You can use this firefox addon:

XSS Me

XSS-Me is the Exploit-Me tool used to test for reflected Cross-Site Scripting (XSS). It does NOT currently test for stored XSS.

The tool works by submitting your HTML forms and substituting the form value with strings that are representative of an XSS attack. If the resulting HTML page sets a specific JavaScript value (document.vulnerable=true) then the tool marks the page as vulnerable to the given XSS string. The tool does not attempting to compromise the security of the given system. It looks for possible entry points for an attack against the system. There is no port scanning, packet sniffing, password hacking or firewall attacks done by the tool.

You can think of the work done by the tool as the same as the QA testers for the site manually entering all of these strings into the form fields.

Testing for Reflected Cross Site Scripting

See the example below. Analyze each input vector to detect potential vulnerabilities. To detect an XSS vulnerability, the tester will typically use specially crafted input data with each input vector.

People also ask

What is cross-site scripting (XSS)?

Cross-site scripting (XSS) is a type of vulnerability where the code sent by the attacker is executed back in the user’s browser. The malicious code is written in a scripting language, usually JavaScript. Learn more about cross-site scripting in general.

What are the types of cross-site scripting?

There are three primary types of cross-site scripting vulnerabilities. Stored (persistent) XSS happens when an attacker injects malicious code into the target application – when victims visit the page, their browsers execute this code. Reflected (non-persistent) XSS happens when an attacker uses a malicious phishing link and malicious code is executed as part of the response from the server. DOM XSS happens within the Document Object Model (DOM) of the browser, often with no information sent to the server. Learn more about the types of cross-site scripting.

Is it legal to practice cross-site scripting?

It is completely legal to practice cross-site scripting on sites that are dedicated for that purpose. In this article, you can learn about the most popular sites that are intentionally vulnerable. You can also install your own local vulnerable applications such as bWAPP, OWASP Juice Shop, or DVWA and use them to practice. If you want to see how Acunetix scans vulnerable applications, find out how to configure it with bWAPP.

What is cross-site scripting (XSS) and how to prevent it? | Web Security Academy

The vast majority of XSS vulnerabilities can be found quickly and reliably using Burp Suite's web vulnerability scanner. Manually testing for reflected and stored XSS normally involves submitting some simple unique input (such as a short alphanumeric string) into every entry point in the application, identifying every location where the submitted input is returned in HTTP responses, and testing each location individually to determine whether suitably crafted input can be used to execute arbitrary JavaScript.

Testing for Stored Cross Site Scripting

If the input is escaped by the application, testers should test the application for XSS filters. For instance, if the string “SCRIPT” is replaced by a space or by a NULL character then this could be a potential sign of XSS filtering in action. Many techniques exist in order to evade input filters (see testing for reflected XSS) chapter).

Testing for Reflective XSS | Cobalt

September 18, 2025 - Reflected XSS is a type of Cross-Site Scripting attack where the malicious script is injected via user input and immediately reflected back in the web page’s response. This occurs when input is improperly validated and included in the output without proper encoding. To begin, understand the application's functionality and identify all input vectors, such as URL parameters, forms, and headers. Test these points using simple, unique strings to determine if the input is reflected in the response.

Web App Pentesting: DOM-based XSS Test Case | by @ro0taddict | Medium

March 11, 2025 - The main difference between Reflected and Stored XSS compared to DOM-Based XSS is that in Reflected and Stored XSS, the attacker’s payload is sent to the server at some point — either as part of a request (Reflected) or stored in a database (Stored). In contrast, DOM-Based XSS occurs entirely within the browser, where the malicious script is executed directly in the Document Object Model (DOM) without ever reaching the server.
