGurukul Curfew e-Pass Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in PHPGurukul's Curfew e-Pass Management System version 1.0. The issue arises in the file '/admin/edit-pass-detail.php', where the 'editid' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, leading to unauthorized database access, data manipulation, and potential leakage of sensitive information.

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 request to '/admin/edit-pass-detail.php' with the 'editid' parameter. The injection can be verified using payloads that exploit boolean-based blind SQL injection, time-based blind SQL injection, or by using UNION-based injection techniques. Tools like sqlmap can automate this process and demonstrate the vulnerability.

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.
