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.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
