#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. |
