Since this is a binary file and we don’t want to download a file that will not work we would first change our transfer mode to binary and then download the files with the get command. As a side note, if you are having trouble communicating with the ftp server (like I did) go ahead an regenerate your VPN connection file. Listing its contents display a directory named chatserver and navigating through it reveals two files which seem relevant to the application running running on port 9999. With this information we can ftp to the server and see what we can find there, we can connect using the username “ftp” and password “ftp”. If we also take a look at port 21 (FTP) we can see that anonymous login is allowed. Right out from the scan we see that the information obtained from port 9999 contains some information about entering a username and a welcome message to “Brainstorm chat”. Starting out with a TCP scan on nmap, trying to determine the services running and using the “-Pn” switch since the machine doesn’t respond to ICMP. The overall process consisted in obtaining a program that is vulnerable to buffer overflow to then go through the process of making a working buffer overflow POC script on a separate Windows machine and then be used afterwards to gain a shell on brainstorm.

The machine can be found by following this link: Overall Summaryīrainstorm is a machine from TryHackMe to practice buffer overflow on a Windows machine. If you are using a Kali Linux machine you would most likely already have the other tools used in this exercise. This post doesn’t go over the installation of the virtual machine and the other tools used on it, instead here is a list of what is needed to follow through:

In this walk-through I’ll be using a Windows 10 virtual machine to test the buffer overflow script.
