Soy Cms Cross-Site Request Forgery

The SOY Inquiry component of SOY CMS is affected by Cross-site Request Forgery (CSRF) and Remote Code Execution (RCE). The vulnerability affects versions 2.0.0.3 and earlier of SOY Inquiry. This allows remote attackers to force the administrator to edit files once the administrator loads a specially crafted webpage. An administrator must be logged in for exploitation to be possible. This issue is fixed in SOY Inquiry version 2.0.0.4 and included in SOY CMS 3.0.2.328. (2020-09-17, CVE-2020-15182)

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.
