# Pentesting Elasticsearch (port 9200)
## When to Use
- Default `9200/tcp` (REST/HTTP API), `9300/tcp` (node-to-node transport).
- Accessed over **HTTP** — browsing `http://<IP>:9200/` returns a JSON banner (cluster name, version, Lucene version).
- Use whenever 9200 is reachable — Elasticsearch ships with **authentication disabled by default**, exposing all indices.
## Quick Enumeration
```bash
# Banner / version
curl -s http://<IP>:9200/
# Auth posture check
curl -s -X GET "http://<IP>:9200/_xpack/security/user"
