CVE-2022-35776

Adjacent-network authenticated service interruption

Published Aug 9, 2022 · Updated May 29, 2025

Denial of service in Microsoft Azure Site Recovery 9.0 through 9.49 allows remote authenticated users to interrupt service from an adjacent network. Microsoft has not published the affected component or the wrong resource-consuming operation that triggers the interruption. Reachability requires high-privileged access, and the disclosed consequence is limited to service availability rather than data access or modification.
