PHPGurukul Company Visitor Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in PHPGurukul Company Visitor Management System version 1.0. The issue resides in the '/forgot-password.php' file, where the 'email' parameter is manipulated to inject malicious SQL queries. This vulnerability allows remote attackers to access and manipulate the database, potentially leading to unauthorized data access, data modification or deletion, and disruption of service.

Impact

Exploitation of this vulnerability allows for unauthorized database access, manipulation or deletion of data, and access to sensitive information. It poses a significant threat to system security and business continuity.

Reproduction

The vulnerability can be reproduced by sending a POST request to 'forgot-password.php' with an injected SQL payload in the 'email' parameter. The injection can be crafted to exploit time-based blind SQL injection techniques, such as using 'SLEEP' commands to create 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, minimize database user permissions, and conduct regular security audits.
