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 special elements used in an OS command 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

Dell PowerProtect Data Domain contains an OS command injection vulnerability (CWE-78) where improper neutralization of special elements in input allows a high-privileged attacker with local system access to inject and execute arbitrary OS commands with root privileges. The vulnerability affects multiple version ranges across standard releases and LTS branches.

MitigationApply Dell vendor patches when released; until then, strictly limit local system access to trusted high-privileged administrators only, monitor for suspicious command execution, and consider network segmentation to reduce physical/logical local access exposure.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 installed Data Domain OS version
    Use the system management interface or run the command to display the OS version (e.g., via CLI: `version` or `system show version`)
    Affected if version falls within any of these 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 <= 8.6.1.10, OR exactly 8.7.0.0
  2. Determine if local console access is permitted
    Review system access controls to check whether local/physical console access is enabled for non-administrative or untrusted users
    Affected if local or physical console access is available to any user beyond trusted high-privileged administrators
  3. Verify privilege level of local users
    List local user accounts and their assigned privilege levels using system user management commands
    Affected if any untrusted or low-privilege local user accounts exist with potential console login capability
  4. Review for suspicious root-level processes
    Examine running processes for unexpected commands executing as root (e.g., via process listing commands)
    Affected if unexpected or unauthorized commands are running with root privileges

You are affected if your Data Domain OS version is within the affected ranges AND local system access is possible for users other than trusted high-privileged administrators.

Upgrade available Upgrade to 7.13.1.70 / 8.3.1.30 or later
Fixed in 7.13.1.708.3.1.30
Interim mitigation

Apply Dell vendor patches when released; until then, strictly limit local system access to trusted high-privileged administrators only, monitor for suspicious command execution, and consider network segmentation to reduce physical/logical local access exposure.

Recommended fix Moderate confidence

Upgrade to 7.13.1.70+ (LTS2024), 8.3.1.30+ (LTS2025), or 8.7.1.0+ depending on your current branch

  1. 1. Identify the currently installed Data Domain Operating System version using the admin console or CLI command 'system show version'
  2. 2. Determine which LTS track your current version belongs to (LTS2024 or LTS2025)
  3. 3. For LTS2024 track (7.13.x versions): Upgrade to version 7.13.1.70 or later
  4. 4. For LTS2025 track (8.3.x versions): Upgrade to version 8.3.1.30 or later
  5. 5. For 8.4.x through 8.6.x versions: Upgrade to version 8.7.1.0 or later (or the next available stable release)
  6. 6. For version 8.7.0.0: Upgrade to version 8.7.1.0 or later
  7. 7. Download the upgrade ISO from Dell Support (support.dell.com) using your service tag
  8. 8. Upload the upgrade package via the Data Domain Management Center or CLI
