Multiple vulnerabilities were discovered in Zabbix, a network monitoring solution. An attacker may enumerate valid users and redirect to external links through the zabbix web frontend.
Zabbix allows User Enumeration. With login requests, it is possible to enumerate application usernames based on the variability of server responses (e.g., the
Login name or password is incorrectand
No permissions for system accessmessages, or just blocking for a number of seconds). This affects both api_jsonrpc.php and index.php.

This update also includes several other bug fixes and improvements. For more information please refer to the upstream changelog file.
