Dear Gavin Hanover,
In this very case it's really seems to be mIRC problem ("unfiltered
shell characters"). It doesn't depend on URL handler and will work with
any valid URL handler. You can reproduce same vulnerability by entering
http:%xx../../../../../../../../../../../windows/system32/calc.exe".bat
Exploitable under Windows XP, not exploitable under Vista.
