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.x through 9.8.0.x contain an uncontrolled resource consumption vulnerability. A low privilege remote 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 9.5.0.x through 9.8.0.x contain an uncontrolled resource consumption vulnerability. A low-privilege remote attacker can exploit this to exhaust system resources (likely memory, CPU, or file descriptors) and cause denial of service.

MitigationApply the vendor patch or upgrade to a fixed OneFS version beyond 9.8.0.x. If immediate patching is not feasible, implement network-level access controls to limit exposure to untrusted users and monitor for anomalous resource usage.

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 OneFS version
    Run 'isi version' or access the OneFS web UI dashboard to retrieve the installed firmware version
    Affected if Version is 9.8.0.0 or falls between 9.5.0.0 and 9.7.1.2 inclusive
  2. Confirm product model
    Verify the system is Dell PowerScale OneFS (not another Dell storage product) using 'isi hardware' or the web UI system information
    Affected if Product is PowerScale OneFS and version check from step 1 shows affected range
  3. Check network exposure
    Review firewall rules or access lists that control which IP addresses can reach OneFS management interfaces and SMB/NFS ports
    Affected if System accepts remote connections from untrusted networks without restriction
  4. Audit user privileges
    Review user accounts in OneFS (via 'isi auth' or web UI) to identify low-privilege accounts that could trigger the vulnerability
    Affected if Low-privilege users exist who can authenticate to the system remotely

The environment is affected if PowerScale OneFS version is 9.8.0.0 or any version from 9.5.0.0 through 9.7.1.2, and the system is accessible to untrusted remote users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to 9.7.1.3 or later
Fixed in 9.7.1.3
Interim mitigation

Apply the vendor patch or upgrade to a fixed OneFS version beyond 9.8.0.x. If immediate patching is not feasible, implement network-level access controls to limit exposure to untrusted users and monitor for anomalous resource usage.

Recommended fix Moderate confidence

OneFS 9.7.1.3 or later (9.8.x fixed release)

  1. 1. Identify the current PowerScale OneFS version using 'isi version' or through the web administration interface.
  2. 2. Schedule a maintenance window for the upgrade process.
  3. 3. Create a complete backup of the cluster configuration and data.
  4. 4. Download the patched OneFS version (9.7.1.3 or later, or the appropriate 9.8.x fix) from Dell Support at support.dell.com.
  5. 5. Follow Dell's standard OneFS upgrade procedure: use 'isi upgrade' command or the OneFS web interface to initiate the upgrade.
  6. 6. Verify the upgrade completed successfully by checking 'isi version' shows the new version.
  7. 7. Confirm the vulnerability is resolved by verifying the build version matches the fixed release.
Caveat Standard OneFS upgrade risks apply - ensure valid cluster backup and follow Dell upgrade documentation; some prior versions may require intermediate upgrades
