Overview
kibana is an open source (Apache Licensed), browser-based analytics and search dashboard for Elasticsearch.
Affected versions of this package are vulnerable to HTTP Request Smuggling via inconsistent parsing of HTTP requests. An attacker can access confidential responses intended for other authenticated users by exploiting differences in HTTP request interpretation between front-end proxies and the backend service.
Note: This is only exploitable if specific proxy deployment configurations are in place that allow such inconsistent interpretation.
