CVE-2013-6950
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 does not use SSL for the distribution feed, which allows man-in-the-middle attackers to install arbitrary firmware by spoofing a distribution server.
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 versions prior to 3949 fetch firmware updates over an unencrypted HTTP connection (no SSL/TLS). A man-in-the-middle attacker positioned on the network can intercept these update requests, spoof the distribution server, and trick the device into downloading and installing malicious firmware, achieving complete device compromise.

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 firmware versionAccess the WeMo device's web interface (typically at the device's IP address) or use the WeMo mobile app to view the device firmware version information. Alternatively, send a UPN/SOAP request to the device's SOAP endpoint to query the firmware version.Affected if The installed firmware version is 2769 (or any version prior to 3949) and the device has not been updated to version 3949 or later.
-
Verify if firmware auto-update is enabledCheck the device settings through the WeMo web interface or mobile app for any auto-update or firmware update check settings. Look for configuration options related to 'Firmware Update' or 'Check for Updates'.Affected if The firmware update feature is enabled or configured to check for updates automatically, allowing the device to initiate update requests over the network.
-
Confirm the device network configurationInspect the network traffic or network configuration to determine if the device can communicate with external servers for firmware updates. Check if the device has outbound internet access.Affected if The device has network connectivity that allows it to make HTTP (non-SSL) requests to external servers for firmware distribution, enabling a man-in-the-middle attack vector.
The device is affected if it is running Belkin WeMo firmware version 2769 (or any version prior to 3949) and has the firmware update feature enabled with network access, allowing unencrypted HTTP firmware update requests to be intercepted.

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.
From vendor dataUpdate the Belkin WeMo firmware to version 3949 or later, which implements SSL/TLS encryption for the firmware distribution channel. If updating is not possible, ensure the device network is isolated from untrusted networks to reduce MITM attack exposure.
