CVE-2022-45099

System compromise via weak NDMP password encoding

Published Feb 1, 2023 · Updated Mar 26, 2025

Weak password encoding in Dell Technologies PowerScale OneFS 8.2.x through 9.4.x allows local users to compromise the system via an NDMP password. Dell has not published the encoding algorithm, storage locus, or operation that exposes the NDMP credential. Successful exploitation requires privileged local access and yields credentials sufficient for full system compromise.
