Attack Chain

1. An attacker identifies a Vehicle Showroom Management System 1.0 instance exposed to the internet.
2. The attacker crafts a malicious HTTP request targeting /util/VehicleDetailsFunction.php.
3. The request includes a modified VEHICLE_ID parameter containing SQL injection payloads.
4. The application fails to properly sanitize the VEHICLE_ID input.
5. The unsanitized input is directly incorporated into an SQL query.
6. The injected SQL code is executed against the database.
7. The attacker retrieves sensitive information from the database, such as user credentials, vehicle details, or financial records.
8. The attacker uses the obtained credentials to gain unauthorized access to the system or exfiltrates the data.

Impact

Successful exploitation of CVE-2026-6036 allows an attacker to execute arbitrary SQL queries against the Vehicle Showroom Management System’s database. This could lead to the disclosure of sensitive customer information, modification of vehicle inventory data, or even complete compromise of the system. The vulnerability could result in significant financial losses, reputational damage, and legal liabilities for affected organizations. While the number of affected installations is unknown, Vehicle Showroom Management Systems are commonly used by dealerships and automotive businesses, making them attractive targets.

Recommendation

• Apply appropriate input validation and sanitization techniques to the VEHICLE_ID parameter in /util/VehicleDetailsFunction.php to prevent SQL injection attacks.
• Deploy the Sigma rule Detect Suspicious SQL Injection Attempts in Vehicle Showroom Management System to your SIEM and tune for your environment to detect exploitation attempts.
• Monitor web server logs for suspicious requests targeting /util/VehicleDetailsFunction.php with potentially malicious VEHICLE_ID parameters.
• Consider using a Web Application Firewall (WAF) to filter out malicious requests targeting the vulnerable endpoint.
