2fa Enterprise Server Cross-Site Request Forgery

A CSRF issue in WiKID 2FA Enterprise Server through 4.2.0-b2053 allows a remote attacker to trick an authenticated user into performing unintended actions such as (1) create or delete admin users; (2) create or delete groups; or (3) create, delete, enable, or disable normal users or devices. (2019-10-17, CVE-2019-17118)

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.
