CODE

/*
* WinME/XP UPNP dos & overflow
*
* Run: ./XPloit host <option>
*
* Windows run the "Universal Plug and Play technology" service
* at port 5000. In the future this will allow for seemless
* 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

Hehe...about every 2 months or so on this board someone makes a post about the amazing "new" UPNP vulnerability. Everyone gets excited, starts compiling it, then realizes that its old and doesn't work...then the cycle repeats itself.

If u don't believe me search for UPNP in the forum and u'll see what i mean.

this one isnt to old it got "updated" except the fact that it doesnt work worth shit ;D well the dos supposidly works, meh. some guy in the download section said he got 154 machines locally... i havent tried locally, but ive tried remote and its been a fail.
