LIBRARY : Walkthrough

Today we are going to take a new challenge Library. It is a boot2root challenge where we have to root the server to complete the challenge. You redirect this VM here.

Scanning:

Let’s start off with the scanning process. We used our favorite tool Nmap for port scanning. We found that port 22 and 80 are open.

#nmap -A -sC -sV <target IP>


Enumeration:

As we can see port 80 is open, we opened the IP address in our browser.


We got username: meliodas


Let's explore robots.txt as well.
Little hint as rockyou can be seen.

Exploitation:

Let's hit it (bruteforcing) using hydra..
#hydra -l meliodas -p /usr/share/wordlists/rockyou.txt <target IP> -t 64


we found the password as iloveyou1.

Time for action, as port 22 ssh is open lets get the shell:

#ssh meliodas@<target IP>

Now getting the user flag


To get the root.txt we need to get the root shell of the machine, for this privilege escalation we need to see the permissions:

#sudo -l



We cannot write to this file.

#cat bak.py


This python file import a library named zipfile, so we create a new “zipfile.py” file in the same directory.

#echo 'import os; os.system("/bin/sh")' > zipfile.py

and 

#sudo python /home/meliodas/bak.py

Time to get the final flag




Thank you very much for reading. I hope you find this blog useful.

!!!!Happy Hacking!!!!

  Try Hack Me    Simple CTF Walkthrough Simple CTF  Challenge on TryHackMe Platform is a beginner level CTF, if you want to learn about CTF's, this room is perfect for you! So let’s get going! Initially, let's deploy our machine get connected to THM VPN and then, we are ready to begin. We need to run a Nmap scan against the machine so that we know which ports are open and which services are operational on these ports. I am going to use an aggressive Nmap scan.   #nmap -A -sC -Pn <Target IP> Analyzing the above Nmap scan we now know the number of ports and their associated services that are running on the host. So we have 2 services running under port 1000 and ssh service running on the higher port. Also, as highlighted above, w e see that we have got an anonymous ftp login, let’s try to log in and see if we can find anything. From ftp access as shown above, we are able to gather some information as ForMitch.txt. We will further extract the file and let's see what outp

  Try-hack-me PICKLE-RICK : Walkthrough Today I completed an other room on tryhackme with a Rick and Morty theme to it! Let's go and complete the room Pickle Rick from try Hack Me! Scanning & Enumeration A good rule of thumb is to start by scanning your machine for any open ports.  #nmap -T4 -sC -sV -A -p- <target IP> Enumerating Services Port 22- ssh Here we are able to see that our SSH port is open. This port isn't too vulnerable unless we have found some credentials. So we will not mess with it. Port 80- http It's here where we find a webservice. Lets see if there is anything interesting. This webpage comes up on port 80. There’s no useful data in here. But what if we check the page source? Checking out the source code of a page can reveal all sorts of things.  Great it looks like we have found a user name!!!  Most websites will have a robots.txt file that will tell a browser what is and isn't allowed to index. So lets see if there is one for this site. Su

  Try-hack-me Lian_Yu : Walkthrough This post is a walkthrough of an Arrowverse themed beginner CTF box on Tryhackme. Let’s get started by deploying the machine. Now, after deploying the machine, start with a basic Nmap scan and see which ports and services are open and running on the particular IP address. #nmap -A -sC -sV <target IP> Port 80 is open and running so let’s look at the webpage first.. The First step is to check the page source and robots.txt but no information found there, so let’s move to enumeration. #gobuster dir -u http://<target IP>/ -w /usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt Looks like we have found a directory /island let’s look at it. The webpage looks like this at first instance but when I saw the source code I realized the the code word is also given in as vigilante but is in the white text. So here we got our code word.  I then ran gobuster again with the addition of the new directory I had found directory inside island di
