You should have a running DVWA environment before attempting any of the below. In my previous post I discussed how to set up DVWA inside docker on my black arch system. However, I wont be covering it in this post. This is a type of SQL injection, where we don’t see whether the web application is vulnerable to a injection attack as there is no reply that we can read. This is what we will be using in this blog post. This type utilizes the the UNION SQL operator to combine the results of two or more SELECT statements into a single result.

In summary this post I will go through Learning to beat DVWA sql injection via the web GUI. So DVWA (Dam Vulnerable Web Application) is a web application we can use to learn about Linux exploits that we see in use for common CTF challenges. Continuing in my serious of learning CTF using “Dam Vulnerable Web Application”, lets take a look at DVWA sqli.
