CVE-2024-27241Network attack vector

Authenticated service interruption via undisclosed input flaw

Published Jul 15, 2024 · Updated Aug 2, 2024

Improper input validation in Zoom Apps and SDKs before 6.0.0, and VDI before 5.17.13, allows remote authenticated users to interrupt service. Zoom has not disclosed the affected component, rejected input, or operation that mishandles it, leaving the concrete failure mechanism unspecified. Exploitation requires an authenticated Zoom user with network reachability, and the documented consequence is limited to loss of availability rather than data access or modification.
