zabbix: JavaScript preprocessing, webhooks and global scripts can cause uncontrolled CPU, memory, and disk I/O utilization
CVE-2023-29449 is fixed in zabbix on 1 platform, first by DEBIAN-CVE-2023-29449, released July 13, 2023. It is not reported as exploited. Patch Radar priority: Routine.
JavaScript preprocessing, webhooks and global scripts can cause uncontrolled CPU, memory, and disk I/O utilization. Preprocessing/webhook/global script configuration and testing are only available to Administrative roles (Admin and Superadmin). Administrative privileges should be typically granted to users who need to perform tasks that require more control over the system. The security risk is limited because not all users have this level of access.
