Rundeck Cross-Site Request Forgery

Rundeck is an open source automation service with a web console, command line tools and a WebAPI. Prior to version 3.3.14 and version 3.4.3, a user with `admin` access to the `system` resource type is potentially vulnerable to a CSRF attack that could cause the server to run untrusted code on all Rundeck editions. Patches are available in Rundeck versions 3.4.3 and 3.3.14. (2021-08-30, CVE-2021-39133)

A cross-site request forgery vulnerability in Jenkins Rundeck Plugin allows attackers to connect to an attacker-specified URL using attacker-specified credentials. (2019-10-16, CVE-2019-10454)

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.
