Rukovoditel Cross-Site Request Forgery

Cross Site Request Forgery (CSRF) in Rukovoditel v2.8.3 allows attackers to create an admin user with an arbitrary credentials. (2021-04-29, CVE-2021-30224)

In Rukovoditel 2.5.2 has a form_session_token value to prevent CSRF attacks. This protection mechanism can be bypassed with another user's valid token. Thus, an attacker can change the Admin password by using a CSRF attack and escalate his/her privileges. (2020-04-16, CVE-2020-11818)

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.
