Nice! Looks like we were able to establish a connection! From here, I began to enumerate the files and folder on the share. For any of the files I found, I went ahead and used the get command to download it back to my host, just like in FTP. | Nice! Looks like we were able to establish a connection!

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

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.

Nice! Looks like we were able to establish a connection! From here, I began to enumerate the files and folder on the share. For any of the files I found, I went ahead and used the get command to download it back to my host, just like in FTP.

Once we are done with kathy’s share, we can go ahead and login to the tmp share and do the same.

Out of the files we got, we had a WordPress Backup, a FTP Configuration file, an LS file, and a to-do-list.
Let’s open to-do-list.txt and the ls file to see if we can’t find anything interesting.
root@kali:~# cat to-do-list.txt
I'm making sure to backup anything important for Initech, Kathy
root@kali:~# cat ls .: total 12.0K drwxrwxrwt 2 root root 4.0K Jun 5 16:32 . drwxr-xr-x 16 root root 4.0K Jun 3 22:06 .. -rw-r--r-- 1 root root 0 Jun 5 16:32 ls drwx------ 3 root root 4.0K Jun 5 15:32 systemd-private-df2bff9b90164a2eadc490c0b8f76087-systemd- timesyncd.service-vFKoxJ
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.
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.
root@kali:~# nikto -h 192.168.1.13:12380

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!
User-agent: * Disallow: /admin112233/ Disallow: /blogblog/
From here, I decided to try and navigate to /admin112233/ as it seemed the most interesting to me.
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!
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
import ssl ssl._create_default_https_context = ssl._create_unverified_context Once it ran successfully - I navigated to https://192.168.1.13:12380/blogblog/wp-content/uploads/ and was presented with a .jpeg file.
