Multiple Vulnerabilities in Mozilla Products Could Allow for Arbitrary Code Execution

Read Time:44 Second

Multiple vulnerabilities have been discovered in Mozilla Firefox and Mozilla Thunderbird, the most severe of which could allow for arbitrary code execution.

Mozilla Firefox is a web browser used to access the Internet.
Mozilla Firefox ESR is a version of the web browser intended to be deployed in large organizations.
Mozilla Thunderbird is a free and open-source cross-platform email client, personal information manager, news client, RSS and chat client
Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution in the context of the logged on user. Depending on the privileges associated with the user an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

Drupal core – Critical – Multiple vulnerabilities – SA-CORE-2022-016

Read Time:1 Minute, 36 Second
Project: 
Drupal core
Date: 
2022-September-28
Security risk: 
Critical 18∕25 AC:Basic/A:Admin/CI:All/II:All/E:Proof/TD:All
Vulnerability: 
Multiple vulnerabilities
Affected versions: 
>= 8.0.0 <9.3.22 || >= 9.4.0 <9.4.7
CVE IDs: 
CVE-2022-39261
Description: 

Drupal uses the Twig third-party library for content templating and sanitization. Twig has released a security update that affects Drupal. Twig has rated the vulnerability as high severity.

Drupal core’s code extending Twig has also been updated to mitigate a related vulnerability.

Multiple vulnerabilities are possible if an untrusted user has access to write Twig code, including potential unauthorized read access to private files, the contents of other files on the server, or database credentials.

The vulnerability is mitigated by the fact that an exploit is only possible in Drupal core with a restricted access administrative permission. Additional exploit paths for the same vulnerability may exist with contributed or custom code that allows users to write Twig templates.

Solution: 

Install the latest version:

If you are using Drupal 9.4, update to Drupal 9.4.7.

If you are using Drupal 9.3, update to Drupal 9.3.22.

All versions of Drupal 9 prior to 9.3.x are end-of-life and do not receive security coverage. Note that Drupal 8 has reached its end of life.

Drupal 7 core does not include Twig and therefore is not affected.
