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 9.5.0.0 through 9.11.0.0, contains an exposure of sensitive information to an unauthorized actor vulnerability. An unauthenticated remote attacker could potentially exploit this vulnerability, leading to 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 9.5.0.0 through 9.11.0.0 contains an information disclosure vulnerability allowing unauthenticated remote attackers to access sensitive data. The specific mechanism of exposure is not detailed in available sources.

MitigationUpgrade Dell PowerScale OneFS to a version beyond 9.11.0.0 or apply vendor-supplied patches. As an interim measure, restrict network access to the OneFS management interfaces.

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 installed PowerScale OneFS version
    Run the command 'isi version' or 'isi_get_version' from the OneFS CLI to retrieve the currently installed firmware version.
    Affected if The displayed version falls within the affected ranges: 9.5.0.0 to 9.5.1.3, 9.6.0.0 to 9.7.1.9, 9.8.0.0 to 9.10.1.2, or exactly 9.11.0.0
  2. Confirm OneFS management interface accessibility
    Verify network exposure of OneFS management ports (default TCP 8080, 8443 for WebUI) by reviewing firewall rules or using 'isi network interfaces' to list active network configurations.
    Affected if The management interface is reachable from untrusted networks (such as the internet or non-segmented internal networks)
  3. Review access controls on OneFS API endpoints
    Examine the OneFS configuration for any anonymous or unauthenticated access permissions using 'isi auth' commands or the OneFS WebUI under Access > Authentication settings.
    Affected if Anonymous or unauthenticated access is permitted to any API or administrative endpoints

You are affected if your PowerScale OneFS version is within the listed affected ranges AND the management interface is network-accessible without authentication.

Upgrade available Upgrade to 9.5.1.4 / 9.7.1.10 / 9.10.1.3 or later
Fixed in 9.5.1.49.7.1.109.10.1.3
Interim mitigation

Upgrade Dell PowerScale OneFS to a version beyond 9.11.0.0 or apply vendor-supplied patches. As an interim measure, restrict network access to the OneFS management interfaces.

Recommended fix Moderate confidence

Upgrade to OneFS 9.10.1.3 or later (or the latest available stable release) based on your current version branch

  1. 1. Identify the current PowerScale OneFS version by running 'isi version' or checking the web UI
  2. 2. Based on current version, determine the appropriate upgrade target: if running 9.5.0.0-9.5.1.x, upgrade to 9.5.1.4 or later; if running 9.6.0-9.7.1.x, upgrade to 9.7.1.10 or later; if running 9.8.0.0-9.10.1.x, upgrade to 9.10.1.3 or later
  3. 3. Review Dell PowerScale OneFS upgrade documentation and release notes for the target version
  4. 4. Create a backup or snapshot of the cluster before upgrading
  5. 5. Schedule a maintenance window as upgrades require cluster downtime
  6. 6. Download the upgrade ISO from Dell support portal (www.dell.com/support)
  7. 7. Execute the upgrade following Dell's recommended procedure, typically using 'isi upgrade' command or the web UI
  8. 8. Verify the upgrade was successful and the version matches the expected fixed version
Caveat Review OneFS release notes for any breaking changes between your current version and the target version; major version upgrades may require careful planning and compatibility checks
