    A vulnerability has been reported in Mozilla and Mozilla Firefox, allowing malicious websites to spoof the user interface.

    The problem is that Mozilla and Mozilla Firefox don't restrict websites from including arbitrary, remote XUL (XML User Interface Language) files. This can be exploited to "hijack" most of the user interface (including tool bars, SSL certificate dialogs, address bar and more), thereby controlling almost anything the user sees.

    The Mozilla user interface is built using XUL files.

    A PoC (Proof of Concept) exploit for Mozilla Firefox has been published. The PoC spoofs a SSL secured PayPal website.

    This has been confirmed using Mozilla 1.7 for Linux, Mozilla Firefox 0.9.1 for Linux, Mozilla 1.7.1 for Windows and Mozilla Firefox 0.9.2 for Windows. Prior versions may also be affected.

    NOTE: This issue appears to be the same as Mozilla Bug 244965.

    Do not follow links from untrusted sites.

    Reported in Mozilla Firefox by:
    Jérôme ATHIAS (also created a PoC)

    Reported in Mozilla by:
    James Ross

    2004-07-30: Added an additional Mozilla Bug reference.

    Ah a fellow Singaporean.

    http://forums.mozillazine.org/viewtopic.php?t=102334 is another good discussion on this fairly old issue. Some solutions are presented. You would have to do some "Scary" configuration changes. To wit

    user_pref("dom.disable_window_open_feature.close", true);
    user_pref("dom.disable_window_open_feature.directories", true);
    user_pref("dom.disable_window_open_feature.location", true);
    user_pref("dom.disable_window_open_feature.menubar", true);
    user_pref("dom.disable_window_open_feature.minimizable", true);
    user_pref("dom.disable_window_open_feature.personalbar", true);
    user_pref("dom.disable_window_open_feature.resizable", true);
    user_pref("dom.disable_window_open_feature.scrollbars", true);

    I know you are 13 years old. (or at least between 13 to 16 from your postings).

    It's rare to see someone from Asia much less Singapore. The last time there was such a poll, I recall only 2 people from Asia.

    I'm already registered.

    As for being a "pro", I'm no more a pro than you, I suspect.
