Use of hard-coded cryptographic key vulnerability in August Connect Wi-Fi Bridge App, Connect Firmware allows an attacker to decrypt an intercepted payload containing the Wi-Fi network authentication credentials. This issue affects: August Connect Wi-Fi Bridge App version v10.11.0 and prior versions on Android. August Connect Firmware version 2.2.12 and prior versions.

An issue was discovered on August Connect devices. Insecure data transfer between the August app and August Connect during configuration allows attackers to discover home Wi-Fi credentials. This data transfer uses an unencrypted access point for these credentials, and passes them in an HTTP POST, using the AugustWifiDevice class, with data encrypted with a fixed key found obfuscated in the app.
