Introduction to Kibana

Kibana is an open source data visualization dashboard for Elasticsearch. It provides visualization capabilities on top of the content indexed on an Elasticsearch cluster. Users can create bar, line and scatter plots, or pie charts and maps on top of large volumes of data.

Testing Kibana for Security Issues

This is a third party software so our goal is to check for the issues that are already known (CVEs) or look for the unauthenticated dashboards, sensitive data exposures, etc.

1. Shodan Dorks to finding Kibana Instances 
a. Dork: title:"kibana" port:"443"
b. Dork: kibana content-length: 217
c. Kibana will return a content length of 217 if it is publicly open and one can access the dashboard without authentication.

2. Google Dorks to find Kibana Instances
a. inurl:app/kibana
b. inurl:app/kibana intext:Loading Kibana
c. inurl::5601/app/kibana

3. Elastic Search Kibana Console LFI (CVE-2018-17246)
