CVE-2024-24690Network attack vector

Authenticated service interruption

Published Feb 14, 2024 · Updated Sep 20, 2024

Improper quantity validation in affected Zoom Clients allows remote authenticated users to interrupt service via network access. Zoom has not disclosed the client component, input field, quantity, or invalid operation that triggers the denial of service. A valid account and network reachability are required; published evidence does not establish whether the interruption is a hang or crash.
