"According to its banner, the version of Apache 2.2.x running on the
remote host is prior to 2.2.6. It is, therefore, affected by the
following vulnerabilities :

  - A denial of service vulnerability in mod_proxy. 
  - A cross-site scripting vulnerability in mod_status.
  - A local denial of service vulnerability associated with
    the Prefork MPM module.
  - An information leak in mod_cache.
  - A denial of service vulnerability in mod_cache.

In addition, it offers a workaround for a cross-site scripting issue
in mod_autoindex. 

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