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
Insufficiently Protected Credentials vulnerability in the remote backups application on Western Digital My Cloud devices that could allow an attacker who has gained access to a relevant endpoint to use that information to access protected data. This issue affects: Western Digital My Cloud My Cloud versions prior to 5.25.124 on Linux.

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

Insufficiently protected credentials in the remote backups application on Western Digital My Cloud NAS devices allows an attacker with endpoint access to retrieve credentials and access protected data. The vulnerability stems from credentials being exposed or inadequately secured in the remote backup functionality.

MitigationUpgrade Western Digital My Cloud firmware to version 5.25.124 or later, which contains the fix for proper credential protection in the remote backups application.

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 device is a Western Digital My Cloud NAS
    Identify the device model through the web interface (usually at mycloud.com or direct IP access) or physical labeling. This vulnerability affects only Western Digital My Cloud devices.
    Affected if The device is a Western Digital My Cloud NAS model
  2. Check the installed firmware version
    Access the My Cloud dashboard, navigate to Settings > About to view the firmware version. Compare this version number against 5.25.124.
    Affected if The firmware version is lower than 5.25.124
  3. Verify if remote backup functionality is configured
    In the My Cloud dashboard, navigate to Backup > Remote Backup or Settings > Remote Backup to check if any remote backup jobs are configured or enabled.
    Affected if Remote backup jobs are configured or the remote backup feature is in use
  4. Inspect for exposed credential storage
    Check the device configuration files or backup job settings for any plaintext or inadequately protected credentials associated with remote backup destinations.
    Affected if Credentials for remote backup destinations are stored in an unsecured or plaintext format

The device is affected if it is a Western Digital My Cloud NAS running firmware below version 5.25.124 with the remote backup feature configured.
