XSS vulnerability in Vilar VS-IPC1002 IP cameras

Vilar VS-IPC1002 IP cameras are vulnerable to Reflected XSS (Cross-site Scripting) attacks, because parameters in GET requests sent to /cgi-bin/action endpoint are not sanitized properly, making it possible to target logged in admin users. The vendor did not respond in any way. Only version 1.1.0.18 was tested, other versions might be vulnerable as well.
