Meross MSH30Q 4.5.23 is vulnerable to Cleartext Transmission of Sensitive Information. During the device setup phase, the MSH30Q creates an unprotected Wi-Fi access point. In this phase, MSH30Q needs to connect to the Internet through a Wi-Fi router. This is why MSH30Q asks for the Wi-Fi network name (SSID) and the Wi-Fi network password. When the user enters the password, the transmission of the Wi-Fi password and name between the MSH30Q and mobile application is observed in the Wi-Fi network. Although the Wi-Fi password is encrypted, a part of the decryption algorithm is public so we complemented the missing parts to decrypt it.

Meross Smart Wi-Fi 2 Way Wall Switch (MSS550X), on its 3.1.3 version and before, creates an open Wi-Fi Access Point without the required security measures in its initial setup. This could allow a remote attacker to obtain the Wi-Fi SSID as well as the password configured by the user from Meross app via Http/JSON plain request.
