[R2] Stand-alone Security Patch Available for Tenable.sc versions 5.16.0 to 5.19.1: Patch 202109.1

Read Time:23 Second
Tenable.sc leverages third-party software to help provide underlying functionality. One of the third-party components (OpenSSL) was found to contain vulnerabilities, and updated versions have been made available by the providers.

Out of caution, and in line with best practice, Tenable opted to upgrade the bundled OpenSSL components to address the potential impact of these issues. Tenable.sc patch SC-202109.1 updates OpenSSL to version 1.1.1l to address the identified vulnerabilities.

Project: 
Drupal core
Date: 
2021-September-15
Security risk: 
Moderately critical 12∕25 AC:Basic/A:None/CI:Some/II:None/E:Theoretical/TD:Default
Vulnerability: 
Access Bypass
CVE IDs: 
CVE-2020-13677
Description: 

Under some circumstances, the Drupal core JSON:API module does not properly restrict access to certain content, which may result in unintended access bypass.

Sites that do not have the JSON:API module enabled are not affected.

This advisory is not covered by Drupal Steward.

Solution: 

Install the latest version:

If you are using Drupal 9.2, update to Drupal 9.2.6.
If you are using Drupal 9.1, update to Drupal 9.1.13.
If you are using Drupal 8.9, update to Drupal 8.9.19.

Versions of Drupal 8 prior to 8.9.x and versions of Drupal 9 prior to 9.1.x are end-of-life and do not receive security coverage.

Drupal 7 core does not include the JSON:API module and therefore is not affected.

Vulnerability: 
Access bypass
CVE IDs: 
CVE-2020-13676
Description: 

The QuickEdit module does not properly check access to fields in some circumstances, which can lead to unintended disclosure of field data.

Sites are only affected if the QuickEdit module (which comes with the Standard profile) is installed.

This advisory is not covered by Drupal Steward.

Solution: 

Install the latest version:

If you are using Drupal 9.2, update to Drupal 9.2.6.
If you are using Drupal 9.1, update to Drupal 9.1.13.
If you are using Drupal 8.9, update to Drupal 8.9.19.

Versions of Drupal 8 prior to 8.9.x and versions of Drupal 9 prior to 9.1.x are end-of-life and do not receive security coverage.

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

Uninstalling the QuickEdit module will also mitigate the vulnerability. Site owners may wish to consider this option as the QuickEdit module will be removed from core in Drupal 10.

Drupal core – Moderately critical – Access bypass – SA-CORE-2021-008

Read Time:1 Minute, 22 Second
Project: 
Drupal core
Date: 
2021-September-15
Security risk: 
Moderately critical 11∕25 AC:Basic/A:None/CI:None/II:Some/E:Theoretical/TD:Uncommon
Vulnerability: 
Access bypass
CVE IDs: 
CVE-2020-13675
Description: 

Drupal’s JSON:API and REST/File modules allow file uploads through their HTTP APIs. The modules do not correctly run all file validation, which causes an access bypass vulnerability. An attacker might be able to upload files that bypass the file validation process implemented by modules on the site.

This vulnerability is mitigated by three factors:

The JSON:API or REST File upload modules must be enabled on the site.
An attacker must have access to a file upload via JSON:API or REST.
The site must employ a file validation module.

This advisory is not covered by Drupal Steward.

Also see GraphQL – Moderately critical – Access bypass – SA-CONTRIB-2021-029 which addresses a similar vulnerability for that module.

Solution: 

Install the latest version:

If you are using Drupal 9.2, update to Drupal 9.2.6.
If you are using Drupal 9.1, update to Drupal 9.1.13.
If you are using Drupal 8.9, update to Drupal 8.9.19.

Versions of Drupal 8 prior to 8.9.x and versions of Drupal 9 prior to 9.1.x are end-of-life and do not receive security coverage.

Drupal 7 core is not affected.

Drupal core – Moderately critical – Cross Site Request Forgery – SA-CORE-2021-007

Project: 
Drupal core
Date: 
2021-September-15
Security risk: 
Moderately critical 14∕25 AC:Complex/A:None/CI:Some/II:Some/E:Theoretical/TD:Default
Vulnerability: 
Cross Site Request Forgery
CVE IDs: 
CVE-2020-13674
Description: 

The QuickEdit module does not properly validate access to routes, which could allow cross-site request forgery under some circumstances and lead to possible data integrity issues.

Sites are only affected if the QuickEdit module (which comes with the Standard profile) is installed. Removing the “access in-place editing” permission from untrusted users will not fully mitigate the vulnerability.

This advisory is not covered by Drupal Steward.

Solution: 

Install the latest version:

If you are using Drupal 9.2, update to Drupal 9.2.6.
If you are using Drupal 9.1, update to Drupal 9.1.13.
If you are using Drupal 8.9, update to Drupal 8.9.19.

Versions of Drupal 8 prior to 8.9.x and versions of Drupal 9 prior to 9.1.x are end-of-life and do not receive security coverage.

Vulnerability: 
Cross Site Request Forgery
CVE IDs: 
CVE-2020-13673
Description: 

The Drupal core Media module allows embedding internal and external media in content fields.

Updated 18:15 UTC to clarify text.

Solution: 

Install the latest version:

If you are using Drupal 9.2, update to Drupal 9.2.6.
If you are using Drupal 9.1, update to Drupal 9.1.13.

WordPress 5.8.1 Security and Maintenance Release

Read Time:2 Minute, 31 Second

WordPress 5.8.1 is now available!

This security and maintenance release features 60 bug fixes in addition to 3 security fixes. Because this is a security release, it is recommended that you update your sites immediately. All versions since WordPress 5.4 have also been updated.

WordPress 5.8.1 is a short-cycle security and maintenance release. The next major release will be version 5.9.

You can download WordPress 5.8.1 by downloading from WordPress.org, or visit your Dashboard → Updates and click Update Now.

If you have sites that support automatic background updates, they’ve already started the update process.

Security Updates

3 security issues affect WordPress versions between 5.4 and 5.8. If you haven’t yet updated to 5.8, all WordPress versions since 5.4 have also been updated to fix the following security issues:

Props @mdawaffe, member of the WordPress Security Team for their work fixing a data exposure vulnerability within the REST API.Props to Michał Bentkowski of Securitum for reporting a XSS vulnerability in the block editor.The Lodash library has been updated to version 4.17.21 in each branch to incorporate upstream security fixes.

In addition to these issues, the security team would like to thank the following people for reporting vulnerabilities during the WordPress 5.8 beta testing period, allowing them to be fixed prior to release:

Props Evan Ricafort for reporting a XSS vulnerability in the block editor discovered during the 5.8 release’s beta period.Props Steve Henty for reporting a privilege escalation issue in the block editor.

Thank you to all of the reporters for privately disclosing the vulnerabilities. This gave the WordPress security team time to fix the vulnerabilities before WordPress sites could be attacked.

For more information, browse the full list of changes on Trac, or check out the version 5.8.1 HelpHub documentation page.

Thanks and props!

The 5.8.1 release was led by Jonathan Desrosiers and Evan Mullins.
