## Overview

The request handler of Fanvil x7a firmware version 2.6.0.1182 does not enforce any cross-origin resource protection for any state-changing request performed against the applications. Due to the lack of protection, cross-origin boundary can be completely bypassed, allowing for Cross-Site Request Forgery Attacks against any endpoint.
