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
Improper Neutralization of Special Elements used in a Command ('Command Injection') vulnerability that could allow an attacker to execute code in the context of the root user on a vulnerable CGI file was discovered in Western Digital My Cloud OS 5 devicesThis issue affects My Cloud OS 5: before 5.26.119.

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 command injection vulnerability exists in Western Digital My Cloud OS 5 devices before version 5.26.119. The flaw is present in a CGI file and allows attackers to inject arbitrary commands that execute with root user privileges on the affected device.

MitigationUpdate My Cloud OS 5 firmware to version 5.26.119 or later. If immediate patching is not feasible, restrict network access to the device's administrative interface to limit exposure.

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. Check the installed My Cloud OS 5 firmware version
    Access the device administrative interface and navigate to Settings > About, or log in via SSH and run the command: cat /etc/version (or check the web UI for the firmware version display)
    Affected if The installed firmware version is 5.02.104 or higher but lower than 5.26.119
  2. Confirm the device model is My Cloud OS 5
    Log into the web administrative interface and check the device model name, or via SSH run: cat /proc/model or check the device label
    Affected if The device runs My Cloud OS 5 firmware and falls within the affected version range
  3. Determine if the CGI administrative interface is network-accessible
    Attempt to access the device login page from an external network location, or check router/firewall rules for port 80/443 forwarding to the device's local IP address
    Affected if The administrative web interface is reachable from untrusted networks, increasing exposure to the vulnerability

A user is affected if their Western Digital My Cloud OS 5 device runs firmware version 5.02.104 or higher but lower than 5.26.119 and has its administrative interface network-accessible.
