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-9.4.x, contain a command injection vulnerability. An authenticated user having access local shell and having the privilege to gather logs from the cluster could potentially exploit this vulnerability, leading to execute arbitrary commands, denial of service, information disclosure, and data deletion.

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 · high confidence

Dell PowerScale OneFS versions 8.2.x through 9.4.x contain a command injection vulnerability in the log gathering functionality. An authenticated user with local shell access and privileges to gather logs from the cluster can inject arbitrary commands, potentially leading to full system compromise, denial of service, information disclosure, or data deletion.

MitigationApply vendor-supplied patches for PowerScale OneFS. Restrict local shell access and enforce least privilege for log gathering permissions until the patch is applied.

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. Determine installed PowerScale OneFS version
    Run command `isi version` or check `/etc/isi_version` file to identify the exact OneFS version installed on the cluster
    Affected if Version falls within any of these ranges: 9.1.0.0 through 9.1.0.24, 9.2.1.0 through 9.2.1.17, or 9.4.0.0 through 9.4.0.8
  2. Confirm log gathering capability is accessible
    Verify that log collection utilities such as `isi_gather_info` or equivalent log gathering commands exist and are accessible on the system
    Affected if Log gathering functionality is present and executable by authenticated users on the system
  3. Identify users with local shell access
    Review user accounts with shell access by examining `/etc/passwd` or using `isi auth` commands to list users who can access the local command line
    Affected if Any authenticated user account has local shell login capability
  4. Check permissions for log gathering operations
    Use `isi auth` or examine group memberships to determine which users or groups have privileges to execute log collection commands like isi_gather_info
    Affected if Users beyond strict administrative scope have permission to run cluster log gathering commands

The environment is affected if the installed OneFS version is within the vulnerable ranges AND authenticated users have both local shell access AND privileges to execute log gathering functionality.

Upgrade available Upgrade to 9.1.0.25 / 9.2.1.18 / 9.4.0.9 or later
Fixed in 9.1.0.259.2.1.189.4.0.9
Interim mitigation

Apply vendor-supplied patches for PowerScale OneFS. Restrict local shell access and enforce least privilege for log gathering permissions until the patch is applied.

Recommended fix High confidence

Upgrade to OneFS 9.1.0.25 (or later for 9.1.x), 9.2.1.18 (or later for 9.2.x), or 9.4.0.9 (or later for 9.4.x) - preferably the latest available stable release in your branch

  1. 1. Back up all critical data and cluster configuration before initiating any upgrade
  2. 2. Review the Dell PowerScale OneFS upgrade documentation and release notes for the target version
  3. 3. Plan for a maintenance window as the upgrade will require cluster downtime
  4. 4. Download the appropriate OneFS iso image for the fixed version (9.1.0.25, 9.2.1.18, or 9.4.0.9 or later) from Dell Support portal
  5. 5. Initiate the OneFS upgrade using the 'isi upgrade' command or through the WebUI under Cluster Management > Upgrade
  6. 6. Monitor the upgrade process and verify all nodes are successfully upgraded
  7. 7. After upgrade completion, verify the OneFS version matches the expected fixed version using 'isi version'
  8. 8. Test that the vulnerability is no longer exploitable and validate normal cluster operations
Caveat Review Dell release notes for any compatibility changes, feature removals, or migration requirements between your current and target version; some older protocols or configurations may require adjustment
