Duplicate Advisory: Authentication Bypass by CSRF Weakness

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-26xx-m4q2-xhq8. This link is maintained to preserve external references.

Original Description

Impact

CSRF vulnerability that allows user account takeover.

All applications using any version of the frontend component of spree_auth_devise are affected if protect_from_forgery method is both:

• Executed whether as:
  • A before_action callback (the default)
  • A prepend_before_action (option prepend: true given) before the :load_object hook in Spree::UserController (most likely order to find).
• Configured to use :null_session or :reset_session strategies (:null_session is the default in case the no strategy is given, but rails --new generated skeleton use :exception).

That means that applications that haven't been configured differently from what it's generated with Rails aren't affected.

Thanks @waiting-for-dev for reporting and providing a patch 👏

Patches

Spree 4.3 users should update to spree_auth_devise 4.4.1 Spree 4.2 users should update to spree_auth_devise 4.2.1 Spree 4.1 users should update to spree_auth_devise 4.1.1 Older Spree version users should update to spree_auth_devise 4.0.1

Workarounds

If possible, change your strategy to :exception:

class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception
end

Add the following toconfig/application.rb to at least run the :exception strategy on the affected controller:

config.after_initialize do
  Spree::UsersController.protect_from_forgery with: :exception
end
