Unconstrained Web access to the devices private encryption key in the QR code pairing mode in the eWeLink mobile application (through 4.9.2 on Android and through 4.9.1 on iOS) allows a physically proximate attacker to eavesdrop on Wi-Fi credentials and other sensitive information by monitoring the Wi-Fi spectrum during a device pairing process.
The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
