# 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.
