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, versions 7.7.1.0 through 8.6, LTS2025 release version 8.3.1.0 through 8.3.1.20, LTS2024 release versions 7.13.1.0 through 7.13.1.60 contain an OS command injection vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to arbitrary command execution with root privileges.

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 contains an OS command injection vulnerability in versions 7.7.1.0 through 8.6, LTS2025 (8.3.1.0-8.3.1.20), and LTS2024 (7.13.1.0-7.13.1.60). A high-privileged attacker with remote access can inject arbitrary OS commands that execute with root privileges due to insufficient input sanitization in the affected component.

MitigationApply Dell-supplied patches for this vulnerability; in the interim, restrict administrative access to trusted IP addresses only and monitor for unusual command execution patterns.

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 Dell Data Domain system
    Log into the appliance CLI and run 'system show' or check the system model/metadata to confirm it is a Dell PowerProtect Data Domain or Dell Data Domain appliance
    Affected if The system is not a Dell Data Domain product - this CVE does not apply
  2. Determine the installed Data Domain OS version
    Run the command to display the DDOS version, typically via 'version' or 'system show version' in the appliance CLI
    Affected if The version command fails or returns an unrecognized format indicating a non-DDOS system
  3. Compare installed version against affected ranges
    Check if the installed version falls within: 7.7.1.0 through 7.13.1.69, 7.14.0.0 through 8.3.1.29, or 8.4.0.0 through 8.6.0.x. Use the exact version number returned by the version check.
    Affected if The installed version matches any of the affected ranges (>= 7.7.1.0 and < 7.13.1.70, or >= 7.14.0.0 and < 8.3.1.30, or >= 8.4.0.0 and < 8.6.1.0)
  4. Determine if remote administrative access is enabled
    Review the administrative access configuration via the management interface or CLI commands that show permitted remote access methods and IP restrictions
    Affected if Remote administrative access (such as SSH or web management interfaces exposed to untrusted networks) is enabled and accessible

A user is affected if they run Dell Data Domain Operating System in any of the vulnerable version ranges with remote administrative access exposed to network attackers.

Recommended fix High confidence

PowerProtect Dp Series Appliance: 2.7.9+ | Data Domain OS: 7.13.1.70+ or 8.3.1.30+ or 8.6.1.0+ (depending on current branch)

  1. 1. Identify the current installed version of PowerProtect Data Domain or Data Domain Operating System by running: admin$ version
  2. 2. For PowerProtect Dp Series Appliance: Upgrade to version 2.7.9 or later by downloading the ISO from Dell support portal and following the upgrade procedure in the product documentation
  3. 3. For Data Domain Operating System: If running 7.7.1.0-7.13.1.x, upgrade to version 7.13.1.70 or later
  4. 4. For Data Domain Operating System: If running 7.14.0.0-8.3.1.x, upgrade to version 8.3.1.30 or later
  5. 5. For Data Domain Operating System: If running 8.4.0.0-8.6.1.x, upgrade to version 8.6.1.0 or later
  6. 6. After upgrade, verify the new version is installed: admin$ version
  7. 7. Validate that the vulnerability is resolved by confirming the fixed version is running
Caveat Review Dell upgrade documentation for prerequisites and ensure backup before upgrading; some upgrades may require sequential path through intermediate releases
