Security patches for APSB22-48

This repository contains Magento 2 Patch Files for the recently found security issues on 12-10-2022. The patch files aim to fix the CVE-2022-35698 and CVE-2022-35689 vulnerabilities.

There is not much information about the exact fix which has been released in the newly released patch versions of Magento. To create these patch files we've tried our best to inspect the 2.4.4-p1...2.4.4-p2 diff and extract the possible security fixes which seems to be in the Magento template directives.

Contents

As of now the patch only applies a few fixes in the Magento/Framework/Filter namespace which have been extracted from the following commit: Patch Commit

According to the newly released Magento patches this covers the current security issue.

The magento/module-customer patch applies a fix to the Webapi for Customer creation and Customer Confirmation Controller.

• The Webapi patch fixes an issue where it used to be possible to send multiple keys with different capitalized key fields thus possibly ignoring any validation made by Magento.
• The Confirmation Controller is changed to cast a id POST parameter to an integer.

The magento/framework patch applies a fix to the CMS template directive parsing, a signature is added and a depth check. We think the cause could be issues with nested CMS directives in Magento 2 and certain customer data being exposed to a XSS attack.

Installation

Use a package such as cweagans/composer-patches or vaimo/composer-patches to apply the correct patch file to your Magento shop. The patches are to be applied to the magento/framework and magento/module-customer package. The correct patch file can be found within the folder corresponding to your Magento 2 version.

Make sure to include the email, customer and framework patch. The email patch fixes a change introduced by the security patch which may break email template subjects.

Troubleshooting

An error occurred during content generation

The patch changes the way template directives are parsed, this may break certain CMS pages where the content is nested in a Magento 2 translation __(). When one of these content generation errors occur make sure to remove the redundant __() call in your code.
