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
Addressed a remote code execution vulnerability by resolving a command injection vulnerability and closing an AWS S3 bucket that potentially allowed an attacker to execute unsigned code on My Cloud Home devices.

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

This vulnerability involved command injection in My Cloud Home devices combined with an improperly secured AWS S3 bucket that allowed attackers to upload and execute unsigned code. The CVSS 9.8 score reflects the critical severity of remote code execution on affected devices.

MitigationEnsure My Cloud Home devices are updated to the patched firmware version that closes the command injection vector and secures the S3 bucket. Verify no unauthorized code execution paths exist and review S3 bucket policies for proper access controls.

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 your My Cloud Home device model
    Locate the device model label on the physical device or in the device management interface - confirm whether it is a My Cloud Home or My Cloud Home Duo
    Affected if The device is a Western Digital My Cloud Home or My Cloud Home Duo
  2. Check the installed firmware version
    Access the device dashboard or administrative interface and navigate to the firmware or system information section to view the current firmware version number
    Affected if The firmware version is lower than 8.5.1-102 (for example, 8.5.0 or earlier)
  3. Verify command injection exposure
    Review device logs and network traffic for any evidence of unexpected or unauthorized command execution, or unusual network connections originating from the device
    Affected if Unexpected commands or scripts are found in logs, or the device exhibits unexplained network behavior
  4. Inspect for unauthorized code execution
    Check the device file system or any associated storage for unexpected executable files, scripts, or binaries that were not installed through official channels
    Affected if Unsigned or unauthorized code files are present on the device or attached storage
  5. Review S3 bucket access controls
    If the device is configured with cloud storage integration, audit the associated AWS S3 bucket policies and access permissions for overly permissive settings
    Affected if The S3 bucket allows public write access or lacks proper authentication controls

The environment is affected if the device is a Western Digital My Cloud Home or My Cloud Home Duo running firmware version lower than 8.5.1-102, or if unauthorized code execution paths or improperly secured S3 bucket configurations are detected.

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 8.5.1-102 or later
Fixed in 8.5.1-102
Interim mitigation

Ensure My Cloud Home devices are updated to the patched firmware version that closes the command injection vector and secures the S3 bucket. Verify no unauthorized code execution paths exist and review S3 bucket policies for proper access controls.

Recommended fix High confidence

Firmware 8.5.1-102 or later

  1. 1. Identify the current firmware version of the My Cloud Home or My Cloud Home Duo device through the device interface or admin panel
  2. 2. Navigate to the official Western Digital support website and locate the firmware download section for My Cloud Home devices
  3. 3. Download firmware version 8.5.1-102 or later for your specific device model
  4. 4. Follow the official firmware update instructions provided by Western Digital to apply the update
  5. 5. After the update completes, verify that the installed firmware version shows 8.5.1-102 or higher
Caveat Firmware updates carry inherent risk; ensure power continuity during update and backup critical data before proceeding
