Me he encontrado esto x ahi fisgando en busca de un Exploit para XP que te de una shell remota, visto que el netcat me funciona como el culo xDD
... no se en que lenguaje está, ni siquiera si si es un fake o de verdad funciona, tampoco sabría como mandarlo desde windows, al parecer desde unix pone el commando al principio del archivo... si alguien puede testearlo y decir si funciona... afirma que te puede dar una shell del equipo al que se lanzaahi va...
/*
* 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
