    http TRACE XSS attack

    AlienVault has identified a vulnerbility with our Zabbix installation. I'm not sure how to resolve this. May also be a false positive. Could use some help figuring it out. I can't find apache config files on our CentOS (cmd line) installation of zabbix.

    Port:80
    Scanner ID:11213
    Risk:6
    Description:Vulnerability Detection Result:

    Solution:
    Add the following lines for each virtual host in your configuration file :

    RewriteEngine on
    RewriteCond %{REQUEST_METHOD} ^(TRACE|TRACK)
    RewriteRule .* - [F]

    See also http://httpd.apache.org/docs/current...ml#traceenable

    Summary:

    Debugging functions are enabled on the remote HTTP server.

    The remote webserver supports the TRACE and/or TRACK methods. TRACE and TRACK
    are HTTP methods which are used to debug web server connections.

    It has been shown that servers supporting this method are subject to
    cross-site-scripting attacks, dubbed XST for Cross-Site-Tracing, when
    used in conjunction with various weaknesses in browsers.

    An attacker may use this flaw to trick your legitimate web users to give
    him their credentials.

    Solution:

    Disable these methods.
