Belkin Confirm ‘Vulnerabilities’ Affecting WeMo

Belkin Confirm

The move follows a report this week by security experts OActive that a password leak allows others to remotely control WeMo devices, perform malicious firmware updates, and access an internal home network.
The company has now corrected the list of five potential vulnerabilities affecting the WeMo line of home automation solutions, published in a CERT advisory on February 18. 

Belkin said it was in contact with the security researchers prior to the publication of the advisory, and, issued fixes for each of the 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. 

Belkin urges such users to download the latest app from the App Store (version 1.4.1) or Google Play Store (version 1.2.1) and then upgrade the firmware version through the app.

Specific fixes Belkin has issued include:

1)      An update to the WeMo API server on November 5, 2013 that prevents an XML injection attack from gaining access to other WeMo devices.

2)      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

3)      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
