Description

Kibana versions before 5.6.15 and 6.6.1 contain an arbitrary code execution flaw in the Timelion visualizer.
An attacker with access to the Timelion application could send a request that will attempt to execute
javascript code. This leads to an arbitrary command execution with permissions of the
Kibana process on the host system.

Exploitation will require a service or system reboot to restore normal operation.

The WFSDELAY parameter is crucial for this exploit. Setting it too high will cause MANY shells
(50-100+), while setting it too low will cause no shells to be obtained. WFSDELAY of 10 for a
docker image caused 6 shells.

Tested against kibana 6.5.4.
