Drupal Core - Multiple Vulnerabilities - SA-CORE-2017-004

Drupal Core Security - Wed, 08/16/2017 - 12:38

Drupal 8.3.7 is a maintenance release which contain fixes for security vulnerabilities.

Updating your existing Drupal 8 sites is strongly recommended (see instructions for Drupal 8). This release fixes security issues only; there are no new features nor non-security-related bug fixes in this release. See the 8.3.7 release notes for details on important changes and known issues affecting this release. Read on for details of the security vulnerabilities that were fixed in this release.

Description Views - Access Bypass - Moderately Critical - Drupal 8 - CVE-2017-6923

When creating a view, you can optionally use Ajax to update the displayed data via filter parameters. The views subsystem/module did not restrict access to the Ajax endpoint to only views configured to use Ajax. This is mitigated if you have access restrictions on the view.

It is best practice to always include some form of access restrictions on all views, even if you are using another module to display them.

REST API can bypass comment approval - Access Bypass - Moderately Critical - Drupal 8 - CVE-2017-6924

When using the REST API, users without the correct permission can post comments via REST that are approved even if the user does not have permission to post approved comments.

This issue only affects sites that have the RESTful Web Services (rest) module enabled, the comment entity REST resource enabled, and where an attacker can access a user account on the site with permissions to post comments, or where anonymous users can post comments.

Entity access bypass for entities that do not have UUIDs or have protected revisions - Access Bypass - Critical - Drupal 8 - CVE-2017-6925

There is a vulnerability in the entity access system that could allow unwanted access to view, create, update, or delete entities. This only affects entities that do not use or do not have UUIDs, and entities that have different access restrictions on different revisions of the same entity.

Versions affected

Drupal Core - Multiple Vulnerabilities - SA-CORE-2017-003

Drupal Core Security - Wed, 06/21/2017 - 13:44

Drupal 8.3.4 and Drupal 7.56 are maintenance releases which contain fixes for security vulnerabilities.

Updating your existing Drupal 8 and 7 sites is strongly recommended (see instructions for Drupal 8 and for Drupal 7). This release fixes security issues only; there are no new features nor non-security-related bug fixes in this release. See the 8.3.4 release notes and the 7.56 release notes for details on important changes and known issues affecting this release. Read on for details of the security vulnerabilities that were fixed in this release.

  • Advisory ID: DRUPAL-SA-CORE-2017-003
  • Project: Drupal core
  • Version: 7.x, 8.x
  • Date: 2017-June-21
  • Multiple vulnerabilities
Description PECL YAML parser unsafe object handling - Critical - Drupal 8 - CVE-2017-6920

PECL YAML parser does not handle PHP objects safely during certain operations within Drupal core. This could lead to remote code execution.

File REST resource does not properly validate - Less Critical - Drupal 8 - CVE-2017-6921

The file REST resource does not properly validate some fields when manipulating files. A site is only affected by this if the site has the RESTful Web Services (rest) module enabled, the file REST resource is enabled and allows PATCH requests, and an attacker can get or register a user account on the site with permissions to upload files and to modify the file resource.

Files uploaded by anonymous users into a private file system can be accessed by other anonymous users - Moderately Critical - Drupal 7 and Drupal 8 - CVE-2017-6922

Private files that have been uploaded by an anonymous user but not permanently attached to content on the site should only be visible to the anonymous user that uploaded them, rather than all anonymous users. Drupal core did not previously provide this protection, allowing an access bypass vulnerability to occur. This issue is mitigated by the fact that in order to be affected, the site must allow anonymous users to upload files into a private file system.

The security team has also received reports that this vulnerability is being exploited for spam purposes, similar to the scenario discussed in PSA-2016-003 for the public file system.

Versions affected
  • Drupal core 7.x versions prior to 7.56
  • Drupal core 8.x versions prior to 8.3.4
