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 Feature Release versions 7.7.1.0 through 8.6.0.0 and version 8.7.0.0, LTS2025 release versions 8.3.1.0 through 8.3.1.20, and LTS2024 release versions 7.13.1.0 through 7.13.1.60 contain an improper neutralization of argument delimiters in a command ('argument injection') vulnerability. A high privileged attacker with local 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

Argument injection vulnerability in Dell PowerProtect Data Domain allows a high-privileged local attacker to inject malicious arguments into commands, achieving arbitrary command execution with root privileges. The flaw exists in how the system handles argument delimiters in command processing.

MitigationApply Dell vendor patches when available; until then, restrict local access to only trusted high-privileged users and monitor for suspicious 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 installed Dell product
    Determine whether the system is running Dell PowerProtect DP Series Appliance or Dell Data Domain Operating System. This can typically be found in system documentation, the product GUI, or by running 'uname -a' or checking /etc/issue for product-specific strings.
    Affected if The system is either a Dell PowerProtect DP Series Appliance or Dell Data Domain Operating System instance.
  2. Determine the installed version
    Retrieve the exact version number of the installed Dell product. For Data Domain, this is typically shown in the system management interface or can be obtained via 'ddboost command' or system info commands. For PowerProtect DP Series, check the appliance management interface or run 'product-version' equivalent commands.
    Affected if The exact version number can be retrieved for comparison.
  3. Compare version against affected ranges
    Compare your installed version against the vulnerable ranges: PowerProtect DP Series Appliance versions < 2.7.9; Data Domain OS versions >= 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 < 8.6.1.10, OR exactly 8.7.0.0.
    Affected if Your installed version falls within any of these affected ranges.

You are affected if your Dell PowerProtect DP Series Appliance is below version 2.7.9, or your Dell Data Domain Operating System version matches any of the vulnerable ranges listed.

Recommended fix High confidence

PowerProtect DP: 2.7.9 or later | Data Domain OS: 7.13.1.70+ / 8.3.1.30+ / 8.6.1.10+ / any version past 8.7.0.0

  1. 1. Identify the current installed version of PowerProtect DP Series Appliance or Data Domain Operating System using the system management interface or CLI
  2. 2. For PowerProtect DP Series Appliance: Schedule a maintenance window and upgrade to version 2.7.9 or later
  3. 3. For Data Domain Operating System: Based on your current version branch, plan an upgrade to the appropriate fixed release:
  4. - If on 7.7.x through 7.13.x: upgrade to 7.13.1.70 or later
  5. - If on 7.14.x through 8.3.x: upgrade to 8.3.1.30 or later
  6. - If on 8.4.x through 8.6.x: upgrade to 8.6.1.10 or later
  7. - If on 8.7.0.0: upgrade to the next available release past 8.7.0.0
  8. 4. Before upgrading, backup all critical data and configuration
Caveat Major version upgrades may require downtime and could have compatibility implications with connected systems; review Dell upgrade guides before proceeding
