remote web server is affected by multiple vulnerabilities :

  - The application is affected by a server-side request
    forgery vulnerability in the 'pingback.ping' method
    used in 'xmlrpc.php'. This vulnerability can be used to
    expose information and remotely port scan a host using
    pingbacks. (CVE-2013-0235)

  - The application is affected by two instances of
    cross-site scripting (XSS) attacks via shortcodes and
    post content. (CVE-2013-0236)

  - The application is affected by a cross-site scripting
    (XSS) vulnerability in the Plupload external library.
    (CVE-2013-0237)

Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported version number.");
