Attack Chain

1. Attacker identifies a vulnerable instance of Vehicle Showroom Management System 1.0.
2. Attacker crafts a malicious HTTP request targeting /util/RegisterCustomerFunction.php.
3. The crafted request includes a SQL injection payload within the BRANCH_ID parameter.
4. The application fails to properly sanitize the BRANCH_ID input.
5. The unsanitized input is incorporated into a SQL query executed by the application.
6. The SQL injection payload manipulates the query to extract sensitive data or modify database records.
7. The application returns the results of the manipulated query to the attacker.

Impact

Successful exploitation of CVE-2026-6038 can lead to unauthorized access to the Vehicle Showroom Management System’s database. This could result in the disclosure of sensitive customer information (names, addresses, financial details), modification of vehicle inventory data, or even complete compromise of the application’s data integrity. The impact would depend on the level of privileges the application’s database user has and the attacker’s objectives, but it is a high-severity vulnerability due to the ease of exploitation and potential for significant data breach or manipulation.

Recommendation

• Inspect web server logs for suspicious POST requests to /util/RegisterCustomerFunction.php containing unusual characters or SQL keywords in the BRANCH_ID parameter using the Sigma rule “Detect SQL Injection Attempt via BRANCH_ID Parameter”.
• Apply input validation and sanitization to the BRANCH_ID parameter within the /util/RegisterCustomerFunction.php file to prevent SQL injection.
• Monitor database logs for anomalous queries originating from the Vehicle Showroom Management System’s application user.
