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. |
