This is likely what the query looks like on the backend, with first_name and surname being the selected columns, for a total of two columns. To make this clearer, let's take a look at what the query would look like during normal submission of input: select first_name, surname from users where user_id='' This will allow us to reliably exploit a union-based injection flaw in just a bit. The next thing we need to do is enumerate the database and determine the number of columns in use. The first thing we need to do is log in to DVWA using the default credentials, admin as the username and password as the password. Luckily, there is a lot of good information available to begin down the path. Although this type of attack is one of the easiest to get started with, SQL injection can take years to truly master. There are many different types of SQL injection and different attack methods for the various database systems in use.
RAN ONLINE PRIVATE SERVER SQL INJECTION CODE
Attackers can inject malicious SQL code in order to extract sensitive information, modify or destroy existing data, or escalate the attack in an attempt to own the server.

SQL injection is one of the most common vulnerabilities encountered on the web and can also be one of the most dangerous. If you're new to Kali, we recommend you follow our guide on getting Kali set up and secured, to make sure your system is ready for anything. We will be using DVWA, an intentionally vulnerable virtual machine, and Kali Linux to carry out our attack. As a lesson, we'll be exploiting a simple SQL injection flaw to execute commands and ultimately get a reverse shell on the server. SQL injection is typically only associated with databases and their data, but it can actually be used as a vector to gain a command shell. One of the ultimate goals in hacking is the ability to obtain shells in order to run system commands and own a target or network.
