The code inside this controller calls diableSIDValidation inside the init() method. An attacker doesn't have to know Zabbix user login credentials, but has to know the correct Zabbix URL and contact information of an existing user with sufficient privileges.

Zabbix through 4.4.0alpha1 allows User Enumeration

CVE-2019-15132 5.3 - Medium - August 17, 2019

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.

Side Channel Attack

Multiple cross-site scripting (XSS) vulnerabilities in the formatQuery function in frontends/php/include/classes/class.curl.php in Zabbix before 1.8.3rc1

CVE-2010-2790 - August 05, 2010
