Hello Ryan,

Yes,  this  one is to another hole reported on Bugtraq by milo omega and
covered by MS01-54

http://www.security.nnov.ru/search/news.asp?binid=1518

There are another exploits known in-the-wild to this problem.

Is this an exploit to the most recent UPnP hole that was posted to

RP> bugtraq?

In the discussion of that vulnerability it was stated that UPnP was on UDP
port 1900.

Am I just confused?

This code is NOT by me... I found it on the net today and thought that

RP> you

guys may enjoy it. I saw no copyrights on this or messages stating NOT

RP> to

post this code.

/*
 * WinME/XP UPNP dos & overflow

 * Run: ./XPloit host <option>
 *
 * Windows run the "Universal Plug and Play technology" service

 * connectivity of various devices such as a printer.
 * This service have a DoS and a buffer overflow I exploit here.

 * PD: the -e option spawns a cmd.exe shell on port 7788 coded by isno
