Impact

The CVSS 4.0 vector (AV:N/AC:L/PR:N) confirms network-accessible, unauthenticated attack with low complexity. CVSS impact ratings (VC:L/VI:L/VA:L) reflect limited confidentiality and integrity damage per the vendor scoring, though SQL injection typically poses broader database compromise risk depending on database permissions and data sensitivity. The presence of publicly available exploit code (POC=YES) combined with remote network accessibility significantly elevates practical risk despite the moderate CVSS score. The absence of CEI (Changes Exploitability Indicator) values and lack of CISA KEV confirmation suggest this is not yet confirmed as actively exploited in the wild, but the public POC availability means exploitation is probable. Organizations running Car Rental Project 1.0 face immediate risk of database enumeration, unauthorized data access, and potential data modification if database user permissions are broadly assigned.

Exploit ScenarioDerived

An unauthenticated attacker discovers the Car Rental Project instance and crafts a malicious request to /book_car.php with a SQL injection payload in the fname parameter (e.g., fname=test' OR '1'='1). Due to the absence of input validation, the injected SQL is executed against the backend database. The attacker can extract sensitive customer data, booking details, or administrative credentials. With publicly available exploit code documented at https://github.com/eqiya17/collection-of-vulnerabilities/issues/12, an attacker with minimal technical skill can rapidly reproduce and weaponize this vulnerability at scale.

AnalysisAIv1 – Apr 06, 2026

SQL injection in projectworlds Car Rental Project 1.0 allows remote attackers to execute arbitrary SQL queries via the fname parameter in /book_car.php, enabling unauthenticated database manipulation with potential confidentiality and integrity impact. The vulnerability has publicly available exploit code and a moderate CVSS score of 6.9, indicating practical exploitability despite low attack complexity.

RemediationAI

Immediate remediation requires upgrading to a patched version of projectworlds Car Rental Project if available from the vendor; however, no vendor-released patch version is independently confirmed in current advisory data. As an interim mitigation, apply input validation and parameterized queries (prepared statements) to the /book_car.php file, specifically sanitizing the fname parameter before use in any SQL statement. Implement Web Application Firewall (WAF) rules to block SQL injection patterns in the fname parameter. Consult VulDB submission https://vuldb.com/submit/785863 and monitor the vendor repository for official patch releases. Apply principle of least privilege to database user accounts to limit the scope of data accessible via SQL injection exploitation.

Technical ContextAI · show details

The vulnerability exists in the Parameter Handler component of the Car Rental Project, a PHP-based web application. The root cause is improper input validation and parameterization in the SQL query construction for the /book_car.php endpoint. CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) indicates that user-supplied input from the fname parameter is incorporated directly into SQL statements without adequate escaping, type casting, or prepared statement use. The affected product spans the Car Rental Project codebase (CPE: cpe:2.3:a:projectworlds:car_rental_project:*:*:*:*:*:*:*:*), suggesting all versions prior to any vendor-issued patch are vulnerable.
