Drupal releases patches for one critical and three moderately critical vulnerabilities

An open-source web content management system, Drupal has released patches for one critical and three moderately critical vulnerabilities.

The critical bug (CVE-2022-25277) impacts Drupal 9.3 and 9.4 and can result in the execution of arbitrary PHP code on the targeted servers.

According to drupal.org, Drupal core sanitizes filenames with dangerous extensions upon upload (reference: SA-CORE-2020-012) and strips leading and trailing dots from filenames to prevent uploading server configuration files (reference: SA-CORE-2019-010).

However, the protections for these two vulnerabilities previously had not worked correctly together. As a result, if the site were configured to allow the upload of files with an htaccess extension, these files’ filenames would not be properly sanitized. This could allow bypassing the protections provided by Drupal core’s default .htaccess files and possible remote code execution on Apache web servers.

“This issue is mitigated by the fact that it requires a field administrator to explicitly configure a file field to allow htaccess as an extension (restricted permission), or a contributed module or custom code that overrides allowed file uploads,” a source as per drupal.org.


Install the latest version:

  • If you are using Drupal 9.4, update to Drupal 9.4.3.
  • If you are using Drupal 9.3, update to Drupal 9.3.19.

All versions of Drupal 9 prior to 9.3.x are end-of-life and do not receive security coverage.
