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 8.4.0.0, LTS2025 release version 8.3.1.10, LTS2024 release versions 7.13.1.0 through 7.13.1.40, LTS2023 release versions 7.10.1.0 through 7.10.1.70, contain an Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability. A high privileged attacker with local access could potentially exploit this vulnerability, leading to Command execution.

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 PowerProtect Data Domain appliances running DD OS versions 7.7.1.0 through 8.4.0.0 (and specific LTS releases) contain an OS command injection vulnerability (CWE-78). A high-privileged local attacker can inject arbitrary OS commands due to improper neutralization of special elements in the operating system command, potentially achieving full command execution on the affected Data Domain system.

MitigationApply vendor-supplied patches or firmware updates for DD OS once released. Until then, strictly limit local access to trusted high-privileged accounts only and implement enhanced audit logging of administrative command execution.

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 system as a Dell Data Domain appliance
    Check system identification (e.g., hardware model, system inventory, or boot messages) to confirm it is a Dell PowerProtect Data Domain appliance rather than a generic server.
    Affected if The system is not a Dell Data Domain appliance, the vulnerability does not apply.
  2. Determine the installed DD OS version
    Retrieve the Data Domain Operating System version from the system (e.g., via system info command, CLI show command, or management interface).
    Affected if Unable to determine the DD OS version prevents assessment of exposure.
  3. Compare the installed version against affected ranges
    Check if the installed version falls within any of these ranges: 7.7.1.0 to 7.10.1.80 (exclusive of 7.10.1.80), 7.13.1.0 to 7.13.1.50 (exclusive of 7.13.1.50), 8.3.1.0 to 8.3.1.20 (exclusive of 8.3.1.20), or exactly 8.4.0.0.
    Affected if The installed DD OS version matches any of these ranges or the specific version 8.4.0.0, the system falls within the affected population.
  4. Verify presence of high-privileged local accounts
    Review local user accounts with elevated privileges on the Data Domain system (e.g., admin, root, or equivalent privileged DD OS accounts).
    Affected if High-privileged local accounts exist on an affected system, the command injection vulnerability could be exploited by an attacker with access to those accounts.

If the system is a Dell Data Domain appliance running DD OS version 7.7.1.0 through 8.4.0.0 (excluding patched subversions), it is affected by this OS command injection vulnerability.

Upgrade available Upgrade to 7.10.1.80 / 7.13.1.50 / 8.3.1.20 or later
Fixed in 7.10.1.807.13.1.508.3.1.20
Interim mitigation

Apply vendor-supplied patches or firmware updates for DD OS once released. Until then, strictly limit local access to trusted high-privileged accounts only and implement enhanced audit logging of administrative command execution.

Recommended fix Moderate confidence

7.10.1.80 (or later 7.10.1.x) for LTS2023; 7.13.1.50 (or later 7.13.x) for LTS2024; 8.3.1.20 (or later 8.3.x) for LTS2025

  1. 1. Identify the current Data Domain Operating System (DD OS) version using the DD OS CLI command: `version`
  2. 2. Determine which version branch your current installation belongs to (7.7.x-7.9.x, 7.10.x, 7.13.x, 8.3.x, or 8.4.0)
  3. 3. For branch 7.7.1.0-7.9.x: Plan upgrade to 7.10.1.80 or later LTS2023 release (7.10.1.x)
  4. 4. For branch 7.10.1.0-7.10.1.70: Upgrade to 7.10.1.80 or later
  5. 5. For branch 7.13.1.0-7.13.1.40: Upgrade to 7.13.1.50 or later LTS2024 release
  6. 6. For branch 8.3.1.0-8.3.1.10: Upgrade to 8.3.1.20 or later LTS2025 release
  7. 7. For branch 8.4.0.0: Upgrade to the next available patched release (8.3.1.20 or later, or 8.5.x if available)
  8. 8. Before upgrading, review Dell PowerProtect Data Domain release notes for any prerequisites and compatibility requirements
Caveat Review LTS release notes for any configuration or feature changes between versions; test upgrade in non-production environment first
