What is Cross-Site Scripting reflected?
What is reflected cross-site scripting? Reflected cross-site scripting (or XSS) arises when an application receives data in an HTTP request and includes that data within the immediate response in an unsafe way.
What is the impact of cross-site scripting?
Impact and Risk XSS can have huge implications for a web application and its users. User accounts can be hijacked, credentials could be stolen, sensitive data could be exfiltrated, and lastly, access to your client computers can be obtained.
What are the three types of cross-site scripting?
Cross-site Scripting can be classified into three major categories — Stored XSS, Reflected XSS, and DOM-based XSS.
What’s the difference between stored and reflected XSS?
Stored XSS, also known as persistent XSS, is the more damaging of the two. It occurs when a malicious script is injected directly into a vulnerable web application. Reflected XSS involves the reflecting of a malicious script off of a web application, onto a user’s browser.
Why is it important to prevent XSS attacks?
Cross-site scripting or XSS is a web security vulnerability that allows attackers to run code in your users browsers that the attacker controls. XSS attacks are hard to prevent because there are various vectors where an XSS attack can be used in web applications.
What information can an attacker steal using XSS?

- Stored XSS (AKA Persistent or Type I) Stored XSS generally occurs when user input is stored on the target server, such as in a database, in a message forum, visitor log, comment field, etc.
- Reflected XSS (AKA Non-Persistent or Type II)
- DOM Based XSS (AKA Type-0)
What is an example of cross-site scripting?
Cross-site Scripting (XSS) is a security vulnerability usually found in websites and/or web applications that accept user input. Examples of these include search engines, login forms, message boards and comment boxes. Cybercriminals exploit this vulnerability by inputting strings of executable malicious code into these functions.
What is a reflective cross site scripting attack?

Why is cross-site scripting dangerous?
Why is Cross-site Scripting Dangerous? Cross-site scripting is one of the most common high-risk WordPress vulnerabilities. XSS attacks are so common because, unlike other security vulnerabilities, they are very complex to address. Even when you have built-in protection, it’s very easy to make mistakes that enable cross-site scripting.
