Hej avatar2005,

Here you see what they (developers) do on it, but the flaw lies with M$ basically to reappear:

You can manipulate through ole automization,through IGMP 224.0.0.2, UDP in dhcp (68) etc.
exploiting inside the windows system 32 file: notepad.exe ; explorer.exe, hijackthis.exe through browseui.dll. The exploit is a couple of years old and a favorite for malcreants to exploit firefox via IE explorer, and watch for traffic on port 2709! It is a sneaky exploit you have to watch out for.
ProtoWall as an addition to harden your FW can be advisable.
