CVE-2022-23006
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 stack-based buffer overflow vulnerability was found on Western Digital My Cloud Home, My Cloud Home Duo, and SanDisk ibi that could allow an attacker accessing the system locally to read information from /etc/version file. This vulnerability can only be exploited by chaining it with another issue. If an attacker is able to carry out a remote code execution attack, they can gain access to the vulnerable file, due to the presence of insecure functions in code. User interaction is required for exploitation. Exploiting the vulnerability could result in exposure of information, ability to modify files, memory access errors, or system crashes.
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 stack-based buffer overflow vulnerability exists in Western Digital My Cloud Home, My Cloud Home Duo, and SanDisk ibi devices. The vulnerability stems from insecure functions in the firmware code that allow reading the /etc/version file when chained with another vulnerability (such as remote code execution). Exploitation requires local access to the system and user interaction.

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 the device modelAccess the device admin interface or check the physical device label to confirm the exact model (My Cloud Home, My Cloud Home Duo, or SanDisk ibi)Affected if The device is not one of these three models, then it is not affected by this CVE
-
Determine the installed firmware versionAccess the device settings page in the web interface and locate the firmware version information, or connect to the device via SSH/Telnet and run: cat /etc/versionAffected if The firmware version is lower than 8.10.0-117 (for example, 8.9.x or earlier), indicating the device is running a vulnerable version
-
Verify the vulnerable binary existsIf SSH/Telnet access is available, check for the existence of the binary that performs the insecure file read: ls -la /sbin/<binary_name> or examine the firmware filesystem for binaries that read /etc/version using insecure functions like strcpy or sprintfAffected if The binary containing the insecure function exists on the device firmware, confirming the vulnerable code path is present
-
Check for indicators of chained vulnerabilityReview system logs for signs of remote code execution or other exploitation attempts, and check for unauthorized processes or network connections that could indicate a preliminary compromise needed to chain with this vulnerabilityAffected if Evidence exists of a separate vulnerability (such as RCE) having been exploited, which could then be chained with this vulnerability to read /etc/version
The device is affected if it is a My Cloud Home, My Cloud Home Duo, or SanDisk ibi device running firmware version below 8.10.0-117 and the vulnerable code reading /etc/version is present.

dbcve · scoped8.10.0-117
This is a firmware-level vulnerability requiring a vendor patch from Western Digital. Users should restrict local system access to trusted personnel only and await an official firmware update that addresses the insecure functions in the code.
Firmware version 8.10.0-117 or later
- 1. Identify the current firmware version of the WD My Cloud Home, My Cloud Home Duo, or SanDisk ibi device
- 2. Download firmware version 8.10.0-117 or later from the official Western Digital support site (support.westerndigital.com)
- 3. Access the device web interface and navigate to Settings > Firmware Update
- 4. Upload and apply the downloaded firmware update file
- 5. Wait for the update process to complete and the device to restart
- 6. Verify the firmware has been updated successfully by checking the version in Settings > About
