Vulnerability AssessmentAI

Risk Assessment The CVSS 6.9 score with vector AV:N/AC:L/PR:N indicates network-accessible, low-complexity exploitation requiring no authentication or user interaction-a high-friction attack surface. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An unauthenticated attacker crafts an HTTP request to /util/UpdateVehicleFunction.php with a malicious VEHICLE_ID parameter containing SQL injection payloads such as ' OR '1'='1 or UNION-based queries. The PHP application concatenates this unsanitized input directly into a SQL query without parameterization, allowing the attacker to extract sensitive vehicle data, modify database records, or potentially execute operating system commands if database permissions allow. …
Remediation Immediate action required: update to a patched version of Vehicle Showroom Management System if available from code-projects. … Detailed patch versions, workarounds, and compensating controls in full report.

Threat intelligence, references, and detailed analysis are available after sign-in.
