Detailsinfo

A vulnerability was found in Belkin WeMo 2769. It has been classified as problematic. This affects an unknown function of the component Distribution Feed. The manipulation with an unknown input leads to a cryptographic issue vulnerability. CWE is classifying the issue as CWE-310. This is going to have an impact on confidentiality. The summary by CVE is:

The 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.

The weakness was presented 02/18/2014 by Mike Davis with IOActive as VU#656302 as confirmed vulnerability note (CERT.org). The advisory is shared at kb.cert.org. The public release was coordinated in cooperation with Belkin. This vulnerability is uniquely identified as CVE-2013-6950 since 12/04/2013. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1600 for this issue.

The vulnerability was handled as a non-public zero-day exploit for at least 117 days. During that time the estimated underground price was around $0-$5k.

Upgrading to version Firmware 3949 eliminates this vulnerability.

The vulnerability is also documented in the databases at X-Force (91219) and SecurityFocus (BID 65631†). See VDB-12451, VDB-12452, VDB-12454 and VDB-12455 for similar entries. Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
