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 8.3.0.15, LTS2025 release version 8.3.1.0, LTS2024 release versions 7.13.1.0 through 7.13.1.30, LTS 2023 release versions 7.10.1.0 through 7.10.1.60, 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 arbitrary command execution. Exploitation may allow privilege escalation to root.

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

OS command injection vulnerability in Dell PowerProtect Data Domain systems running DD OS. A high-privileged local attacker can execute arbitrary OS commands, potentially escalating to root privileges. The vulnerability affects multiple Feature Release and LTS versions across a wide range.

MitigationApply vendor patches for the affected DD OS versions (7.7.1.0-8.3.0.15, 8.3.1.0, 7.13.1.0-7.13.1.30, 7.10.1.0-7.10.1.60). Limit local/physical access to affected systems as a compensating control until patching is complete.

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
    Run the command 'system show' or 'hostname' on the DD OS CLI to confirm the device is a Dell PowerProtect Data Domain system.
    Affected if The system is not a Dell Data Domain appliance running DD OS.
  2. Determine the DD OS version
    Execute the command 'version' or 'system show version' on the DD OS CLI to retrieve the installed Data Domain operating system version.
    Affected if Unable to retrieve the DD OS version from the system.
  3. Compare the installed version against the affected ranges
    Compare the retrieved DD OS version to the following vulnerable ranges: 7.7.1.0 through 7.10.1.69, 7.13.1.0 through 7.13.1.39, 8.3.0.0 through 8.3.0.15, and 8.3.1.0 through 8.3.1.9. Check if the version falls within any of these ranges.
    Affected if The installed version is greater than or equal to 7.7.1.0 and less than 7.10.1.70, OR greater than or equal to 7.13.1.0 and less than 7.13.1.40, OR greater than or equal to 8.3.0.0 and less than or equal to 8.3.0.15, OR greater than or equal to 8.3.1.0 and less than 8.3.1.10.
  4. Verify presence of high-privileged local accounts
    Check if local user accounts with administrative privileges exist on the system using 'user' or 'show users' commands in DD OS CLI. This vulnerability requires a high-privileged local attacker to exploit the command injection.
    Affected if Local high-privileged accounts exist on the system.

The system is affected if it is a Dell PowerProtect Data Domain running a DD OS version within the specified vulnerable ranges and has local high-privileged user accounts.

Fixed in 7.10.1.707.13.1.408.3.1.10
Interim mitigation

Apply vendor patches for the affected DD OS versions (7.7.1.0-8.3.0.15, 8.3.1.0, 7.13.1.0-7.13.1.30, 7.10.1.0-7.10.1.60). Limit local/physical access to affected systems as a compensating control until patching is complete.

Recommended fix High confidence

DD OS 7.10.1.70, 7.13.1.40, 8.3.0.16, or 8.3.1.10 (depending on which release branch you are on)

  1. 1. Identify the current Data Domain Operating System (DD OS) version running on the affected system using the 'ddos' CLI or admin console.
  2. 2. Based on the current version, determine the appropriate upgrade path to a fixed release:
  3. - For 7.7.x - 7.10.0.x: Upgrade to 7.10.1.70 or later
  4. - For 7.10.1.x (< 7.10.1.70): Upgrade to 7.10.1.70 or later
  5. - For 7.13.1.x (< 7.13.1.40): Upgrade to 7.13.1.40 or later
  6. - For 8.3.0.x (< 8.3.0.16): Upgrade to 8.3.0.16 or later
  7. - For 8.3.1.x (< 8.3.1.10): Upgrade to 8.3.1.10 or later
  8. 3. Download the appropriate DD OS upgrade package from Dell Support (support.dell.com) - ensure the package matches your Data Domain model.
Caveat Standard DD OS upgrade may require downtime; follow Dell's recommended upgrade window and backup procedures
