This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
Ecobee Ecobee4 4.2.0.171 devices can be forced to deauthenticate and connect to an unencrypted Wi-Fi network with the same SSID, even if the device settings specify use of encryption such as WPA2, as long as the competing network has a stronger signal. An attacker must be able to set up a nearby SSID, similar to an "Evil Twin" attack.
Remediation
Check the references section for vendor advisories and patches from ecobee. Update ecobee4_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
