Unauthenticated code execution via uninitialized NFS resource

Published May 9, 2023 · Updated Jul 10, 2025

Remote code execution in Microsoft Windows Server NFS allows remote attackers to execute arbitrary code via network requests. Microsoft identifies use of an uninitialized resource but has not disclosed the affected function, request field, or erroneous operation. The Server for NFS role must be installed and reachable; no authentication or user interaction is required, and successful exploitation compromises the server.
