DescriptionCVE.org

A vulnerability was determined in code-projects Vehicle Showroom Management System 1.0. This issue affects some unknown processing of the file /util/StaffAddingFunction.php. This manipulation of the argument STAFF_ID causes sql injection. The attack can be initiated remotely. The exploit has been publicly disclosed and may be utilized.

AnalysisAI

SQL injection in code-projects Vehicle Showroom Management System 1.0 allows unauthenticated remote attackers to read, modify, or delete database contents via the STAFF_ID parameter in /util/StaffAddingFunction.php. CVSS score of 7.3 (High) reflects network-accessible attack requiring no privileges or user interaction. Publicly available exploit code exists (GitHub POC), significantly lowering exploitation barrier, though no active exploitation confirmed via CISA KEV at time of analysis.

Technical ContextAI

This is a classic SQL injection vulnerability (CWE-89) affecting a PHP-based web application. The affected product, Vehicle Showroom Management System 1.0 by code-projects (CPE 2.3:a:code-projects:vehicle_showroom_management_system:*), fails to properly sanitize the STAFF_ID parameter in the StaffAddingFunction.php endpoint. SQL injection occurs when user-controllable input is concatenated directly into SQL queries without parameterization or escaping, allowing attackers to break out of the intended query structure and inject arbitrary SQL commands. The /util/ directory path suggests this is an administrative or utility function, potentially handling staff management operations. The vulnerability enables manipulation of backend database queries, which in this case provides unauthorized access to confidential data (C:L), ability to modify integrity (I:L), and potentially disrupt availability (A:L) according to the CVSS impact metrics.

RemediationAI

No vendor-released patch identified at time of analysis for code-projects Vehicle Showroom Management System 1.0. The vendor (code-projects.org) has not published a security advisory or patched version according to available references. Immediate mitigation steps: (1) Implement input validation and parameterized queries (prepared statements) for the STAFF_ID parameter in /util/StaffAddingFunction.php using PHP PDO or mysqli prepared statement APIs. (2) Apply web application firewall (WAF) rules to detect and block SQL injection attempts targeting this endpoint, focusing on patterns matching single quotes, SQL keywords (UNION, SELECT, OR, AND), and comment sequences. (3) Restrict network access to /util/ directory to trusted IP ranges or authenticated administrative sessions only via web server configuration (Apache .htaccess or nginx location blocks). (4) Enable database query logging to detect exploitation attempts. (5) Review all other PHP files in the application for similar unsanitized parameter usage, as code quality issues in open-source projects often cluster. (6) Consider migrating to a commercially supported vehicle management platform if vendor responsiveness remains absent.
