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

  - A flaw exists because the application fails to validate
    input passed via uploaded SVG files before returning it
    to the user. This allows a remote attacker to conduct
    cross-site scripting (XSS) attacks. (CVE-2013-2031)

  - A flaw exists that allows an attacker to bypass the
    password change blocking mechanism. (CVE-2013-2032)

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