This is not a new vulnerability but was covered on Bugtraq in September by jelmer and Liu Die Yu. Jelmer highlighted the Media Bar Ressource Injection vulnerability in his exploit published on September 11, 2003 at http://securityfocus.com/archive/1/337285 Which followed Liu Die Yus post on September 10 about a Search Pane Injection vulnerability at http://www.securityfocus.com/archive/1/336931 However, both failed to elaborate that the _media and _search injections are possible through not only the FILE protocol but also the HTTP protocol. Your proof-of-concept is a good demonstration on how to extend these 2 related vulnerabilities to also cover arbitrary webpages such as Google or Passport.
