CVE-2022-29841
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 an OS Command ('OS Command Injection') vulnerability that was caused by a command that read files from a privileged location and created a system command without sanitizing the read data. This command could be triggered by an attacker remotely to cause code execution and gain a reverse shell in Western Digital My Cloud OS 5 devices.This 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 confidenceOS command injection vulnerability in Western Digital My Cloud OS 5 devices. A command reads files from a privileged location and constructs a system command without sanitizing the read data, allowing remote attackers to execute arbitrary code and obtain a reverse shell.

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 My Cloud OS 5 firmware versionLog into the My Cloud device web UI and navigate to Settings > About, or run `cat /etc/version` via SSH to retrieve the installed firmware versionAffected if The installed version is greater than or equal to 5.02.104 AND less than 5.26.119
-
Verify the device is running My Cloud OS 5Confirm the device model and OS version by checking the web UI header or running `cat /etc/model` to ensure it is a My Cloud OS 5 device and not an older OS versionAffected if The device runs My Cloud OS 5 with version in the affected range
-
Check if remote access features are enabledInspect the device network settings via the web UI under Settings > Network > Remote Access, or check `/etc/smb.conf` for enabled shares and remote access configurationsAffected if Remote access, cloud access, or external-facing services are enabled on a vulnerable version
A user is affected if their My Cloud OS 5 device firmware version falls within the range 5.02.104 to 5.26.119 (inclusive of the lower bound, exclusive of the upper bound).
Generated from the published advisory. Verify against your own configuration.
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
