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 Use of a Broken or Risky Cryptographic Algorithm vulnerability in the DDOS. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to information disclosure. The vulnerability could be leveraged by attackers to conduct phishing attacks that cause users to divulge sensitive information.

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 appliances running DD OS contain a broken or risky cryptographic algorithm vulnerability that could allow unauthenticated remote attackers to disclose sensitive information. The vulnerability affects multiple feature release and LTS versions spanning from 7.7.1.0 through 8.3.1.0. Attackers could exploit this to conduct phishing attacks or intercept sensitive data due to weak cryptographic implementations.

MitigationApply the vendor-supplied patch from Dell that addresses the cryptographic algorithm vulnerability. This is a firmware/OS update for the Data Domain appliance. Review Dell support advisory DSA-2025-099 for specific patch instructions.

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. Confirm Dell PowerProtect Data Domain appliance
    Identify the hardware model or check system documentation to verify the device is a Dell PowerProtect Data Domain appliance running DD OS.
    Affected if Device is not a Dell PowerProtect Data Domain appliance - not affected.
  2. Check DD OS version
    Access the Data Domain management interface or run 'ddos version' command via console/SSH to retrieve the installed DD OS version.
    Affected if Unable to determine version - cannot assess.
  3. Compare version to affected ranges
    Compare the installed DD OS version against: 7.7.1.0 to 7.10.1.69, 7.13.1.0 to 7.13.1.39, 8.3.0.0 to 8.3.0.15, or 8.3.1.0 to 8.3.1.9. Ensure exact version matching (major.minor.maintenance.hotfix).
    Affected if Version falls within any of the listed ranges - potentially affected.
  4. Check for cryptographic services in use
    Review enabled DD OS features and configurations related to encryption, SSL/TLS settings, or data-at-rest encryption. Examine system logs for any cryptographic warnings or errors.
    Affected if Cryptographic services are enabled and version is in affected range - likely affected.

The system is affected if it is a Dell PowerProtect Data Domain appliance running a DD OS version that falls within any of the four affected ranges: 7.7.1.0-7.10.1.69, 7.13.1.0-7.13.1.39, 8.3.0.0-8.3.0.15, or 8.3.1.0-8.3.1.9.

Upgrade available Upgrade to 7.10.1.70 / 7.13.1.40 / 8.3.1.10 or later
Fixed in 7.10.1.707.13.1.408.3.1.10
Interim mitigation

Apply the vendor-supplied patch from Dell that addresses the cryptographic algorithm vulnerability. This is a firmware/OS update for the Data Domain appliance. Review Dell support advisory DSA-2025-099 for specific patch instructions.

Recommended fix High confidence

DD OS 7.10.1.70 or later (for 7.x releases), DD OS 7.13.1.40 or later (for LTS2024), DD OS 8.3.1.10 or later (for 8.x releases)

  1. 1. Identify the current Data Domain Operating System (DD OS) version by running 'ddos-version' or checking the system management interface.
  2. 2. Determine which version range your current DD OS falls into (Feature Release, LTS2023, LTS2024, or LTS2025).
  3. 3. For Feature Release versions >= 7.7.1.0 and < 7.10.1.70: upgrade to DD OS version 7.10.1.70 or later.
  4. 4. For LTS2023 versions >= 7.10.1.0 and < 7.10.1.70: upgrade to DD OS version 7.10.1.70 or later.
  5. 5. For LTS2024 versions >= 7.13.1.0 and < 7.13.1.40: upgrade to DD OS version 7.13.1.40 or later.
  6. 6. For Feature Release versions >= 8.3.0.0 and <= 8.3.0.15: upgrade to DD OS version 8.3.1.10 or later.
  7. 7. For LTS2025 version 8.3.1.0: upgrade to DD OS version 8.3.1.10 or later.
  8. 8. Download the appropriate DD OS upgrade image from Dell Support (support.dell.com) and follow Dell's standard upgrade procedure.
Caveat Follow standard DD OS upgrade procedures; ensure compatibility with existing Data Domain and PowerProtect integrations before upgrading
