What is cross-site scripting attacks?
Cross-Site Scripting (XSS) attacks are a type of injection, in which malicious scripts are injected into otherwise benign and trusted websites. XSS attacks occur when an attacker uses a web application to send malicious code, generally in the form of a browser side script, to a different end user.
How does cross-site scripting attack work?
Cross-site scripting works by manipulating a vulnerable web site so that it returns malicious JavaScript to users. When the malicious code executes inside a victim’s browser, the attacker can fully compromise their interaction with the application.
Which is an example of a cross-site scripting XSS attack?
Examples of reflected cross-site scripting attacks include when an attacker stores malicious script in the data sent from a website’s search or contact form. A typical example of reflected cross-site scripting is a search form, where visitors sends their search query to the server, and only they see the result.
What are the three different types of cross-site scripting XSS attacks?
Cross-site Scripting can be classified into three major categories — Stored XSS, Reflected XSS, and DOM-based XSS.
- Stored XSS (Persistent XSS) The most damaging type of XSS is Stored XSS (Persistent XSS).
- Reflected XSS (Non-persistent XSS)
- DOM-based XSS.
- XSS Discovery and Prevention.

What is CSRF attack example?
In a successful CSRF attack, the attacker causes the victim user to carry out an action unintentionally. For example, this might be to change the email address on their account, to change their password, or to make a funds transfer.
What is the difference between DOM XSS and reflected XSS?
While DOM-based XSS occurs by processing data from an untrusted source by writing data to a potentially dangerous sink within the DOM, reflected XSS occurs when an application obtains data in an HTTP request and includes that data within the immediate response in an unsafe way.
How does a cross site scripting attack work?
