Code-Projects Restaurant Order System SQL Injection Vulnerability in Payment.php

A critical SQL injection vulnerability has been identified in version 1.0 of the Code-Projects Restaurant Order System. The issue resides in the payment.php file, where the 'tabidNoti' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, leading to unauthorized database access, data manipulation, and potential service disruption.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to interfere with the application's database queries. This could result in unauthorized data access, data modification or deletion, and in some cases, executing administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to 'payment.php' with the 'tabidNoti' parameter. The injected SQL payload can be crafted to exploit the time-based blind SQL injection vulnerability, such as by using a payload that includes a SQL injection command followed by a time delay command, like 'SLEEP(5)'. This demonstrates the vulnerability by causing the server to pause for five seconds, indicating that the injection was successful.

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 also help enhance the application's security.
