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.x through 9.7.0.2 contains an improper handling of unexpected data type vulnerability. A remote unauthenticated 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.

dbcve analysis · moderate confidence

Dell PowerScale OneFS versions 8.2.x through 9.7.0.2 contains an improper handling of unexpected data type vulnerability. A remote unauthenticated attacker can send specially crafted requests containing unexpected data types that the application fails to properly process, causing the service to crash or become unresponsive, resulting in denial of service.

MitigationApply the vendor patch (Dell PowerScale OneFS 9.7.0.3 or later) to remediate this vulnerability. If immediate patching is not feasible, implement network segmentation and restrict unauthenticated access to OneFS management interfaces to reduce attack surface.

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 PowerScale OneFS version
    Run the command 'isi version' or 'isi_status' on the OneFS CLI to retrieve the exact firmware version
    Affected if The displayed version falls within any of these ranges: 8.2.0 to 9.3.0 (inclusive); 9.4.0 to 9.4.0.17; 9.5.0.0 to 9.5.0.7; 9.6.0 to 9.7.0.2
  2. Verify the management interface network exposure
    Check the OneFS network configuration by examining the access zone settings and firewall rules using 'isi network interfaces' and verify which IPs/networks can reach the OneFS admin ports (443, 8080)
    Affected if The OneFS management interfaces (HTTPS admin portal, OneFS REST API) are accessible from untrusted or public networks without authentication restrictions
  3. Confirm whether the service handles unauthenticated requests
    Review the OneFS access zone and authentication configuration using 'isi auth' commands or check if the 'System' zone permits anonymous or unauthenticated API access
    Affected if Unauthenticated requests can reach the OneFS API or web interface without authentication being enforced

You are affected if your OneFS version is 9.7.0.2 or lower within the specified ranges AND your management interfaces are exposed to untrusted networks where an unauthenticated attacker could send crafted requests.

Upgrade available Upgrade to 9.4.0.18 / 9.5.0.8 / 9.7.0.3 or later
Fixed in 9.4.0.189.5.0.89.7.0.3
Interim mitigation

Apply the vendor patch (Dell PowerScale OneFS 9.7.0.3 or later) to remediate this vulnerability. If immediate patching is not feasible, implement network segmentation and restrict unauthenticated access to OneFS management interfaces to reduce attack surface.

Recommended fix High confidence

Upgrade to OneFS 9.7.0.3 or later, or the latest 9.4.0.x (9.4.0.18+), 9.5.0.x (9.5.0.8+), or 9.6.x release based on your current branch

  1. 1. Determine current PowerScale OneFS version using 'isi version' or through the web interface (Cluster Management > Overview)
  2. 2. Schedule a maintenance window for the upgrade (this is a cluster-wide update)
  3. 3. Back up cluster configuration and ensure adequate space for the upgrade
  4. 4. Download the appropriate OneFS ISO image from Dell Support (drivers.dell.com) for the target version
  5. 5. Upload the ISO to the cluster using 'isi clusterscp' or through the web interface
  6. 6. Initiate upgrade using 'isi cluster update' command or through the web interface (Cluster Management > Updates)
  7. 7. Monitor the upgrade progress - this may take several hours depending on cluster size
  8. 8. After upgrade completes, verify the new version using 'isi version'
Caveat Standard OneFS upgrade - review Dell PowerScale OneFS Release Notes for any behavior changes between your current and target version; consider testing in non-production environment first
