Flaws in Trane thermostats underscore IoT security risks, Cisco says
Cisco warned on Monday of serious flaws it found in an Internet-connected thermostat control, which it said are typical among products of vendors who aren’t well-versed in network security.
The flaws were found in the ComfortLink II thermostats made by Trane. The thermostats allow users to control room temperature from a mobile device, display the weather and even act as a digital photo frame.
Cisco’s Talos unit said the issues have now finally been patched since notifying Trane nearly two years ago, which is why it went public.
“The unfortunate truth is that securing internet-enabled devices is not always a high priority among vendors and manufacturers,” wrote Alex Chiu, a Cisco threat researcher, in a blog post Monday.
