"According to its version number, the instance of MediaWiki running on
the remote host is affected by the following vulnerabilities :

  - Input validation errors exist that allow cross-site
    scripting attacks. (CVE-2013-4567, CVE-2013-4568)

  - An error exists related to session IDs and HTTP headers
    that allows an information disclosure. (CVE-2013-4572)

Additionally, the following extensions contain vulnerabilities but
are not enabled or installed by default (unless otherwise noted) : 

  - An input validation error exists related to the
    'CentralAuth' extension that allows cross-site request
    forgery (CSRF) attacks. (CVE-2012-5394)

  - An error exists in the 'CleanChanges' extension that
    allows an information disclosure related to
    'revision-deleted' IP addresses. (CVE-2013-4569)

  - An input validation error exists in the
    'ZeroRatedMobileAccess' extension that allows cross-site
    scripting attacks. (CVE-2013-4573)

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