HIGH Summary
In Drupal versions 8.4.x versions before 8.4.5 when using node access controls with a multilingual site, Drupal marks the untranslated version of a node as the default fallback for access queries. This fallback is used for languages that do not yet have a translated version of the created node. This can result in an access bypass vulnerability. This issue is mitigated by the fact that it only applies to sites that a) use the Content Translation module; and b) use a node access module such as Domain Access which implement hook_node_access_records().

NASL family CGI abuses NASL id DRUPAL_8_4_5.NASL description 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 last seen 2020-06-01 modified 2020-06-02 plugin id 107089 published 2018-03-01 reporter This script is Copyright (C) 2018-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/107089 title Drupal 8.x < 8.4.5 Multiple Vulnerabilities (SA-CORE-2018-001) NASL family Fedora Local Security Checks NASL id FEDORA_2018-906BA26B4D.NASL description - [8.4.6](https://www.drupal.org/project/drupal/releases/8 .4.6) - [SA-CORE-2018-002 (CVE-2018-7600)](https://www.drupal.org/SA-CORE-2018-002 ) - [8.4.5](https://www.drupal.org/project/drupal/releases/8 .4.5) - [SA-CORE-2018-001 (CVE-2017-6926 / CVE-2017-6927 / CVE-2017-6930 / CVE-2017-6931)](https://www.drupal.org/SA-CORE-2018-001) - [8.4.4](https://www.drupal.org/project/drupal/releases/8 .4.4) - [8.4.3](https://www.drupal.org/project/drupal/releases/8 .4.3) - [8.4.2](https://www.drupal.org/project/drupal/releases/8 .4.2) - [8.4.1](https://www.drupal.org/project/drupal/releases/8 .4.1) - [8.4.0](https://www.drupal.org/project/drupal/releases/8 .4.0) - [8.4.0-rc2](https://www.drupal.org/project/drupal/releas es/8.4.0-rc2) - [8.4.0-rc1](https://www.drupal.org/project/drupal/releas es/8.4.0-rc1) - [8.4.0-beta1](https://www.drupal.org/project/drupal/rele ases/8.4.0-beta1) - [8.4.0-alpha1](https://www.drupal.org/project/drupal/rel eases/8.4.0-alpha1) Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
