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 8.5, LTS2025 release version 8.3.1.0 through 8.3.1.20, LTS2024 release versions 7.13.1.0 through 7.13.1.50, contain an exposure of sensitive information to an unauthorized actor vulnerability. A low privileged attacker with remote access could potentially exploit this vulnerability, leading to information exposure.

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 systems running DD OS contain an information disclosure vulnerability where low-privileged remote users can access sensitive data they should not be authorized to view. The vulnerability exists across multiple Feature Release (7.7.1.0-8.5), LTS2025 (8.3.1.0-8.3.1.20), and LTS2024 (7.13.1.0-7.13.1.50) versions due to improper access controls.

MitigationApply the vendor-supplied patch or upgrade to a fixed DD OS version to remediate the unauthorized information exposure. Review user access permissions and role assignments as part of remediation.

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 DD OS version
    Run 'ddos -v' or 'system show version' on the Data Domain system to obtain the exact DD OS version number
    Affected if The version falls within 7.7.1.0 through 8.5.0.0, or 8.3.1.0 through 8.3.1.20, or 7.13.1.0 through 7.13.1.50
  2. Confirm the product model
    Run 'hardware show' or check the system management interface to confirm the system is a Dell PowerProtect Data Domain or Dell Data Domain appliance
    Affected if The system is a PowerProtect Data Domain or Data Domain model running the affected DD OS versions
  3. Check if remote management access is enabled
    Review the DD OS network configuration using 'network show' or check the management interface settings for enabled remote access protocols (HTTP/HTTPS/SSH)
    Affected if Remote management access is enabled and the system is running an affected DD OS version
  4. Review low-privilege user accounts
    Use 'user list' or access the DD OS user management interface to enumerate existing user accounts and their assigned roles
    Affected if Low-privilege user accounts exist on a system running an affected DD OS version

The environment is affected if it runs Dell PowerProtect Data Domain or Data Domain systems with DD OS versions 7.7.1.0-8.5.0.0, 8.3.1.0-8.3.1.20, or 7.13.1.0-7.13.1.50 and has remote access enabled with low-privilege users present.

Upgrade available Upgrade to a release after 8.5.0.0
Interim mitigation

Apply the vendor-supplied patch or upgrade to a fixed DD OS version to remediate the unauthorized information exposure. Review user access permissions and role assignments as part of remediation.

Recommended fix Moderate confidence

LTS2024: 7.13.1.51 or later; LTS2025: 8.3.1.21 or later; Feature Release: 8.6 or later (or latest available LTS with fix)

  1. 1. Identify the currently installed Data Domain Operating System (DD OS) version using the 'version' command or through the DD Web UI.
  2. 2. Determine which release track the system is on: LTS2024 (7.13.x), LTS2025 (8.3.x), or Feature Release (7.7.x - 8.5.x).
  3. 3. For LTS2024 (7.13.1.0 - 7.13.1.50): Upgrade to LTS2024 release version 7.13.1.51 or later, or migrate to a newer LTS release.
  4. 4. For LTS2025 (8.3.1.0 - 8.3.1.20): Upgrade to LTS2025 release version 8.3.1.21 or later, or migrate to a newer LTS release.
  5. 5. For Feature Release (7.7.1.0 - 8.5.0.0): Upgrade to Feature Release 8.6 or later if available, or migrate to an LTS release with the fix.
  6. 6. After upgrade, verify the new version is not within the affected ranges.
  7. 7. Review DD OS security settings and ensure low-privileged user access controls are properly configured according to Dell best practices.
Caveat Review Dell upgrade documentation for compatibility requirements and ensure backup integrity before upgrading
