preventing external service interaction (DNS) apache2

How can i eliminate this issue in Apache, perhaps some help with settings in [url removed, login to view]

some settings in apache which i can do to eliminate External Service Interaction (DNS)

It is possible to induce the application to perform server-side DNS lookups of arbitrary domain names.

The payload [url removed, login to view] was submitted in the SSL

SNI value and the HTTP Host header.

The application performed a DNS lookup of the specified domain.

If the ability to trigger arbitrary external service interactions is not intended behavior, then you should

implement a whitelist of permitted services and hosts, and block any interactions that do not appear on this whitelist.

Skills: Apache, DNS, Linux, MySQL, PHP
