Doc Text:
A flaw was found in the MeetingBoard web management module. An authenticated administrator on the local network can bypass client-side interface controls by directly modifying the web page Document Object Model (DOM). By circumventing these front-end restrictions, an attacker can invoke restricted interfaces to trigger screenshot operations, resulting in unauthorized information disclosure.

Description OSIDB Bzimport 2026-11-05 22:21:09 UTC 
In Yealink MeetingBoard Pro before 331.320.0.64, the Web management module has a front-end validation bypass vulnerability. An attacker with administrator privileges can modify the page DOM to bypass front-end UI control logic and invoke screenshot-related interfaces, triggering the screenshot function by circumventing front-end interface restrictions. Exploitation can occur only when the attacker has a valid administrator account within the local network.
