Drupal 8.x < 8.4.5 Multiple Vulnerabilities (SA-CORE-2018-001)

Medium Nessus Plugin ID 107089


A PHP application running on the remote web server is affected by multiple vulnerabilities.


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.

- 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.


Upgrade to Drupal version 8.4.5 or later.
