Projectworlds Car Rental SQL Injection Vulnerability in Parameter Handler

A SQL injection vulnerability has been identified in the Projectworlds Car Rental Project version 1.0. The issue resides in the book_car.php file, specifically within the Parameter Handler component. The vulnerability is triggered by manipulating the fname parameter, which allows attackers to inject malicious SQL queries. This exploitation can be done remotely, without any authentication requirements.

Impact

Exploitation of this vulnerability allows unauthorized database access, manipulation or deletion of data, leakage of sensitive information, and potentially disruptive actions that could interrupt service.

Reproduction

The vulnerability can be reproduced by sending a POST request to the book_car.php file with a crafted fname 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.
