"According to its self-reported version, the instance of Drupal running
on the remote web server is 8.x prior to 8.4.5. It is, therefore,
affected by multiple vulnerabilities :

  - A flaw exists with the Comment Reply Form. An authenticated remote
    attacker could add or view comments that they do not have access
    to. (CVE-2017-6926)

  - A flaw exists with the Drupal.checkPlain() function due to
    improper handling of HTML injection. A remote attacker, with a
    specially crafted request, could potentially execute arbitrary
    script code within the trust relationship between the browser and
    server. (CVE-2017-6927)

  - A flaw exists with node access controls with a multilingual site
    due to defaulting to the untranslated version as a fallback. A
    remote attacker could potentially bypass access restrictions.
    (CVE-2017-6930)

  - A flaw exists with the Settings Tray module. A remote attacker
    could update data the do not have permission for. (CVE-2017-6931)

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