Published: 2019-07-02

Description:
It was discovered as a part of the research on IoT devices in the most recent firmware for Blipcare device that the device allows to connect to web management interface on a non-SSL connection using plain text HTTP protocol. The user uses the web management interface of the device to provide the user's Wi-Fi credentials so that the device can connect to it and have Internet access.
