Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Dell PowerScale OneFS, versions 9.0.0 up to and including 9.1.0.20, 9.2.1.13, 9.3.0.6, and 9.4.0.3, contain a relative path traversal vulnerability. A low privileged local attacker could potentially exploit this vulnerability, leading to denial of service.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Recommended fix Moderate confidence

9.1.0.21, 9.2.1.14, 9.3.0.7, or 9.4.0.4 (first patched version in respective release branch)

  1. 1. Identify the current installed version of Dell PowerScale OneFS using 'isi version' or through the OneFS web UI under Cluster Management > Overview
  2. 2. Based on the current version, upgrade to the first patched version in that release line: For 9.1.x - upgrade to 9.1.0.21 or later; For 9.2.x - upgrade to 9.2.1.14 or later; For 9.3.x - upgrade to 9.3.0.7 or later; For 9.4.x - upgrade to 9.4.0.4 or later
  3. 3. Download the updated OneFS ISO from the Dell Support website (support.dell.com) using your service tag
  4. 4. Create a OneFS upgrade job via the web UI (Cluster Management > Updates > Upgrade) or CLI using 'isi upgrade' commands
  5. 5. Before upgrading, run pre-upgrade checks using 'isi upgrade precheck' to verify cluster health and compatibility
  6. 6. Execute the upgrade and monitor progress through the OneFS UI or 'isi upgrade status'
  7. 7. After upgrade completes, verify the new version is installed and the vulnerability is resolved
Caveat Standard OneFS upgrade considerations apply - review release notes for any features deprecated or changed between versions; ensure adequate cluster capacity for upgrade process
