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/profile.php file, where the mobilenumber parameter is manipulated to inject malicious SQL queries. This vulnerability can be exploited remotely, potentially affecting other parameters as well.

Impact

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

Reproduction

The vulnerability can be reproduced by sending a POST request to the admin/profile.php file with the fullname, emailid, and mobilenumber parameters. The mobilenumber parameter should include a crafted SQL injection payload that exploits the application's SQL query handling. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

To address this vulnerability, it is recommended to use prepared statements and parameter binding to prevent SQL injection. Input validation and filtering should be implemented to ensure user input conforms to expected formats. Additionally, database user permissions should be minimized, and regular security audits conducted to identify and fix potential vulnerabilities.
