CVE-2024-45422Network attack vector

Unauthenticated service interruption

Published Nov 19, 2024 · Updated Nov 20, 2024

Improper input validation in Zoom Workplace Apps and Meeting SDK before 6.2.0 allows remote attackers to interrupt service. Zoom has not disclosed the affected parser, message type, or validation error that processes malformed network input. Network access without authentication is sufficient; the disclosed consequence is denial of service, but whether it causes a hang or crash is unspecified.
