Internet Explorer 6 and perhaps 7 should be triggered by this.
Please see: http://ha.ckers.org/xss.html for more information.
Browser Tested: Internet Explorer 7 (FireFox 3 was tested for the other vulnerabilities)
-:: Solution ::-
Secure redirection calls with referer headers (just an example) and filter bad characters.
Conclusion:
This system was fun to find bad code in, it sure had a nice diversity of vulnerabilities.
