Summary

Fanvil x7a firmware version 2.6.0.1182 does not enforce cross-origin resource protection on state-changing requests. The request handler therefore lets an attacker bypass the cross-origin boundary, a flaw classified as CWE-352. A remote attacker without privileges can make a user's browser send forged requests to any endpoint if that user visits attacker-controlled content.
