Description

This exploit leverages a file write vulnerability in the print spooler service
which will restart if stopped. Because the service cannot be stopped long
enough to remove the dll, there is no way to remove the dll once
it is loaded by the service. Essentially, on default settings, this module
adds a permanent elevated backdoor.
