FreeBSD : logstash -- Remote command execution in Logstash zabbix and nagios_nsca outputs (2184ccad-1a10-11e5-b43d-002590263bf5)

High Nessus Plugin ID 84380


The remote FreeBSD host is missing a security-related update.


Elastic reports :

The vulnerability impacts deployments that use the either the zabbix or the nagios_nsca outputs. In these cases, an attacker with an ability to send crafted events to any source of data for Logstash could execute operating system commands with the permissions of the Logstash process.

Deployments that do not use the zabbix or the nagios_nsca outputs are not vulnerable and do not need to upgrade for this reason.

We have added this vulnerability to our CVE page and are working on filling out the CVE.

We would like to thank Jan Karwowski and Danila Borisiuk for reporting the issue and working with us on the resolution.


Update the affected package.
