E-mail Newsletter Management Cross-Site Request Forgery

Cross-site request forgery (CSRF) vulnerability in EC-CUBE plugin 'Mail Magazine Management Plugin' ver4.0.0 to 4.1.1 (for EC-CUBE 4 series) and ver1.0.0 to 1.0.4 (for EC-CUBE 3 series) allows a remote unauthenticated attacker to hijack the authentication of an administrator via a specially crafted page, and Mail Magazine Templates and/or transmitted history information may be deleted unintendedly. (2022-02-24, CVE-2022-21179)

The absence of Anti-CSRF tokens may lead to a Cross-Site Request Forgery attack that can result in executing a specific application action as another logged in user, e.g. steal their account by changing their email and password or silently adding a new admin user account when executed from the administrator account.

The attacker may copy one of your web application forms, e.g. email/password change form.

The webpage will contain a form with the exact set of fields as the original application but with input values already provided and the submit button replaced with a Javascript code causing auto-submission. When the page is accessed the form will be immediately submitted and page contents replaced with a valid content or a redirect to your original application.

One of your application users who is already logged in can be then tricked to navigate to such malicious page e.g. by clicking a link in a phishing email, and the pre-populated form content will be submitted to your application like it would be submitted by your user.
