CVE-2023-32488Network attack vector

Unauthenticated information disclosure through NFS

Published Aug 16, 2023 · Updated Oct 8, 2024

Information disclosure in NFS in affected Dell PowerScale OneFS releases allows remote attackers to read sensitive data over the network. Dell has not published the specific NFS code path or incorrect operation that exposes the information. Unauthenticated NFS access is sufficient; affected releases are 9.2.1.0 through 9.2.1.22, 9.4.0.0 through 9.4.0.13, and 9.5.0.0 through 9.5.0.3, with confidentiality loss only.
