URL Redirect

hello ,

I would like to report a fault in the request parameter , it allows redirection to external links from happening , which would make it possible for an attacker , using the suitability of the field with zabbix application, phishing attacks.

Example:

Normal request :

http: //server/zabbix/index.php?request=hosts.php

Malicious request :

http: //server/zabbix/index.php?request=http://fakepage/hosts.php

POC attached a video.
