SourceCodester Food Ordering Management System SQL Injection Vulnerability in Register Router

A SQL injection vulnerability has been identified in SourceCodester Food Ordering Management System version 1.0. The issue resides in the register-router.php file, where the phone parameter is manipulated to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, leading to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for unauthorized access to the database, manipulation or deletion of data, and access to sensitive information. Such actions can disrupt services and pose a significant threat to overall system security and business operations.

Reproduction

The vulnerability can be reproduced by sending a POST request to the 'register-router.php' file with the 'phone' parameter. The request should include a payload that exploits the SQL injection vulnerability, such as a time-based blind injection that uses the SQL 'SLEEP' function to demonstrate the injection's effectiveness.

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.
