Security Advisories

The tablefield module allows you to attach tabular data to an entity.

The module doesn't sufficiently determine that the data being unserialized is the contents of a tablefield when users request a CSV export, which could lead to Remote Code Execution via Object Injection.

This vulnerability is mitigated by the fact that an attacker must have a role with the permission 'export tablefield', and be able to insert a payload into an entity's field.

This module provides a standardized solution for building API's so that external clients can communicate with Backdrop.

The Services module has an access bypass vulnerability in its "attach_file" resource that allows users who have access to create or update pieces of content that include file fields to arbitrarily reference files they do not have access to, which can expose private files.

This vulnerability is mitigated by the fact that an attacker must have a role with permission to create or edit a piece of content.

This module enables you to add a button that hovers in the bottom of your screen and allows users to smoothly scroll up the page using jQuery.

The module doesn't sufficiently sanitize the code that gets printed on pages leading to a Cross Site Scripting (XSS) issue.

This vulnerability is mitigated by the fact that an attacker must have a role with the permission "access backtotop settings".

Under certain circumstances the File module/subsystem allows a malicious user to upload a file that can trigger a cross-site scripting (XSS) vulnerability.

The Views module included in Backdrop core doesn't sufficiently sanitize certain field types, leading to a Cross Site Scripting (XSS) vulnerability.

This vulnerability is mitigated by the fact that a view must display a field with the format "Full data (serialized)" and an attacker must have the ability to store malicious markup in that field.

Additional information

Note: Backdrop issues individual security advisories for separate vulnerabilities included in a release, rather than lumping "multiple vulnerabilities" into a single advisory. All advisories released today for Backdrop core:

• BACKDROP-SA-CORE-2019-005
• BACKDROP-SA-CORE-2019-006
• BACKDROP-SA-CORE-2019-007

The Views module included in Backdrop core doesn't sufficiently build queries when used with exposed filters, leading to a possible information disclosure vulnerability in certain rare circumstances.

This vulnerability is mitigated by the fact that a view must have an exposed filter on a field that is used on multiple entity types, both of which are included in the view.

The Views module included in Backdrop core doesn't sufficiently protect against argument definitions failing.

This vulnerability is mitigated by the fact that a view must have custom PHP code used as a field validator.

This module addresses the General Data Protection Regulation (GDPR) that came into effect 25th May 2018, and the EU Directive on Privacy and Electronic Communications from 2012. It provides a banner where you can gather consent from the user when the website stores cookies on their computer or otherwise handles their personal information.

The module doesn't sufficiently sanitize data for some interface labels and strings shown in the cookie policy banner, opening up possibility of Cross Site Scripting exploits that can be created by somebody that has access to the admin interface of the module.

This vulnerability is mitigated by the fact that an attacker must have a role with the permission "Administer EU Cookie Compliance banner".

The Ubercart module provides a shopping cart and e-commerce features for Backdrop CMS.

The taxes module doesn't sufficiently protect the tax rate cloning feature. A malicious user could trick a store administrator into duplicating an existing tax rate by getting them to visit a specially-crafted URL.

This module provides a standardized solution for building API's so that external clients can communicate with Drupal.

The module doesn't sufficiently sanitize user input for entity index resources thus allowing SQL Injection attacks.

This vulnerability is mitigated by the fact that the Backdrop site must have an "index" resource(s) enabled under the Services endpoint configuration (admin/structure/services/list/MY-ENDPOINT/resources) and an attacker must know the endpoint's machine name.

Install the 1.x-3.0.3-beta version of the Services module for the fix, or simply disable any "index" resources to stop the attack vector.
