CVE-2022-29842
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 · uneditedImproper 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 confidenceA 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.

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 checksWork through these to decide whether this CVE applies to you.
-
Check the installed My Cloud OS 5 firmware versionAccess 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
-
Confirm the device model is My Cloud OS 5Log into the web administrative interface and check the device model name, or via SSH run: cat /proc/model or check the device labelAffected if The device runs My Cloud OS 5 firmware and falls within the affected version range
-
Determine if the CGI administrative interface is network-accessibleAttempt 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 addressAffected 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.

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 · scoped5.26.119
Update 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.
My Cloud OS 5 version 5.26.119 or later
- Access the My Cloud OS 5 device administration web interface
- Navigate to the Settings or Settings > Firmware section
- Check for available firmware updates
- Update to firmware version 5.26.119 or later
- After the update completes, verify the firmware version has been upgraded to 5.26.119 or newer
