On an Asus router you can configure wifi guest networks to have no access to your intranet. However, it's trivial for a guest to gain access to your full network and even retrieve your main wifi password (because once you're on the intranet, the router is happy to tell you via its config sharing daemon).
I found three ways to bypass that limitation but the one I'm trying to report doesn't even require any technical skills and has been discussed elsewhere already [1].
What can I do at this point to be taken seriously? Create a CVE? Is this something someone with no background in security can do?
