Attack Chain

1. Attacker identifies a vulnerable Vehicle Showroom Management System 1.0 instance exposed on the network.
2. The attacker crafts a malicious HTTP request targeting the /util/Login_check.php endpoint.
3. The attacker injects SQL code into the ID parameter of the HTTP request, bypassing input validation.
4. The web application processes the malicious SQL query without proper sanitization.
5. The injected SQL code is executed against the underlying database.
6. The attacker retrieves sensitive information from the database, such as user credentials or financial records.
7. The attacker may modify database entries, such as altering prices or inventory.
8. The attacker could potentially leverage the SQL injection to gain code execution on the server.

Impact

Successful exploitation of CVE-2026-6165 can lead to a range of severe consequences. An attacker could gain unauthorized access to sensitive customer data, including personally identifiable information (PII) and financial details. Data breaches can result in significant financial losses, reputational damage, and legal liabilities. Furthermore, the ability to modify database contents could lead to manipulated sales figures, altered inventory, or even complete disruption of business operations. The vulnerability’s potential for remote code execution poses the highest risk, allowing attackers to establish a persistent foothold within the organization’s infrastructure.

Recommendation

• Apply appropriate input validation and sanitization techniques to the ID parameter in /util/Login_check.php to prevent SQL injection (CVE-2026-6165).
• Deploy the provided Sigma rule to detect suspicious HTTP requests targeting /util/Login_check.php with potential SQL injection payloads.
• Implement a web application firewall (WAF) to filter malicious traffic and block known SQL injection patterns.
• Regularly audit and patch all software components to address known vulnerabilities.
• Monitor web server logs for unusual activity and potential signs of exploitation.
