Authenticated meeting control bypass
Published Aug 11, 2022 · Updated Sep 16, 2024
Improper access control in Zoom On-Premise Meeting Connector MMR before 4.8.129.20220714 allows remote authenticated users to join covertly. The meeting authorization path fails to enforce participant visibility, waiting-room admission, and host-role checks, allowing unauthorized state changes. An authenticated user already authorized to join can bypass visibility and waiting-room controls, assume host status, and disrupt meetings.
