Unauthenticated remote information disclosure
Published Jun 8, 2021 · Updated Aug 3, 2024
Information disclosure in Server for NFS in affected Microsoft Windows releases allows remote attackers to read memory via NFS requests. Microsoft has not published the exact request, function, or code operation that returns unintended data. Exploitation requires network access to the affected NFS component but requires neither authentication nor user interaction; the reported consequence is disclosure only.
