-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I am still unable to replicate. It launches FireFox (2.0.0.7) for me on my system and yeilds the error page "Firefox can't find the server at %xx..." If I replace the "%xx" with a null byte (inspired by the recent protocol handler problems in FF), then it still doesn't work, as per the mIRC string: http: $+ $chr(0) $+ ../../../../../../../../../../../windows/system32/calc.exe" So far, with various permutations of protocol handlers and odd characters, I can't reproduce this.

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. --Wednesday, October 3, 2007, 11:59:45 PM, you wrote to
