CVE-2018-19148 (opens in a new tab)Amendment
This was deemed not a vulnerability.
Overview
github.com/caddyserver/caddy/v2/caddyhttp/httpserver is an implementation of an HTTP server on top of Caddy.
Affected versions of this package are vulnerable to Information Exposure due to the server's handling of invalid requests. Specifically when it cannot match a Host header with a vhost in its configuration, it serves the X.509 certificate for a randomly selected vhost. Repeated requests with a nonexistent hostname in the Host header allow for the full enumeration of all certificates on the server, thereby enabling an attacker to easily and accurately discover the existence of and relationships among hostnames that were not intended to be public.
