How To Scan XSS vulnerability of Web Applications using XSpear
Cross-site scripting.

One of the major vulnerabilities found in web applications.

If you own a web application you should know how to scan for XSS vulnerability. If you do not own a web application, still, knowing about it will help you in the future.

What is Cross-site scripting?

Cross-site scripting is a technique in which attackers inject malicious scripts into a target web application and may allow them to gain access control of the web application but it will differ depending on the type of Cross-site attack. If the attacker injects a Javascript, this could allow him/her to interact with the cookies. This is the specialty of Java script.

What do we have in cookies? we have saved passwords, or the attacker can redirect the victim to a phishing website.

There are mainly three types of Cross-site scripting attacks.
  1. Reflected XSS
  2. Stored  XSS
  3. DOM XSS

Here, we are going to scan a website for XSS vulnerability. The tool going to be used here is called XSpear which is written in GEM and very powerful.

Let's see how we can configure XSpear in Kali Linux.

Configuring XSpear in Kali Linux

Fire up your Kali Linux machine and download XSpear from Github. Navigate to the directory where you have downloaded it and expand it.

Now its time to start the installation process.

1.  Make sure you have Gem installed in your machine. Launch the XSpear script with the command-

gem install XSpear-1.3.1.gem

Most hackers are young because young people tend to be adaptable. As long as you remain to be adaptable, you can always be a good hacker. - Emmanuel Goldstein     ~Click here to tweet~

Conclusion

Cross-site scripting has always been a powerful attack for hackers. This attack is just basically a Game of Codes!

You have good knowledge of different web-based programming languages, you found a website with XSS vulnerability, then play with it.
