How It Works - step 1

Running the tool xss0r

Managing GET requests with xss0r is straightforward, similar to other commands. For a GET request on a URL, the tool requires a query parameter (e.g., =). Any query with a value is sufficient, as xss0r automatically detects and processes all query parameters in the URL.

Multiple Queries: If the URL contains multiple queries, xss0r sends payloads to each query individually.

Single Query: If there is only one query, all payloads will target that specific query.

Example:
Given a query like artist=1, xss0r will replace the value 1 with XSS payloads to test for vulnerabilities.

xss0r runs on both GET and POST requests, providing an efficient scanning process by analyzing request headers and responses. It employs various advanced techniques to bypass modern WAFs, ensuring thorough security testing. The tool meticulously scans each parameter without missing any potential injection point, guaranteeing comprehensive XSS detection.

How It Works - step 2

Scanning urls with payloads

Once the command is executed, xss0r initiates the scan. During the process, the following information will be displayed:

Confirmed Alerts: Successful detections will be highlighted in green, confirming that the tool has identified a potential XSS vulnerability.

Payload Details: The specific payload used for the detection will be shown.

Targeted URL: The exact URL where the payload was tested will be listed.

Page Title: The title of the target page will be displayed for context.

WAF Detection: If any Web Application Firewalls (WAFs) are identified, they will be reported. This real-time feedback ensures you have complete visibility over the scanning process, helping you track payload performance and security obstacles efficiently.

How It Works - step 3

Opening  Report

Within seconds, a detailed HTML report will be generated, providing essential information about the detected vulnerabilities:

Screenshot: A snapshot of the affected page for visual confirmation.

Payload Used: The exact payload that was deployed.

Affected URL: A clickable link to the targeted URL, allowing you to verify the vulnerability firsthand.
Additionally, a professionally generated report can be downloaded in PDF, CVS and JSON formats, ensuring a comprehensive XSS report for your company. The JSON format allows for seamless integration into your business security workflows and automation tasks.

Frequently Asked Questions

What is an XSS tool, and why do penetration testers utilize it?

An XSS tool is designed to identify Cross-Site Scripting vulnerabilities in web applications. Penetration testers employ these tools to detect security weaknesses that may enable attackers to inject malicious code, thereby enhancing the overall security posture of web applications.

What types of XSS vulnerabilities does the tool detect?

Our tool detects a range of XSS vulnerabilities, including reflected, stored, DOM-based, path-based, blind XSS, as well as vulnerabilities in both GET and POST requests.

How do I customize the payloads?

Our user-friendly interface enables you to effortlessly modify existing payloads or create custom payloads tailored to specific testing scenarios.

Are there any new improvements for WAF bypass?

Yes! We’ve made significant improvements:
+300 new payloads have been added to every plan.
Golden and Business plans now include
500+ new payloads, covering a wide variety of WAFs.
New Fuzzing Feature: This feature performs static analysis based on page source reflection and allowed characters. It generates and automates payloads intelligently, using only the characters allowed by the target application.
Clickable Payloads: xss0r V3 introduces a feature for payloads requiring user interaction, such as <ClickME> buttons. The tool automatically performs POST requests with these payloads, clicks on them, and completes all actions on your behalf.

Is there a trial version available?

Yes, we offer a DEMO service that clients can request at any time, allowing for a 5-day testing period. Additionally, we provide a free access key for new users on the 10th to 15th of every month, enabling them to test the tool before making a purchase, specifically for the PRO plan.

Can xss0r analyze JSON web applications?

Yes, xss0r supports JSON web applications, allowing for detailed testing of JSON payloads and data structures.

What are the advanced search and filter options in xss0r?

xss0r offers advanced search and filter capabilities, allowing users to quickly locate specific vulnerabilities and tailor their testing approach.

What is Blind XSS, and how is it implemented in xss0r?

xss0r now includes Blind XSS functionality, allowing automated testing of reflected vulnerabilities over time. It sends payloads to trigger XSS even in delayed interactions.

Does xss0r V3 support macOS and other Linux distributions?

Yes! xss0r V3 fully supports macOS, Ubuntu (latest version), and is compatible with all Linux platforms.

How does the new crawler feature enhance testing?

The built-in crawler searches through HTML, XML, and JS tags to discover URLs. It also identifies input forms, such as usernames, feedback, and comment fields, and can automatically submit Blind XSS payloads using the new --spray feature.
