CVE-2013-6951
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 maintain a set of Certification Authority public keys, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary X.509 certificate.
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 lacks SSL/TLS certificate validation by not maintaining a trusted Certificate Authority public key store. This allows man-in-the-middle attackers on the same network to present arbitrary X.509 certificates and impersonate SSL servers, intercepting or manipulating communications with the device.

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.
-
Locate WeMo device on your networkFind the IP address of your Belkin WeMo device by checking your router's connected devices list, using a network scanner app, or looking in the Belkin WeMo mobile app under device settings.Affected if You cannot locate the device - you need its IP address to proceed with version checking
-
Access the WeMo web interfaceOpen a web browser and navigate to http://[WeMo_IP_address]. Look for a Settings, About, or Device Information section that displays the firmware version.Affected if The web interface loads and shows a firmware version number
-
Compare your firmware version to the affected rangeNote the firmware version displayed. According to the CVE, versions before 3949 are affected, and version 2769 is explicitly listed as vulnerable.Affected if Firmware version is 2769 or any version below 3949 - the device lacks proper CA certificate validation for SSL/TLS connections
-
Confirm the SSL validation vulnerability existsThe vulnerability is inherent to the firmware code itself - the device does not maintain a trusted Certificate Authority public key store, meaning it cannot properly validate SSL server certificates.Affected if Running any firmware version below 3949 means the device will accept arbitrary X.509 certificates during SSL/TLS connections
You are affected if your WeMo device is running firmware version 2769 or any version prior to 3949, as these versions lack proper SSL/TLS certificate validation.

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 dataUpgrade WeMo firmware to version 3949 or later to implement proper CA certificate validation. Until patched, avoid using the device on untrusted networks and consider network segmentation.
