Attack Chain

1. The attacker identifies an instance of code-projects Vehicle Showroom Management System 1.0.
2. The attacker crafts a malicious HTTP request targeting /util/BookVehicleFunction.php.
3. The attacker injects SQL code into the BRANCH_ID parameter within the HTTP request.
4. The web server passes the crafted SQL query to the underlying database without proper sanitization.
5. The database executes the malicious SQL query.
6. The attacker extracts sensitive information from the database.
7. The attacker may use the extracted credentials to gain further access to the system.
8. The attacker can modify, delete, or exfiltrate data from the database, leading to complete system compromise.

Impact

Successful exploitation of this SQL injection vulnerability (CVE-2026-6149) can have severe consequences. An attacker can gain unauthorized access to the Vehicle Showroom Management System's database, potentially exposing sensitive customer data, vehicle inventory information, and financial records. The vulnerability could lead to data breaches, financial losses, and reputational damage. Given the nature of the application, dealerships and other businesses managing vehicle inventories are the most likely targets.

Recommendation

• Apply the Sigma rule Detect Suspicious BookVehicleFunction.php Access to identify potential exploitation attempts targeting the vulnerable endpoint.
• Inspect web server logs for unusual requests to /util/BookVehicleFunction.php with suspicious characters or SQL keywords in the BRANCH_ID parameter.
• Patch CVE-2026-6149 immediately upon patch availability to mitigate the SQL injection vulnerability.
• Implement proper input validation and sanitization on the BRANCH_ID parameter in /util/BookVehicleFunction.php to prevent future SQL injection attacks.
