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 8.4, 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 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the UI. An unauthenticated 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 · moderate confidence

A path traversal vulnerability exists in the web UI of Dell PowerProtect Data Domain systems running DD OS. An unauthenticated remote attacker can exploit improper input validation in the UI to access files outside the intended restricted directory, leading to information exposure.

MitigationApply the vendor-provided patch or update to the affected DD OS versions (7.7.1.0-8.4, 7.13.1.0-7.13.1.30, 7.10.1.0-7.10.1.60) as specified in Dell's security advisory.

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
    Log into the Data Domain system via CLI and run the command 'ddboost show version' or check the system information via the management interface
    Affected if The installed version falls within >= 7.7.1.0 and < 7.10.1.70, OR >= 7.13.1.0 and < 7.13.1.40, OR >= 8.0.0.0 and < 8.5.0.0
  2. Verify the web UI is accessible
    Confirm the Data Domain web management interface (DD MI or DD OS web UI) is enabled and reachable on the network
    Affected if The web UI is exposed and an unauthenticated attacker can send HTTP requests to it
  3. Check for unauthorized file access attempts
    Review web server access logs and audit logs for requests containing path traversal patterns such as '../' sequences or absolute paths outside the web root directory
    Affected if Logs show requests accessing files outside the intended web UI document root directory

If the DD OS version is within any of the affected ranges AND the web UI is accessible, the system is potentially vulnerable to unauthenticated path traversal attacks.

Upgrade available Upgrade to 7.10.1.70 / 7.13.1.40 / 8.5.0.0 or later
Fixed in 7.10.1.707.13.1.408.5.0.0
Interim mitigation

Apply the vendor-provided patch or update to the affected DD OS versions (7.7.1.0-8.4, 7.13.1.0-7.13.1.30, 7.10.1.0-7.10.1.60) as specified in Dell's security advisory.

Recommended fix High confidence

DD OS 7.10.1.70 or later (LTS 2023 branch); DD OS 7.13.1.40 or later (LTS 2024 branch); DD OS 8.5.0.0 or later (Feature Release branch)

  1. 1. Identify the current Data Domain Operating System (DD OS) version by accessing the Data Domain System Manager or using the 'version' command via CLI.
  2. 2. Determine which LTS or Feature Release branch your current version belongs to (LTS 2023: 7.10.x, LTS 2024: 7.13.x, or Feature Release: 7.7.x - 8.4.x).
  3. 3. For systems running version 7.10.1.0 through 7.10.1.60 (LTS 2023), upgrade to version 7.10.1.70 or later.
  4. 4. For systems running version 7.13.1.0 through 7.13.1.30 (LTS 2024), upgrade to version 7.13.1.40 or later.
  5. 5. For systems running version 7.7.1.0 through 8.4.x (Feature Release), upgrade to version 8.5.0.0 or later.
  6. 6. Download the appropriate DD OS upgrade package from the Dell Support site (support.dell.com) using valid credentials.
  7. 7. Review the Data Domain Upgrade Guide for pre-upgrade checklist including backup procedures, downtime requirements, and replication considerations.
  8. 8. Execute the upgrade following Dell's recommended procedures, typically via the 'ddupgrade' command or System Manager GUI.
Caveat Upgrading DD OS may require downtime; verify backup and replication status before proceeding; some upgrade paths may require sequential intermediate upgrades consult Dell upgrade guide
