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, 9.0.0.x-9.5.0.x contains an improper handling of insufficient permissions. A low privileged remote attacker could potentially exploit this vulnerability to cause 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 and 9.0.0.x-9.5.0.x contain an improper handling of insufficient permissions vulnerability. A low privileged remote attacker could potentially exploit improper permission validation to gain unauthorized access to sensitive information.

MitigationApply the vendor-provided patch or upgrade to a patched OneFS version. Review user permissions and access controls as part of remediation.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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. Identify the installed OneFS version
    Run the 'isi version' command or check the OneFS web interface dashboard for the current firmware version
    Affected if The version displayed falls within any of these ranges: 8.2.0-8.2.2, 9.2.1-9.2.1.23, 9.4.0-9.4.0.14, or 9.5.0-9.5.0.5
  2. Confirm the exact minor version number
    Use 'isi_get_versions' or access the support dashboard to retrieve the full version string including the build number
    Affected if The full version string shows a version lower than 9.2.1.24, 9.4.0.15, or 9.5.0.6 within the respective branches
  3. Review audit logs for unauthorized access attempts
    Check the OneFS audit logs under /var/log/audit/ or via the platform UI for failed permission checks from low-privileged accounts accessing restricted resources
    Affected if Logs show successful access to sensitive directories or files by accounts lacking explicit permissions for those resources
  4. Verify access control configuration
    Examine the access zone permissions and sharing configurations using 'isi zone' and 'isi smb share' commands to identify any misconfigured ACLs
    Affected if Any share or directory exposes sensitive data to users without proper role-based access control assignments

You are affected if your OneFS version is 8.2.0 through 8.2.2, 9.2.1 through 9.2.1.23, 9.4.0 through 9.4.0.14, or 9.5.0 through 9.5.0.5, and you have low-privileged users who could potentially access restricted information.

Upgrade available Upgrade to 9.2.1.24 / 9.4.0.15 / 9.5.0.6 or later
Fixed in 9.2.1.249.4.0.159.5.0.6
Interim mitigation

Apply the vendor-provided patch or upgrade to a patched OneFS version. Review user permissions and access controls as part of remediation.

Recommended fix Moderate confidence

Upgrade to OneFS 9.2.1.24 (or later 9.2.1.x), 9.4.0.15 (or later 9.4.x), 9.5.0.6 (or later 9.5.x), or a later major version

  1. 1. Identify the current PowerScale OneFS version using 'isi version' or through the web admin console.
  2. 2. Based on the current version, plan upgrade path to the fixed release: For 8.2.x branches, upgrade to 9.2.1.24 or later; For 9.2.1.x, upgrade to 9.2.1.24 or later; For 9.4.x, upgrade to 9.4.0.15 or later; For 9.5.x, upgrade to 9.5.0.6 or later.
  3. 3. Review Dell PowerScale OneFS upgrade prerequisites and compatibility documentation at support.dell.com.
  4. 4. Create a backup of the current cluster configuration.
  5. 5. Schedule a maintenance window as upgrades require brief cluster downtime.
  6. 6. Download the appropriate OneFS iso/image from Dell Support.
  7. 7. Execute the upgrade following Dell's standard OneFS upgrade procedure (typically via 'isi升级' or web admin).
  8. 8. After upgrade completes, verify the new version matches the expected fixed release.
Caveat Upgrades may require cluster downtime; ensure compatibility with existing infrastructure and review Dell's release notes for any behavioral changes in the target version
