SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Clickjacking testing helps security engineers verify that web applications are protected against UI redress attacks by ensuring proper frame controls.

Core Features & Use Cases

Check X-Frame-Options and CSP frame-ancestors headers across key pages to identify framing vulnerabilities.
Construct and validate lightweight PoC HTML pages that simulate clickjacking scenarios.
Guide remediation planning and risk assessment for both single-page endpoints and multi-step actions.

Quick Start

Run this skill against a target URL to verify framing protections and demonstrate a Clickjacking PoC.

FAQPage Schema

How do I test for clickjacking vulnerabilities on a web application?▼

To test for clickjacking vulnerabilities, check if target pages lack X-Frame-Options or CSP frame-ancestors headers. This process identifies unprotected endpoints and generates PoC HTML templates to demonstrate UI redress attack scenarios safely.

What is the difference between X-Frame-Options and CSP frame-ancestors for preventing framing attacks?▼

X-Frame-Options and CSP frame-ancestors are HTTP response headers preventing clickjacking. X-Frame-Options is older and less flexible, while CSP frame-ancestors provides granular control over allowed framing sources for modern web applications.

How can I create a clickjacking proof of concept for a login page?▼

You can create a clickjacking PoC for a login page by building a lightweight HTML template that embeds the target URL in an iframe. This process generates and validates PoC HTML pages to simulate framing scenarios.

Can I assess clickjacking protections across multi-step account actions?▼

Yes, you can assess clickjacking protections across multi-step account actions. This testing evaluates framing vulnerabilities on sensitive pages and guides remediation planning for both single-page endpoints and multi-step workflows.

What are the limitations of using X-Frame-Options for penetration testing?▼

A limitation of X-Frame-Options in penetration testing is its restricted granularity compared to CSP frame-ancestors. It only supports DENY or SAMEORIGIN directives, lacking fine-grained control over multiple trusted domains for security configurations.
