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

  - An input validation error exists related to handling
    previews of wikitext that allows cross-site scripting
    attacks. (CVE-2014-9276)

  - An input validation error exists related to flash policy
    mangling, API clients, and 'format=php' that allows
    cross-site scripting. (CVE-2014-9277)

  - An error exists related to 'content model' editing that
    allows a remote, unprivileged attacker to modify a
    user's 'common.js' file. (Bug 70901)

  - An error exists related to deleting an entry. The
    'DELETED_ACTION' and the action 'revdeleted' allows
    information disclosure via log files. (Bug 72222)

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