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
A path traversal vulnerability was addressed in Western Digital My Cloud Home, My Cloud Home Duo and SanDisk ibi which could allow an attacker to initiate installation of custom ZIP packages and overwrite system files. This could potentially lead to a code execution.

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 in Western Digital My Cloud Home, My Cloud Home Duo and SanDisk ibi devices allows attackers to manipulate ZIP package installation to overwrite system files using '..' sequences in file paths, potentially achieving arbitrary code execution.

MitigationApply vendor-supplied firmware updates when available; until then, restrict network access to the device's admin interface and monitor for unusual installation activity.

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 device model
    Access the device admin interface or check the product label to confirm the model is Western Digital My Cloud Home, My Cloud Home Duo, or SanDisk ibi
    Affected if Device is not one of these three models - not vulnerable
  2. Check firmware version
    Navigate to the device settings or system information page in the admin interface, or use the command 'cat /etc/version' or 'cat /mnt/boot/firmware_info' via SSH if enabled
    Affected if Firmware version is 8.12.0-178 or higher - not vulnerable; version is less than 8.12.0-178 or cannot be determined - potentially vulnerable
  3. Verify ZIP package installation feature access
    Check if the device admin interface exposes a plugin or app installation feature that accepts ZIP file uploads. Look for 'Add App', 'Install Package', or similar options in the web UI.
    Affected if The ZIP installation feature is present and accessible to authenticated users - vulnerable to exploitation
  4. Inspect for signs of exploitation
    Review system logs in /var/log/ for suspicious entries containing '../' sequences or unexpected file writes. Check if any system files were modified outside normal updates.
    Affected if Log entries show '..' sequences in file paths or unexpected modifications to system directories - likely exploitation has occurred

The device is affected if it is a My Cloud Home, My Cloud Home Duo, or SanDisk ibi model running firmware version lower than 8.12.0-178 and the ZIP package installation feature is accessible.
