XSS tool that can help you identify and mitigate XSS vulnerabilities is XSStrike. XSS or Cross-Site Scripting is a common web application vulnerability that allows an attacker to inject malicious code into a website, potentially stealing sensitive information from unsuspecting users. XSS attacks can be devastating, and protecting your website against them is essential to ensure the security of your users’ data.
This XSS tool is designed to automate the process of detecting and exploiting XSS vulnerabilities in web applications.
Overview
XSStrike is a Cross Site Scripting detection suite equipped with four hand written parsers, an intelligent payload generator, a powerful fuzzing engine and an incredibly fast crawler. It is automated and advanced XSS tool.
How it Works?
XSStrike works by analyzing a web application for potential XSS vulnerabilities. It does this by sending various payloads to different parts of the application, such as input fields, URLs, and headers, to see if it can trigger an XSS attack. The tool then reports any vulnerabilities it finds, allowing the user to take action to fix them.
Instead of injecting payloads and checking it works like all the other tools do, this tool analyses the response with multiple parsers and then crafts payloads that are guaranteed to work by context analysis integrated with a fuzzing engine. Here are some examples of the XSS payloads generated by XSStrike:
- }]};(confirm)()//\
- <A%0aONMouseOvER%0d=%0d[8].find(confirm)>z
- </tiTlE/><a%0donpOintErentER%0d=%0d(prompt)“>z
- </SCRiPT/><DETAILs/+/onpoINTERenTEr%0a=%0aa=prompt,a()//
Apart from that, XSStrike has crawling, fuzzing, parameter discovery, WAF detection capabilities as well. It also scans for DOM XSS vulnerabilities. Use Arjun to discover hidden parameter on website.

One of the standout features of XSStrike is its ability to detect blind XSS vulnerabilities. These are vulnerabilities that don’t produce any visible effects when a payload is injected, making them harder to detect. XSStrike can detect these types of vulnerabilities by analyzing the network traffic generated by the vulnerable application.
Another useful feature of XSStrike is its ability to bypass various XSS filters. Many web applications use filters to prevent XSS attacks, but these filters can be circumvented using various techniques. XSStrike has a built-in bypass engine that tries various techniques to bypass these filters, allowing it to detect vulnerabilities that other tools might miss.
Install XSStrike
Clone the repository from Github:
After successfully clone the repository, go to the folder and install all the requirements:
Now XSStrike is installed on your machine, run the tool to check if it is installed correctly.
How to Use XSStrike?
Scan a single URL
Test a single webpage which uses GET method.
Supplying POST data
Testing URL path components
Want to inject payloads in the URL path like http://example.com/search/<payload>, you can do that with --path switch.
Blind XSS
Using this option while crawling will make XSStrike inject your blind XSS payload defined in core/config.py to be injected to every parameter of every HTML form.

Using XSStrike is relatively straightforward. The user provides the tool with the URL of the target web application and any additional parameters required for the scan. XSStrike then begins analyzing the application for vulnerabilities. Once the scan is complete, XSStrike generates a report that lists any vulnerabilities it found.
The report includes information about the vulnerability, such as the affected parameter and the payload that triggered the vulnerability. The user can use this information to fix the vulnerability before it can be exploited by an attacker.
