Projectworlds Car Rental SQL Injection Vulnerability in Login Component

A SQL injection vulnerability has been identified in Projectworlds Car Rental Project version 1.0. The issue resides in the login.php file, specifically within the Parameter Handler component. The vulnerability arises from inadequate validation of the 'uname' parameter, allowing attackers to inject malicious SQL queries. This exploitation can lead to unauthorized database access, data manipulation, and exposure of sensitive information. Notably, this vulnerability can be exploited remotely without any authentication.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to manipulate database queries. This could result in unauthorized access to the database, modification or deletion of data, and leakage of sensitive information. The vulnerability poses a significant risk to the application's data integrity and security.

Reproduction

The vulnerability can be reproduced by sending a POST request to the login.php file with an injected SQL payload in the uname parameter. 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. 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 mitigate such vulnerabilities.
