CVE-2013-6952
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 · uneditedThe Belkin WeMo Home Automation firmware before 3949 has a hardcoded GPG key, which makes it easier for remote attackers to spoof firmware updates and execute arbitrary code via crafted signed data.
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 confidenceThe Belkin WeMo Home Automation firmware before version 3949 contains a hardcoded GPG signing key embedded in the firmware image. This allows remote attackers who obtain the key to craft malicious firmware updates that appear legitimate to the device, enabling arbitrary code execution via the firmware update mechanism.

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 WeMo firmware versionAccess the WeMo device's web interface (typically at the device's IP address) and navigate to the Device Settings or Firmware Information section. Alternatively, use the WeMo mobile app to view device information, which displays the current firmware version.Affected if Firmware version is 2769 or any version earlier than 3949 (the version number displayed is lower than 3949)
You are affected if your Belkin WeMo device runs firmware version 2769 or any version prior to 3949, as these contain the hardcoded GPG signing key that could allow malicious firmware updates to be accepted by your device.
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 · scopedUpdate WeMo firmware to version 3949 or later, which should remove the hardcoded key. For ongoing protection, implement secure key management with per-device unique keys and ensure firmware update validation properly verifies the signing key is not compromised.
Firmware version 3949 or later
- Identify the current firmware version of the Belkin WeMo device
- Navigate to the Belkin WeMo support page or use the WeMo app to check for firmware updates
- Upgrade the firmware to version 3949 or later (the fixed release)
- Verify the upgrade was successful by checking the firmware version after updating
- Ensure the device is connected to a trusted network after the update
