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 8.2.2 and above, contain a password disclosure vulnerability. An unprivileged local attacker could potentially exploit this vulnerability, leading to account take over.

Recommended fix Moderate confidence

Upgrade to the version specified in Dell KB000195815 (one release after 9.3.0 or later fixed release)

  1. 1. Review the vendor security advisory at https://www.dell.com/support/kbdoc/000195815 for the specific fixed release version
  2. 2. Identify the current PowerScale OneFS version by running 'isi version' or via the WebUI under Cluster > Overview
  3. 3. Schedule a maintenance window for the upgrade, ensuring all critical data is backed up
  4. 4. Download the firmware/ISO for the fixed OneFS release from Dell Support
  5. 5. Follow the standard OneFS upgrade procedure: create a snapshot/backup, pause SMB connections if needed, run the upgrade via WebUI or CLI (isi升级)
  6. 6. Verify the upgrade completed successfully and confirm the new version is running
  7. 7. Test that the password disclosure vulnerability is no longer reproducible
Caveat Review Dell upgrade documentation for any compatibility notes between your current version and the target fixed release
