[R1] Tenable.sc 5.20.0 Fixes Multiple Vulnerabilities

Read Time:28 Second
Tenable.sc versions 5.14.0 through 5.19.1 were found to contain a remote code execution vulnerability which could allow a remote, unauthenticated attacker to execute code under special circumstances. An attacker would first have to stage a specific file type in the web server root of the Tenable.sc host prior to remote exploitation.

Also, Tenable.sc leverages third-party software to help provide underlying functionality. One of the third-party components (Apache) was found to contain vulnerabilities, and updated versions have been made available by the providers.

Drupal core – Moderately critical – Cross Site Scripting – SA-CORE-2021-011

Read Time:1 Minute, 30 Second
Project: 
Drupal core
Date: 
2021-November-17
Security risk: 
Moderately critical 13∕25 AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:Default
Vulnerability: 
Cross Site Scripting
Description: 

The Drupal project uses the CKEditor library for WYSIWYG editing. CKEditor has released a security update that impacts Drupal, along with a hotfix for that update.

Vulnerabilities are possible if Drupal is configured to allow use of the CKEditor library for WYSIWYG editing. An attacker that can create or edit content (even without access to CKEditor themselves) may be able to exploit one or more Cross-Site Scripting (XSS) vulnerabilities to target users with access to the WYSIWYG CKEditor, including site admins with privileged access.

For more information, see CKEditor’s security advisories:

CVE-2021-41165: HTML comments vulnerability allowing to execute JavaScript code
CVE-2021-41164: Advanced Content Filter (ACF) vulnerability allowing to execute JavaScript code using malformed HTML

This advisory is not covered by Drupal Steward.

Solution: 

Install the latest version:

If you are using Drupal 9.2, update to Drupal 9.2.9.
If you are using Drupal 9.1, update to Drupal 9.1.14.
If you are using Drupal 8.9, update to Drupal 8.9.20.

Versions of Drupal prior to 9.1.x are end-of-life and do not receive security coverage.

Note that Drupal 8 has reached its end of life so this is the final security release provided for Drupal 8.

Drupal 7 core does not include the CKEditor module and therefore is not affected.

Jacek Bogdański coordinated on the release with Drupal project.
