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, 8.2.x - 9.5.0.x, contains an elevation of privilege vulnerability. A low privileged local attacker could potentially exploit this vulnerability, leading to denial of service, code execution and information disclosure.

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.

dbcve analysis · moderate confidence

Dell PowerScale OneFS versions 8.2.x through 9.5.0.x contain a local privilege escalation vulnerability that allows a low-privileged local attacker to gain elevated privileges, potentially leading to code execution, denial of service, or information disclosure.

MitigationApply the vendor-supplied patch for Dell PowerScale OneFS to address the privilege escalation vulnerability. Restrict local access to trusted personnel and monitor for unauthorized privilege escalation attempts.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check PowerScale OneFS version
    Run the command `isi version` or `isi_status` on the OneFS CLI to retrieve the installed OneFS version number
    Affected if The version falls within these ranges: 9.2.1.0 through 9.2.1.22, 9.4.0.0 through 9.4.0.13, or 9.5.0.0 through 9.5.0.3
  2. Verify the full version string
    Run `isi version -d` or check /var/emc/isi_version to get the complete version build string and confirm the exact minor version
    Affected if The version output shows any build within the affected ranges listed above
  3. Confirm local user access exists
    Check if non-administrator local user accounts exist on the system using `isi auth users list` or by reviewing local authentication configuration
    Affected if There are any non-root local user accounts configured on the OneFS cluster
  4. Identify privilege level of standard users
    Review user privileges by running `isi auth users view <username>` for standard users to confirm they have low-privileged roles (such as roles below Administrator or Cluster Admin)
    Affected if Standard local users with limited roles exist on the system and the OneFS version is within the affected ranges
  5. Check for recent privilege escalation indicators
    Review system audit logs in /var/log/audit/ or use `isi audit` commands to look for unexpected privilege changes or new administrative sessions
    Affected if Audit logs show unexpected role changes or privilege escalation events that correlate with local user activity

A user is affected if their PowerScale OneFS version falls within 9.2.1.0-9.2.1.22, 9.4.0.0-9.4.0.13, or 9.5.0.0-9.5.0.3 AND they have local user accounts on the system.

Upgrade available Upgrade to a release after 9.5.0.3
Interim mitigation

Apply the vendor-supplied patch for Dell PowerScale OneFS to address the privilege escalation vulnerability. Restrict local access to trusted personnel and monitor for unauthorized privilege escalation attempts.

Recommended fix Moderate confidence

Upgrade to OneFS 9.2.1.23+ (for 9.2.1.x line), 9.4.0.14+ (for 9.4.0.x line), or 9.5.0.4+ (for 9.5.0.x line). Best practice is to upgrade to the latest available stable release in your supported branch.

  1. 1. Identify the current PowerScale OneFS version by running 'isi version' or checking the OneFS web interface under Cluster > Management > Cluster Identity.
  2. 2. Based on the current version, determine the minimum fixed release to upgrade to: For 9.2.1.x line, upgrade to 9.2.1.23 or later; For 9.4.0.x line, upgrade to 9.4.0.14 or later; For 9.5.0.x line, upgrade to 9.5.0.4 or later.
  3. 3. Review Dell PowerScale OneFS upgrade documentation and compatibility matrix at support.dell.com.
  4. 4. Create a complete cluster backup/snapshot before initiating the upgrade.
  5. 5. Plan for a maintenance window as the upgrade will require cluster downtime.
  6. 6. Download the appropriate OneFS iso/image from Dell support portal for the target fixed version.
  7. 7. Initiate the upgrade using 'isi upgrade' command or OneFS web interface under Platform > Upgrade.
  8. 8. Monitor the upgrade process and verify cluster health post-upgrade using 'isi status' and 'isi health'.
Caveat Review OneFS release notes for any feature changes or migration considerations before upgrading; some upgrades may require sequential intermediate releases.
