This vulnerability in projectworlds Car Rental Project 1.0 involves SQL injection via the 'uname' parameter in the /login.php file's Parameter Handler component. An attacker can remotely manipulate this parameter to inject SQL commands, potentially compromising the backend database. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges or user interaction required, and limited confidentiality, integrity, and availability impacts. No vendor patch or advisory is currently available.

Successful exploitation could allow an attacker to execute arbitrary SQL commands on the backend database remotely, potentially leading to unauthorized data access or modification. The impact is rated medium severity based on the CVSS score of 6.9. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider implementing input validation and parameterized queries as temporary mitigations to reduce SQL injection risk.
