The time-based one-time-password (TOTP) function in the application logic of the Green Electronics RainMachine Mini-8 (2nd generation) uses the administrator's password hash to generate a 6-digit temporary passcode that can be used for remote and local access, aka a "Use of Password Hash Instead of Password for Authentication" issue. This is exploitable by an attacker who discovers a hash value in the rainmachine-settings.sqlite file.

The 'Weather Service' feature of the Green Electronics RainMachine Mini-8 (2nd generation) allows an attacker to inject arbitrary Python code via the 'Add new weather data source' upload function.

A persistent Cross Site Scripting (XSS) vulnerability in the Green Electronics RainMachine Mini-8 (2nd Generation) and Touch HD 12 web application allows an attacker to inject arbitrary JavaScript via the REST API.

A Cross Site Request Forgery (CSRF) vulnerability in the Green Electronics RainMachine Mini-8 (2nd Generation) and Touch HD 12 web application allows an attacker to control the RainMachine device via the REST API.

An authentication bypass vulnerability exists in the Green Electronics RainMachine Mini-8 (2nd Generation) and Touch HD 12 web application allowing an unauthenticated attacker to perform authenticated actions on the device via a 127.0.0.1:port value in the HTTP 'Host' header, as demonstrated by retrieving credentials.

A missing X-Frame-Options header in the Green Electronics RainMachine Mini-8 (2nd Generation) and Touch HD 12 web application could be used by a remote attacker for clickjacking, as demonstrated by triggering an API page request.
