## Description

An issue was discovered in phpMyAdmin 4.8.x before 4.8.2, in which an
attacker can include (view and potentially execute) files on the server.
The vulnerability comes from a portion of code where pages are redirected
and loaded within phpMyAdmin, and an improper test for whitelisted pages.
An attacker must be authenticated, except in the
"$cfg['AllowArbitraryServer'] = true" case (where an attacker can specify
any host he/she is already in control of, and execute arbitrary code on
phpMyAdmin) and the "$cfg['ServerDefault'] = 0" case (which bypasses the
login requirement and runs the vulnerable code without any authentication).
