Temple of Doom 1: CTF Walkthrough Part 2

In this article, we’ll continue to solve the Temple of Doom CTF challenge which was posted on VulnHub website by 0katz.

This is the part two of this CTF. In the previous article, we were able to get the limited access shell of the target machine.  As per the VM description by the author on the website, the aim of this CTF is to get the root access of the target machine. In this article, we will learn to get the root access on the target machine and read the flag file. If you have not read the previous part, it is advised to go through the previous installment here.

Please Note: For all of these machines, I have used Oracle Virtual Box to run the downloaded machine. I will be using Kali Linux as the attacker machine for solving this CTF. The techniques used are solely for educational purposes, and I am not responsible if the listed techniques are used against any other targets.

We will be using as the target machine IP address and as the attacker’s IP. Note that these IP addresses may be different on your network, as these are assigned by the DHCP.
