Missing Authentication for Critical Endpoint in Pix-Link LV-WR21Q

Pix-Link LV-WR21Q does not enforce any form of authentication for endpoint /goform/getHomePageInfo. Remote unauthenticated attacker is able to use this endpoint to e.g: retrieve cleartext password to the access point. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version V108_108 was tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.
