remote host is prior to 2.0.63. It is, therefore, affected by multiple
cross-site  scripting vulnerabilities :

  - A cross-site scripting issue involving mod_imap.
    (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 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.");
