DescriptionCVE.org

The Zabbix API host.get action can be exploited by authenticated users to extract a host's PSK key leading to potential loss of data integrity.

AnalysisAI

Zabbix's API host.get action exposes PSK (Pre-Shared Key) credential material to authenticated low-privileged users, allowing extraction of secrets used to secure TLS-encrypted communications between the Zabbix server and monitored agents. Any authenticated API user can query host.get and retrieve PSK values configured on hosts, undermining the confidentiality of those credentials and the integrity of the monitoring infrastructure they protect. …
