Top 500 Most Important XSS Script Cheat Sheet for Web Application Penetration Testing

XSS is a very commonly exploited vulnerability type which is very widely spread and easily detectable. Here we are going to see about most important XSS Cheat Sheet.

What is XSS(Cross Site Scripting)? An attacker can inject untrusted snippets of JavaScript into your application without validation. This JavaScript is then executed by the victim who is visiting the target site. XSS classified into three types and these XSS Cheat Sheet will help to find the XSS vulnerabilities for Pentesters.

  • Reflected XSS
  • Stored XSS
  • DOM-Based XSS
  • In Reflected XSS, an attacker sends the victim a link to the target application through email, social media, etc. This link has a script embedded within it which executes when visiting the target site.
  • In Stored XSS, the attacker is able to plant a persistent script in the target website which will execute when anyone visits it.
  • With DOM Based XSS, no HTTP request is required, the script is injected as a result of modifying the DOM of the target site in the client side code in the victim’s browser and is then executed.
