Attack Chain

1. Attacker identifies a Vehicle Showroom Management System 1.0 instance exposed to the internet.
2. Attacker crafts a malicious HTTP request targeting /util/AddVehicleFunction.php.
3. The crafted request includes a manipulated BRANCH_ID parameter containing SQL injection payload.
4. The application fails to properly sanitize the BRANCH_ID input.
5. The unsanitized BRANCH_ID is incorporated into a SQL query.
6. The database executes the malicious SQL query due to the SQL injection vulnerability.
7. The attacker gains unauthorized access to the database, potentially reading sensitive information.
8. The attacker may further exploit the SQL injection to modify data, escalate privileges, or execute arbitrary code on the server.

Impact

Successful exploitation of this SQL injection vulnerability (CVE-2026-6037) can lead to unauthorized access to sensitive data, including customer information, vehicle details, and financial records. Attackers could potentially modify or delete data, leading to data corruption or loss. In severe cases, attackers may gain complete control of the database server, compromising the entire Vehicle Showroom Management System. Due to the public availability of exploits, the potential impact on unpatched systems is significant.

Recommendation

• Apply appropriate input validation and sanitization techniques to the BRANCH_ID parameter in /util/AddVehicleFunction.php to mitigate the SQL injection vulnerability.
• Deploy the Sigma rule "Detect Vehicle Showroom Management System SQL Injection Attempt" to identify potential exploitation attempts targeting /util/AddVehicleFunction.php.
• Monitor web server logs for suspicious requests containing SQL injection payloads in the BRANCH_ID parameter.
• Consider using a web application firewall (WAF) to filter out malicious requests targeting the vulnerable endpoint.
• Upgrade to a patched version of Vehicle Showroom Management System that addresses CVE-2026-6037 as soon as it becomes available.
