The remote host is using Mozilla and/or Firefox, an alternative web browser. This web browser supports the XUL (XML User Interface Language), a language designed to manipulate the user interface of the browser itself. Since XUL gives the full control of the browser GUI to the visited websites, an attacker may use it to spoof a third party website and therefore pretend that the URL and Certificates of the website are legitimate. In addition to this, the remote version of this browser is vulnerable to a flaw which may allow a malicious web site to spoof security properties such as SSL certificates and URIs.
