CVE-2022-37959Network attack vector

Security feature bypass in NDES

Published Sep 13, 2022 · Updated Mar 11, 2025

Security feature bypass in Microsoft Windows Server allows remote authenticated users to bypass NDES security controls via network requests. Microsoft has not published the specific NDES component or operation that mishandles untrusted input, so the mechanism remains undisclosed. The reported impact is limited to bypassing a security feature and exposing protected information; no integrity or availability impact is reported.
