The site errors out and says “Extension not allowed”, so how do we get past it? Create an empty file and try uploading it to the page, here we run into our first problem.

Being able to upload malicious files and executing that code means we can spawn a reverse shell into the web server machine. Great news! It looks like a file upload page. Use whichever method you find suits your style the best, there is no one method to do things.Īn internal uploads page on the web server

There has been times where a full scan would take an upwards of 40 minutes to finish, so I find this to be more efficient. This ensures I don’t miss anything without having to sit around waiting for the full scan finish. I personally like to run a quick scan of the top 1000 most common ports, then run another scan of all the ports while I start researching on the info I got in the previous scan. The -A flag encompasses a log of the other individual scan flags, so it’s my go-to option for these types of scans. The room provides more option flag information, so I’ll just be documenting the ones I use. This can be useful if nmap says the host seems down when using a regular scan

Treat the target as online (skip host discovery). You can use it to receive updates about the scan process and other information while nmap is running Will perform all available scans: OS detection, version detection, script scanning, and traceroute. If you don’t use this option, nmap will scan the top 1000 most common ports Using the option -p- will scan all ports from 1-65535. Enumeration is arguably the most important step in pentesting, information is everything when you’re trying to find vulnerabilities. It will show us open ports and information about the services, not totally accurate but it does give us a good idea of what we’re up again. Nmap is a handy network scanner tool that’s bundled in with both Kali and Parrot, it can be used to identify what services are running on the target system which gives us more surface area for us to exploit later. If you ever feel crunched on time, just add 1 hour to the expiration countdown (will work anytime the machine has less than 1 hour left), so don’t stress out too much and make sure you understand each section. Once your machine is deployed, the page will display your unique box IP address to start working on. You may notice I use sudo for many commands, this is not necessary if you’re running Kali OS as the root user. NOTE: I will be using Parrot OS as my preferred pentesting environment. Let’s get started by deploying the box then! This room was how I got my feet wet in the world of pentesting, so we’ll be learning together. I highly recommend completing this room before moving onto intermediate boxes, especially if you’re relatively new to the different tools available. The room will provide basic information about the tools require with the guided sections, but will also require some outside research. Vulnversity is a great guided beginner room created by TryHackMe. We save the hard drive image to a file.F*NG InfoSec Vulnversity Walkthrough The pv command allows a user to see the progress of data through a pipeline. If you don't redirect stdout the data received will be printed on screen. Netcat will start to listen on the port 9999 and the result will be save to the received_file.txt.

Receiving side nc -l -p 9999 > received_file.txt You will have one netcat that will send data and the other one for receiving. if you want to send confidential information you should encrypt your data before sending it to the network. Usually people transfer files using SCP, FTP, SMB but sometimes you don't want to waste time configuring a service.

Learning this tool is a must have skill for any devops, it or software developer. Netcat is a helpful tool when you are in a hurry to transfer files between machines.
