Court of Analysis and Testing

Hi everyone! Welcome back to another vulnhub machine walkthrough. In this post, we will try to solve the the Csharp VulnJSON machine, this particular machine are focus on introducing some key concept of known web application attacks. We will go through each of the vulnerability and we will see how we can elevate this into a working exploit. Background: Setting up this machine is easy, the author provide us with .ova file and all we have to do is just import the file then we good to go.     Information Gathering: first, we need to find out what is the machine ip address, to do this I used nmap to do ping sweep on my local network. from the result above we can see that the target machine is with 192.168.1.7. Now that we have our target IP address, let's proceed with scanning the open port on the machine. cool! so the machine only open port 80 and this will make it much more simple. If we go to the web server, we are welcomed with two forms: first is used for create a user and the oth
