"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
    API errors that allows reflected cross-site scripting
    attacks. (CVE-2014-9714, CVE-2015-2941)

  - An input validation error exists related to SVG file
    uploads that allows stored cross-site scripting attacks
    by bypassing a missing MIME type blacklist.
    (CVE-2015-2931)

  - An input validation error exists related to the handling
    of JavaScript used to animate elements in the
    'includes/upload/UploadBase.php' script that allows a
    remote attacker to bypass the blacklist filter.
    (CVE-2015-2932)

  - An input validation error exists in the
    'includes/Html.php' script that allows stored cross-site
    scripting attacks. (CVE-2015-2933)

  - A flaw in the 'includes/libs/XmlTypeCheck.php' script
    allows a remote attacker to bypass the SVG filter by
    encoding SVG entities. (CVE-2015-2934)

  - A flaw in the 'includes/upload/UploadBase.php' script
    allows a remote attacker to bypass the SVG filter and
    de-anonymize the wiki readers. This issue exists due to
    an incomplete fix for CVE-2014-7199. (CVE-2015-2935)

  - A denial of service vulnerability exists due to a flaw
    in the handling of hashing large PBKDF2 passwords.
    (CVE-2015-2936)

  - A denial of service vulnerability exists due to an XML
    external entity injection (XXE) flaw that is triggered
    by the parsing of crafted XML data. (CVE-2015-2937)

  - An input validation error exists related to the
    user-supplied custom JavaScript that allows stored
    cross-site scripting attacks. (CVE-2015-2938)

  - An input validation error exists related to the
    Scribunto extension that allows stored cross-site
    scripting attacks. (CVE-2015-2939)

  - A flaw in the CheckUser extension allows cross-site
    request forgery attacks due to a flaw in which user
    rights are not properly checked. (CVE-2015-2940)

  - A denial of service vulnerability exists due to an
    XML external entity (XXE) injection flaw triggered by
    the parsing of crafted XML data in SVG or XMP files.
    (CVE-2015-2942)

  - A cross-site scripting vulnerability exists due to
    improper validation of input encoded entities in SVG
    files. An unauthenticated, remote attacker can exploit
    this, via a specially crafted request, to execute
    arbitrary script code in a user's browser session.

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