    NAFfileJPU

    [tested]
    Browser Ver
    {
    MS Internet Explorer: 6.0.2600.0000.xpclnt_qfe.021108-2107;
    Encryption: 128-bit;
    Patch:; Q810847;
    }
    (So, it's far from fully patched.)
    OS Ver: "Windows XP Cn ver"

    [demo]
    http://www.safecenter.net/liudieyu/NAFfileJPU/NAFfileJPU-MyPage.HTM
    or
    http://umbrella.mx.tc
    ---> NAFfileJPU section
    ---> NAFfileJPU-MyPage file

    [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.

    [greetings]
    the Pull, dror, guninski, sandblad and "Friedrich L.Bauer".
    of course, mom and dad.

    best wishes
