PHPGurukul Restaurant Table Booking System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in the PHPGurukul Restaurant Table Booking System version 1.0. The issue resides in the '/admin/password-recovery.php' file, where the 'username' and 'mobileno' parameters are manipulated to inject malicious SQL queries. This vulnerability can be exploited remotely, allowing attackers to gain unauthorized access to the database, leak sensitive information, tamper with data, and potentially disrupt services.

Impact

Exploitation of this vulnerability allows for unauthorized database access, manipulation of data, leakage of sensitive information, and could lead to a complete compromise of the system.

Reproduction

The vulnerability can be reproduced by sending a POST request to the '/admin/password-recovery.php' file with crafted payloads that exploit the SQL injection flaw. The 'username' parameter should be injected with malicious SQL code, while the 'mobileno' parameter can be filled with a standard phone number format. After the injection, the SQL injection can be exploited using techniques such as boolean-based blind, error-based, or time-based blind SQL 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.
