CVE-2020-8590

Node-name disclosure via incomplete AutoSupport sanitization

Published Feb 8, 2021 · Updated Aug 4, 2024

Information disclosure in NetApp ONTAP before 9.1P18 and 9.3P12 allows local users to discover node names in AutoSupport bundles. The AutoSupport private-data sanitization path leaves node names in generated bundles even when remove-private-data is true. Low-privileged local access is required, and the reported consequence is limited to disclosure of node identifiers.
