The XSS-Scanner is a tool designed to detect cross-site scripting (XSS) vulnerabilities, widely recognized as among the most common and severe web application security weaknesses.

These vulnerabilities are so significant that they are given their chapter in the OWASP Top 10 project and are actively sought after by many bug bounty programs.

What is XSS(Cross-Site Scripting )?

Without proper validation, an attacker can inject untrusted snippets of JavaScript into your application. Then, when a victim visits the target site, this JavaScript is executed, putting the victim’s security at risk.

• Reflected XSS
• Stored XSS
• DOM-Based XSS

Reflected XSS is an attack where the attacker sends a link to the victim via email, social media, or other means. This link contains a script executed when the victim visits the target application.

Stored XSS is an attack in which the attacker can implant a script into the target website that persists over time. This script will execute whenever anyone visits the site, potentially compromising their security.

DOM Based on XSS is an attack that does not require an HTTP request. Instead, the script is injected into the client-side code of the target site by modifying the DOM in the victim’s browser. Once injected, the script is executed, potentially compromising the victim’s security.

XSS Automation Tool

This tool is intended for educational purposes and is designed to assist users in identifying and exploiting cross-site scripting (XSS) vulnerabilities in web applications.

When an application fails to sanitize user-supplied data included in its responses properly, XSS vulnerabilities can arise.

This can allow an attacker to inject malicious code into the response, which is then executed by the victim’s browser, compromising their security.

Requirements

The tools need Python 3.6 or newer version installed

Installation

To install the XSS automation tool;

git clone https://github.com/EmperialX/XSS-Automation-Tool.git

Usage

To use the XSS automation tool;

python xss_scanner.py http://example.com xss_payloads.txt reflected url get base64

Write the Payloads to a Text File

create your payloads to a text file:

xss_payloads = [

]
with open(‘xss_payloads.txt’, ‘w’) as f:
for payload in xss_payloads:
f.write(payload + ‘\n’)

It creates the payload file ss_payload.txt.
