CVE-2022-29837
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 · uneditedA path traversal vulnerability was addressed in Western Digital My Cloud Home, My Cloud Home Duo and SanDisk ibi which could allow an attacker to initiate installation of custom ZIP packages and overwrite system files. This could potentially lead to a code execution.
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 path traversal vulnerability in Western Digital My Cloud Home, My Cloud Home Duo and SanDisk ibi devices allows attackers to manipulate ZIP package installation to overwrite system files using '..' sequences in file paths, potentially achieving arbitrary code execution.

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.
-
Identify device modelAccess the device admin interface or check the product label to confirm the model is Western Digital My Cloud Home, My Cloud Home Duo, or SanDisk ibiAffected if Device is not one of these three models - not vulnerable
-
Check firmware versionNavigate to the device settings or system information page in the admin interface, or use the command 'cat /etc/version' or 'cat /mnt/boot/firmware_info' via SSH if enabledAffected if Firmware version is 8.12.0-178 or higher - not vulnerable; version is less than 8.12.0-178 or cannot be determined - potentially vulnerable
-
Verify ZIP package installation feature accessCheck if the device admin interface exposes a plugin or app installation feature that accepts ZIP file uploads. Look for 'Add App', 'Install Package', or similar options in the web UI.Affected if The ZIP installation feature is present and accessible to authenticated users - vulnerable to exploitation
-
Inspect for signs of exploitationReview system logs in /var/log/ for suspicious entries containing '../' sequences or unexpected file writes. Check if any system files were modified outside normal updates.Affected if Log entries show '..' sequences in file paths or unexpected modifications to system directories - likely exploitation has occurred
The device is affected if it is a My Cloud Home, My Cloud Home Duo, or SanDisk ibi model running firmware version lower than 8.12.0-178 and the ZIP package installation feature is 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 · scoped8.12.0-178
Apply vendor-supplied firmware updates when available; until then, restrict network access to the device's admin interface and monitor for unusual installation activity.
My Cloud Home/My Cloud Home Duo/SanDisk ibi Firmware: 8.12.0-178 or later
- 1. Identify the affected device model (My Cloud Home, My Cloud Home Duo, or SanDisk ibi)
- 2. Access the device web interface or Western Digital support portal
- 3. Download the firmware version 8.12.0-178 or later from the official Western Digital support website
- 4. Follow the manufacturer's firmware upgrade instructions to apply the update
- 5. Verify the firmware version after upgrade to confirm the patch was applied
