Summary
Yealink MeetingBoard Pro's web management module contains a front-end validation bypass that lets an attacker with administrator privileges on the adjacent local network modify the page to get around interface restrictions and trigger the screenshot function. Exploitation requires a valid administrator account, so it is not reachable without login.
