Firefox < 1.0 Multiple Spoofing Vulnerabilities

Critical Nessus Plugin ID 14181


The remote Windows host has a web browser installed that is affected by multiple vulnerabilities.


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 website to spoof security properties such as SSL certificates and URIs.


There is no known solution at this time.
