Detection Guidance

To detect this vulnerability, scan your network for devices running the GeoVision GV-LPC2211 V1.13 service on the PTZ control port. Use tools like nmap to check for open ports and services. For example, run 'nmap -p 1-65535 -sV <target_IP>' to identify the service. If the PTZ control service is accessible without authentication, the device is likely vulnerable.
