This module exploits MQTT creds dump vulnerability in Servisnet Tessa. The app.js is publicly available which acts as the backend of the application. By exposing a default value for the "Authorization" HTTP header, it is possible to make unauthenticated requests to some areas of the application. Even MQTT(Message Queuing Telemetry Transport) protocol connection information can be obtained with this method. A new admin user can be added to the database with this header obtained in the source code. The module tries to log in to the MQTT service with the credentials it has obtained, and reflects the response it receives from the service.
