[exp]

try this Url in your browser:

file:javascript:alert(123)



yeah. "file" protocol is a good thing for bypassing

URL-based security check.

one vulnerable function is

"window.external.NavigateAndFind" method.



you should have already known this:

top window and its iframe/frame share the same

"external" object.

so, BadSon method to conquer the "external" object.





[how]

how to get "file:javascript:" trick?

think about "mhtml:http:" for a while and i believed

there would be more.
