Privilege escalation via underauthorized custom URL handling
Published Nov 14, 2023 · Updated Sep 19, 2024
Improper authorization in Zoom Clients before 5.16.0 allows remote authenticated users to escalate privileges via network access. The affected custom URL scheme handler performs inadequate authorization before dispatching a requested action, but Zoom does not disclose the handler or check. Exploitation requires an authenticated user and user interaction; the resulting privilege level and permitted operations are not publicly specified.
