Local disclosure of Clustered Shared Volume data

Published May 10, 2022 · Updated Jan 2, 2025

Information disclosure in Microsoft Windows Server Clustered Shared Volumes allows local users to read protected data from a cluster volume. Microsoft has not published the specific CSV code path, operation, or attacker-controlled input responsible for the disclosure. Exploitation requires low-privilege local access and an affected x64 Windows Server failover cluster using a Cluster Shared Volume; the reported consequence is confidentiality loss only.
