Enumeration

SEA is an easy Linux machine. I will show here a step by step walkthrough on how to pwn this box.

1. First thing first. Copy the IP address into the /etc/hosts file.

2. Run an Nmap scan on the target machine.

The results of the nmap scan shows that it has open TCP port 80 and SSH port 22. We know that the SSH is not of use for us at the moment. But since we have a port 80 open. We will try and open that in the browser.

3. Typing http://sea.htb:80

4. Clicking on the HOW TO PARTICIPATE will scroll down to this page.

5. Notice the blue link “contact” clicking that link will bring us to a registration page.

NOTE: This is a “/contact.php” page

6. At this point, we may have to perform fuzzing to further enumerate the existence of sub-directories.

7. Our tool of choice for this is FFUF- a fast web fuzzer written in Go that allows typical directory discovery, virtual host discovery (without DNS records) and GET and POST parameter fuzzing.

NMAP

As usual, we begin our enumeration using an nmap scan of the target machine.

1. Add the IP address to your etc/hosts file.

                       echo ” 10,10.xxxx.xxxx chemistry.htb” | sudo tee -a /etc/hosts

     2.  Start NMAP scan.

nmap -p- -A-  Chemistry.htb 

 

3. There is a TCP at port 5000.

These skills form the foundation of success in tackling cybersecurity challenges like MonitorsThree on HackTheBox.

Gaining the Initial Foothold on MonitorsThree

Securing an initial foothold on MonitorsThree is a crucial first step that sets the stage for uncovering deeper layers of vulnerabilities. Like many CTF challenges, MonitorsThree requires a combination of enumeration, reconnaissance, and sharp attention to detail. Begin by thoroughly scanning the machine to identify open ports, services, and any public-facing applications. This foundational work can reveal overlooked entry points or misconfigurations, giving you an early advantage.

Next, employ various enumeration tools such as Nmap and Gobuster to uncover hidden directories, files, or subdomains. Take note of any services running on unusual ports, as these may be configured with weak security measures or outdated software versions. By examining these potential weak points, you can often find low-hanging vulnerabilities that allow for an initial shell or limited access to the system.

Once you’ve established this initial access, further enumeration within the machine becomes key to moving forward. Look for misconfigured services, plaintext credentials, or files with excessive permissions that can be leveraged to escalate privileges. With persistence and the right approach, this initial foothold on MonitorsThree can be secured, setting the stage for further exploration and eventual capture of the user flag.

NMAP

I used Nmap scan to perform enumeration on the target machine.

 

nmap -sC -sV -oN monitorsthree.htb 10.10.xxx.xxx

 

There is a TCP port 80 We can try and open that link. http://monitorsthree.htb
