The Maze HTB (Hack The Box) challenge is a popular machine in the HTB platform, known for its complex structure and the rewarding learning experience it offers. This write-up is dedicated to breaking down the Maze HTB challenge step-by-step, offering insights into the techniques and tools used to solve it. The objective is to help both beginners and advanced users understand how to approach this machine, covering everything from initial scanning to exploitation and finally flag extraction.
Hack The Box (HTB) is a platform designed for cybersecurity enthusiasts and professionals to practice penetration testing and ethical hacking. It offers a variety of challenges, from simple to complex, simulating real-world environments where users can sharpen their skills. The Maze HTB challenge is a highly rated machine due to its intricate maze-like structure, which demands both patience and technical expertise.
Overview of the Maze HTB Challenge
Before diving into the technical aspects of solving Maze HTB, it’s essential to understand the overall setup of the machine. The challenge is designed to resemble a maze with multiple layers of security mechanisms that a hacker needs to bypass in order to get to the final flag. Solving the Maze HTB challenge is like solving a puzzle — it requires methodical thinking, precise execution, and the ability to think outside the box.
The machine itself is categorized as an “easy” machine in terms of difficulty, but it still provides significant challenges that can help you hone your skills. The challenge is typically based on a series of clues hidden within the system that guide the user towards finding the flag. These clues require the use of common penetration testing tools, such as nmap, netcat, and reverse shells, as well as knowledge of web servers, file permissions, and vulnerability exploitation.
Initial Enumeration
The first step in solving any HTB machine, including Maze HTB, is enumeration. This involves gathering as much information as possible about the machine’s open ports, services, and running applications. Tools like nmap are essential for this phase. A simple nmap scan using the following command will provide a list of open ports and associated services:
bash
Copy code
nmap -sC -sV <target_IP>
The -sC flag tells nmap to run default scripts, and -sV provides version detection, which can be crucial for identifying vulnerabilities. Maze HTB often features web services running on a specific port, so be on the lookout for any HTTP or HTTPS services. Other common services such as SSH may also be present. Pay attention to these details as they will guide the next steps of the exploitation process.
Web Application Enumeration
Once you’ve identified open web ports, it’s time to explore the web application itself. Maze HTB commonly runs a web-based service that will require users to explore its content and find vulnerabilities. Tools like dirb, gobuster, or nikto can be used to enumerate directories and identify hidden files or vulnerabilities in the web server.
For example, running a gobuster scan with the following command can reveal hidden directories:
bash
Copy code
gobuster dir -u http://<target_IP> -w /usr/share/wordlists/dirb/common.txt
Look for interesting files or paths that may give you clues about potential weaknesses. Pay special attention to any login pages, unusual file extensions, or configuration files that could offer more insights.
Exploiting Vulnerabilities
After gathering information from the enumeration phase, you can start searching for vulnerabilities to exploit. One of the most common vulnerabilities in web applications is Command Injection or SQL Injection, which may allow you to execute arbitrary commands on the server or extract sensitive information from the database. However, each machine on HTB is unique, so it’s essential to apply different approaches.
For Maze HTB, you might find specific vulnerabilities based on the version of the web application or the services running. Once a vulnerability is identified, use the appropriate tool or technique to exploit it. If command injection is possible, you can use tools like netcat or nc to establish a reverse shell:
bash
Copy code
nc -lvnp <your_port>
This will allow you to get a remote shell on the target machine, from which you can explore the filesystem and execute commands.
Privilege Escalation
Privilege escalation is often the next step after obtaining initial access to the machine. In the case of Maze HTB, once you gain access to the web application or a user account, you may need to escalate your privileges to root in order to read the final flag.
Start by exploring the /home directories, /etc/passwd, and other critical system files to look for possible privilege escalation vectors. One common method of privilege escalation is searching for SUID binaries — these are executables that run with the privileges of the file owner (often root). To find SUID binaries, you can use the following command:
bash
Copy code
find / -type f -perm -04000 -ls
Other methods of privilege escalation might include exploiting weak file permissions, kernel vulnerabilities, or even looking for crontab jobs that could allow for privilege escalation.
Finding the Flag
Once you’ve successfully escalated your privileges, the final step is to locate the flag. The flag in Hack The Box challenges is typically stored in a file in the /root directory or another privileged location. The flag is usually in the form of a string, such as:
bash
Copy code
HTB{<your_flag>}
Once you’ve located the flag, you can submit it on the HTB platform to complete the challenge.
Conclusion
Solving the Maze HTB challenge requires patience, persistence, and technical expertise. From initial enumeration to web application analysis, vulnerability exploitation, privilege escalation, and flag retrieval, each phase offers unique learning opportunities. Whether you’re a beginner looking to improve your skills or an experienced hacker fine-tuning your methods, the Maze HTB challenge is an excellent test of your penetration testing abilities.
