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 a Path Traversal: '.../...//' 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

A path traversal vulnerability exists in Dell PowerProtect Data Domain's DD OS where the sequence '.../...//' can be used to traverse outside the intended directory boundaries. A low-privileged remote attacker can exploit this to access sensitive files beyond the web root, leading to information exposure.

MitigationApply the vendor-supplied patch for your specific DD OS version. Until patched, restrict network access to the management interface and limit low-privileged user permissions to the minimum required.

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

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

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 command 'ddos -version' or access the admin console to view the system version information
    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 >= 8.3.0.0 through 8.3.0.15, OR >= 8.3.1.0 and < 8.3.1.10
  2. Verify the web management interface is enabled
    Check if the HTTP/HTTPS management interface is active by attempting to access the web UI or reviewing system services with 'system show services'
    Affected if The web management interface is exposed and accessible to the attacker
  3. Confirm low-privileged user accounts exist
    Review user accounts via 'user list' or the admin console to identify non-administrative users with access to the web interface
    Affected if Low-privileged user accounts have access to the web management interface and can send HTTP requests
  4. Test for path traversal if web UI is accessible
    Send an HTTP request containing the sequence '.../...//' followed by a target path (such as '../../etc/passwd') to the web server endpoint
    Affected if The server returns content from files outside the intended web root directory, confirming the vulnerability is exploitable

If the DD OS version is within any of the affected ranges AND the web management interface is accessible to low-privileged users, the environment is vulnerable to path traversal and information exposure.

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 for your specific DD OS version. Until patched, restrict network access to the management interface and limit low-privileged user permissions to the minimum required.

Recommended fix High confidence

DD OS 7.10.1.70+ (LTS2023), 7.13.1.40+ (LTS2024), 8.3.1.10+ (LTS2025), or 8.3.0.16+ (Feature Release)

  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 LTS branch your current version belongs to (LTS2023: 7.10.x, LTS2024: 7.13.x, LTS2025: 8.3.x, or Feature Release 7.7.x-8.3.0.x)
  3. 3. For LTS2023 (7.10.x): Upgrade to DD OS version 7.10.1.70 or later
  4. 4. For LTS2024 (7.13.x): Upgrade to DD OS version 7.13.1.40 or later
  5. 5. For LTS2025 (8.3.1.x): Upgrade to DD OS version 8.3.1.10 or later
  6. 6. For Feature Release (8.3.0.x): Upgrade to DD OS version 8.3.0.16 or later
  7. 7. Download the appropriate DD OS upgrade image from Dell Support (support.dell.com)
  8. 8. Follow standard DD OS upgrade procedures - typically via 'software' CLI command or the Data Domain System Manager
