Descriptions

After the initial setup process, some steps of setup.php file are reachable not only by super-administrators, but by unauthenticated users as well. Malicious actor can pass step checks and potentially change the configuration of Zabbix Frontend.

Después del proceso de configuración inicial, algunos pasos del archivo setup.php son accesibles no sólo para los superadministradores, sino también para los usuarios no autenticados. Un actor malicioso puede pasar las comprobaciones de los pasos y potencialmente cambiar la configuración de Zabbix Frontend

An update that solves three vulnerabilities and has two fixes is now available. This update for zabbix fixes the following issues. Fixed possible view of the setup pages by unauthenticated users if config file already exists. Fixed CSRF protection mechanism inside CControllerAuthenticationUpdate controller. Fixed stored XSS in the URL Widget.

Malicious actors can pass step checks and potentially change the configuration of Zabbix Frontend.
