CVE-2019-15132 Information

Description

Zabbix through 4.4.0alpha1 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 incorrect\ and \No permissions for system access\ messages or just blocking for a number of seconds). This affects both api_jsonrpc.php and index.php.
