"The remote web server contains an application that is affected by
multiple vulnerabilities.");
  script_set_attribute(attribute:"description", value:
"According to its version number, the instance of MediaWiki running on
the remote host is affected by the following vulnerabilities :

  - Escape sequences are not properly sanitized when passed
    to the 'Sanitizer::checkCss' class, which allows a
    remote attacker to conduct cross-site scripting attacks.
    (CVE-2013-6451)

  - An input validation error exists in the
    'XmlTypeCheck.php' script in uploaded SVG files that
    contain external style sheets, which allows a remote
    attacker to conduct cross-site scripting attacks.
    (CVE-2013-6452)

  - Input validation by the checkSvgScriptCallback()
    function is bypassed in the 'UploadBase.php' script
    when an SVG file with invalid XML is uploaded. This
    can result in malicious code execution. (CVE-2013-6453)

  - An input validation error exists in the 'Sanitizer.php'
    script when input is submitted to the '-o-link'
    attribute, which allows cross-site scripting attacks in
    Opera 12. (CVE-2013-6454)

  - An information disclosure vulnerability exists in the
    log API, Enhanced Recent Changes feature, and users'
    watchlists that allows deleted log entries to be viewed.
    (CVE-2013-6472)

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

  - The TimedMediaHandler extension is affected by a
    cross-site scripting vulnerability due to the lack of
    input validation of the 'data-videopayload' attribute
    in the 'mw.PopUpThumbVideo.js' script. (CVE-2013-4574)

  - The Scribuntu extension is affected by a NULL pointer
    dereference and buffer overflow flaw in the
    implementation of the 'luasandbox' PHP extension that
    can lead to a denial of service or arbitrary code
    execution. (CVE-2013-4570, CVE-2013-4571)

  - The CentralAuth extension is affected by an information
    disclosure vulnerability due to the insertion of a
    username into the page's DOM. (CVE-2013-6455)

  - The Semantic Forms extension is affected by a cross-site
    request forgery (XSRF) vulnerability due to the lack of
    token validation in the 'Special:CreateCategory' page.
    (CVE-2014-3454)

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