Zabbix is an enterprise IT network and application monitoring solution. In a routine review of its source code, we discovered a CSRF (cross-site request forgery) vulnerability in the authentication component of the Zabbix UI. Using this vulnerability, an unauthenticated attacker can take over the Zabbix administrator’s account if the attacker can persuade the Zabbix administrator to follow a malicious link. This vulnerability is exploitable in all browsers even with the default SameSite=Lax cookie protection in place. The vulnerability is fixed in Zabbix versions 4.0.28rc1, 5.0.8rc1, 5.2.4rc1, and 5.4.0alpha1.
