DescriptionCVE.org

A vulnerability was determined in projectworlds Car Rental Project 1.0. The affected element is an unknown function of the file /login.php of the component Parameter Handler. This manipulation of the argument uname causes sql injection. Remote exploitation of the attack is possible. The exploit has been publicly disclosed and may be utilized.

AnalysisAI

SQL injection in projectworlds Car Rental Project 1.0 login.php allows unauthenticated remote attackers to bypass authentication, extract sensitive database contents, and potentially modify or delete data via the 'uname' parameter. Publicly available exploit code exists (GitHub POC published), significantly lowering the barrier to exploitation. EPSS data not available, but the combination of network-accessible attack vector, no authentication requirement, and public exploit makes this a practical threat for internet-facing deployments of this vulnerable application.

Technical ContextAI

This vulnerability stems from improper neutralization of special elements in SQL commands (CWE-89), commonly known as SQL injection. The affected component is projectworlds Car Rental Project version 1.0, a PHP-based web application for vehicle rental management. The /login.php endpoint's Parameter Handler fails to properly sanitize the 'uname' input field before incorporating it into SQL queries. This allows attackers to inject malicious SQL syntax that alters query logic, enabling unauthorized database access. Classic SQL injection vectors through login forms typically exploit weak input validation in authentication queries (e.g., SELECT * FROM users WHERE username='[input]'), allowing attackers to manipulate query conditions with payloads like ' OR '1'='1 to bypass authentication or use UNION-based injection to extract data from arbitrary tables. The CPE identifier cpe:2.3:a:projectworlds:car_rental_project:*:*:*:*:*:*:*:* confirms this is a third-party open-source project, likely deployed by small businesses or educational institutions without robust security review processes.

RemediationAI

No vendor-released patch identified at time of analysis. Projectworlds has not published an official security advisory or patched version per available references. Immediate mitigation requires implementing input validation and parameterized queries at the application level. Organizations should apply prepared statements or parameterized queries for all database interactions in /login.php, specifically sanitizing the 'uname' parameter using PHP's PDO prepared statements or MySQLi bind_param() functions. Temporary workaround: implement web application firewall (WAF) rules to detect and block SQL injection patterns targeting /login.php (regex filtering for SQL metacharacters like ', --, UNION, SELECT in username fields), though this provides defense-in-depth rather than fixing root cause. For production systems, consider replacing this application with actively maintained alternatives that follow secure coding practices, as the lack of vendor response suggests abandoned or unmaintained software. Review database permissions to ensure web application accounts operate with least privilege (no DROP, CREATE, or administrative rights). Monitor authentication logs for suspicious login attempts with SQL syntax patterns.
