medium Web App Scanning Plugin ID 112947

Synopsis

Drupal 8.9.x < 8.9.18 Third-Party Library Vulnerability

Description

According to its self-reported version, the instance of Drupal running on the remote web server is 8.9.x prior to 8.9.18, 9.1.x prior to 9.1.12, or 9.2.x prior to 9.2.4. It is, therefore, affected by multiple vulnerabilities due to its usage of a third party component, CKEditor, for WYSIWYG editing:

- A vulnerability was discovered in CKEditor 4 Fake Objects package. The vulnerability allowed to inject malformed Fake Objects HTML, which could result in executing JavaScript code. (CVE-2021-37695)

- A vulnerability was discovered in the clipboard Widget plugin if used alongside the undo feature. The vulnerability allows a user to abuse undo functionality using malformed widget HTML, which could result in executing JavaScript code. (CVE-2021-32808)

- A vulnerability was discovered in CKEditor 4 Clipboard package. The vulnerability allowed to abuse paste functionality using malformed HTML, which could result in injecting arbitrary HTML into the editor. (CVE-2021-32809)

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

Solution

Update to Drupal version 8.9.18 or latest.
