"According to its banner, the version of Apache 2.2.x running on the
remote host is prior to 2.2.8. It is, therefore, affected by the
following vulnerabilities :

  - A cross-site scripting issue involving mod_imagemap
    (CVE-2007-5000).

  - A cross-site scripting issue involving 413 error pages
    via a malformed HTTP method (PR 44014 / CVE-2007-6203).

  - A cross-site scripting issue in mod_status involving 
    the refresh parameter (CVE-2007-6388).

  - A cross-site scripting issue in mod_proxy_balancer
    involving the worker route and worker redirect 
    string of the balancer manager (CVE-2007-6421).

  - A denial of service issue in the balancer_handler
    function in mod_proxy_balancer can be triggered by
    an authenticated user when a threaded Multi-
    Processing Module is used (CVE-2007-6422).

  - A cross-site scripting issue using UTF-7 encoding
    in mod_proxy_ftp exists because it does not 
    define a charset (CVE-2008-0005).

Note that the remote web server may not actually be affected by these
vulnerabilities. Nessus did not try to determine whether the affected
modules are in use or to check for the issues themselves.");
