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 PowerProtect Data Domain with Data Domain Operating System (DD OS) of Feature Release versions 7.7.1.0 through 8.5, LTS2025 release version 8.3.1.0 through 8.3.1.20, LTS2024 release versions 7.13.1.0 through 7.13.1.50, contain a command injection vulnerability. A high privileged attacker with local access could potentially exploit this vulnerability to gain root-level access.

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

Command injection vulnerability in Dell PowerProtect Data Domain's Data Domain Operating System (DD OS) allows a high-privileged local attacker to inject arbitrary commands and escalate to root-level access. The vulnerability affects multiple feature release and LTS versions.

MitigationApply vendor patches for the affected DD OS versions. Restrict local access to trusted, privileged users only and monitor for suspicious local activity.

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 product
    Run 'system show model' or check the appliance model number to determine if it is a Dell PowerProtect DP Series Appliance or a Dell Data Domain system running DD OS
    Affected if Product is Dell PowerProtect DP Series Appliance or Dell Data Domain Operating System
  2. Check DD OS version
    Run 'version' or 'show version' command on the DD OS CLI to obtain the exact firmware version number
    Affected if Version cannot be determined or is not displayed
  3. Compare PowerProtect DP Appliance version
    If running PowerProtect DP Series Appliance, run 'software show' or check the management interface for the installed version. Affected if version < 2.7.9
    Affected if PowerProtect DP Series Appliance version is below 2.7.9
  4. Compare DD OS version against first range
    If running DD OS, check if version is >= 7.7.1.0 and < 7.13.1.50. Run 'version' to see the full version string
    Affected if DD OS version falls within >= 7.7.1.0 and < 7.13.1.50
  5. Compare DD OS version against second range
    Check if DD OS version is >= 8.3.1.0 and < 8.3.1.20
    Affected if DD OS version falls within >= 8.3.1.0 and < 8.3.1.20
  6. Compare DD OS version against third range
    Check if DD OS version is >= 8.4.0.0 and < 8.6.0.0
    Affected if DD OS version falls within >= 8.4.0.0 and < 8.6.0.0

The environment is affected if it is a Dell PowerProtect DP Series Appliance below version 2.7.9, or Dell Data Domain Operating System with a version matching any of the three affected ranges (7.7.1.0-7.13.1.49, 8.3.1.0-8.3.1.19, or 8.4.0.0-8.5.9.x).

Apply vendor patches for the affected DD OS versions. Restrict local access to trusted, privileged users only and monitor for suspicious local activity.

Recommended fix High confidence

PowerProtect DP Series Appliance: upgrade to 2.7.9 or later; DD OS: upgrade to 7.13.1.50, 8.3.1.20, or 8.6.0.0 (depending on current branch)

  1. 1. Identify the currently installed PowerProtect DP Series Appliance or Data Domain Operating System version using the system management interface or CLI.
  2. 2. For PowerProtect DP Series Appliance: If version is below 2.7.9, plan upgrade to version 2.7.9 or later.
  3. 3. For Data Domain Operating System: Determine which version range applies (7.7.x, 8.3.x, or 8.4.x-8.5.x) and upgrade to the corresponding fixed version: 7.13.1.50, 8.3.1.20, or 8.6.0.0 respectively.
  4. 4. Review Dell upgrade documentation and release notes for the target version before initiating upgrade.
  5. 5. Schedule maintenance window as upgrades may require system downtime.
  6. 6. Perform backup of critical configuration data as a precautionary measure.
  7. 7. Execute upgrade following Dell-provided procedures for the specific appliance/model.
  8. 8. Verify successful installation by confirming the new version post-upgrade.
Caveat Standard upgrade risks apply - review Dell release notes for any configuration or compatibility changes in the target version
