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 file '/admin/add-subadmin.php', where insufficient input validation of the 'fullname' parameter allows attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, potentially affecting other parameters as well.

Impact

Exploitation of this vulnerability allows attackers to manipulate SQL queries, leading to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/admin/add-subadmin.php' with a crafted 'fullname' parameter that includes malicious SQL payloads. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

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.
