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 remote code execution vulnerability was discovered on Western Digital My Cloud devices where an attacker could trick a NAS device into loading through an unsecured HTTP call. This was a result insufficient verification of calls to the device. The vulnerability was addressed by disabling checks for internet connectivity using HTTP.

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 remote code execution vulnerability in Western Digital My Cloud NAS devices where insufficient verification of HTTP calls allows attackers to inject malicious code by intercepting or spoofing the device's internet connectivity checks performed over unsecured HTTP.

MitigationUpdate firmware to version that disables HTTP-based internet connectivity checks, or manually disable the HTTP connectivity check feature if present in device settings.

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 Western Digital My Cloud NAS
    Access the device web interface or check the product label/model number to verify the device is a Western Digital My Cloud series NAS
    Affected if Device is not a Western Digital My Cloud NAS - this CVE does not apply
  2. Check installed firmware version
    Log into the My Cloud dashboard, navigate to Settings > About or look for firmware version in the web UI footer. Alternatively, access the device via SSH and run: cat /etc/version or cat /mnt/boot/VERSION
    Affected if Firmware version is 5.19.117 or higher - the vulnerability was patched in this version
  3. Identify if HTTP connectivity check is enabled
    In the My Cloud web interface, go to Settings > Network > Internet or Settings > Network > Connectivity Check. Look for an option related to internet connectivity checks and verify whether it uses HTTP (instead of HTTPS) or is enabled at all
    Affected if HTTP-based internet connectivity checks are enabled - this is the vulnerable configuration that allows code injection via man-in-the-middle attacks

A user is affected if they have a Western Digital My Cloud NAS running firmware versions prior to 5.19.117 AND have the HTTP-based internet connectivity check feature enabled on their device.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to 5.19.117 or later
Fixed in 5.19.117
Interim mitigation

Update firmware to version that disables HTTP-based internet connectivity checks, or manually disable the HTTP connectivity check feature if present in device settings.

Recommended fix Moderate confidence

My Cloud OS 5.19.117 or later

  1. Upgrade the My Cloud OS firmware to version 5.19.117 or later via the device's web interface or management console
  2. After upgrading, verify the firmware version reflects 5.19.117 or higher in the device settings
  3. Confirm that the device no longer performs internet connectivity checks over HTTP
