Playa Vista, Calif., February 18, 2014 – Belkin has corrected the list of five potential vulnerabilities affecting the WeMo line of home automation solutions that was published in a CERT advisory on February 18. Belkin was in contact with the security researchers prior to the publication of the advisory, and, as of February 18, had already issued fixes for each of the noted potential vulnerabilities via in-app notifications and updates. Users with the most recent firmware release (version 3949) are not at risk for malicious firmware attacks or remote control or monitoring of WeMo devices from unauthorized devices as described in the report. Belkin urges such users to download the latest app from the App Store (version 1.4.2) or Google Play Store (version 1.1.2) and then upgrade the firmware version through the app.
Specific fixes Belkin has issued include:
- An update to the WeMo API server on November 5, 2013 that prevents an XML injection attack from gaining access to other WeMo devices.
- An update to the WeMo firmware, published on January 24, 2014, that adds SSL encryption and validation to the WeMo firmware distribution feed, eliminates storage of the signing key on the device, and password protects the serial port interface to prevent a malicious firmware attack
- An update to the WeMo app for both iOS (published on January 24, 2014) and Android (published on February 10, 2014) that contains the most recent firmware update
