Hack the Box (HTB) machines walkthrough series — Networked

Today, we will be continuing with our exploration of Hack the Box (HTB) machines, as seen in previous articles. This walkthrough is of an HTB machine named Networked.

HTB is an excellent platform that hosts machines belonging to multiple OSes. It also has some other challenges as well. Individuals have to solve the puzzle (simple enumeration plus pentest) in order to log into the platform and download the VPN pack to connect to the machines hosted on the HTB platform.

The walkthrough

Note: Only write-ups of retired HTB machines are allowed. The machine in this article, named Networked, is retired.

Let’s start with this machine.

1. Download the VPN pack for the individual user and use the guidelines to log into the HTB VPN.

2. The “Networked” machine IP is 10.10.10.146.

3. We will adopt the usual methodology of performing penetration testing. Let’s start with enumeration in order to learn as much about the machine as possible.

4. As usual, let’s start with the nmap scan to gather more information about the services running on this machine. [CLICK IMAGES TO ENLARGE]
<<nmap -sC -sV -oA Networked 10.10.10.146>>

5. Ports 22, 80 and 443 are discovered. I couldn’t find any direct information from port 80, so let’s start port enumeration on this server.
<<gobuster -u http://10.10.10.146 -w /usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt -t 20>>

6. As we can see, there are some interesting directories enumerated. Let’s see what is in backup.
Below, we can see a tar file.

7. Let’s download it and extract it.

8. Let’s see what’s in index.php. Oh, good! There’s a message written there!

9. In upload.php, we can see that it uploads the file based on extension and MIME.

10. So now we can create (Read more...)
