If they can submit a clever enough request, they can not only see the back menu, but also change it! An attacker could exploit this vulnerability to run any code on the server, potentially leading to unauthorized access, data theft, or even complete control of your Exchange environment. This is absolutely devastating if left unaddressed, as it puts your entire organization at risk!
