# API Reference: Performing CSRF Attack Simulation
|
|
|
|
## HTTP Headers for CSRF Protection
|
|
|
|
| Header | Description |
|
|
|--------|-------------|
|
|
| `Set-Cookie: SameSite=Strict` | Prevents cookie from being sent in cross-site requests |
|
|
| `Set-Cookie: SameSite=Lax` | Allows cookies on top-level GET navigations only |
|
|
| `X-CSRF-Token` | Custom header carrying CSRF token |
|
|
| `Origin` | Sent by browsers on cross-origin POST requests |
|
|
| `Referer` | Indicates the source page of the request |
|
|
|
|
## CSRF Token Patterns (HTML)
|
|
|
|
| Pattern | Framework |
|
|
|---------|-----------|
|
|
| `<input name="csrf_token" value="...">` | Generic |
|
|
| `<input name="csrfmiddlewaretoken">` | Django |
|
|
| `<input name="authenticity_token">` | Ruby on Rails |
|
|
| `<input name="__RequestVerificationToken">` | ASP.NET |
|
|
| `<meta name="csrf-token" content="...">` | Rails/Laravel meta tag |
|
|
|
|
## requests Library
|
|
|
|
| Method | Description |
|
|
|--------|-------------|
|
|
| `session.get(url)` | Fetch page to extract CSRF tokens |
|
|
| `session.post(url, data)` | Submit form with/without CSRF token |
|
|
| `session.cookies` | Access session cookies for SameSite analysis |
|
|
|
|
## Key Libraries
|
|
|
|
- **requests** (`pip install requests`): HTTP client with session cookie management
|
|
- **beautifulsoup4** (`pip install beautifulsoup4`): Parse HTML forms and extract tokens
|
|
- **selenium** (optional): Browser-based CSRF testing with full JS execution
|
|
|
|
## PoC Generation
|
|
|
|
| Element | Purpose |
|
|
|---------|---------|
|
|
| `<form action="target" method="POST">` | Cross-origin form submission |
|
|
| `<input type="hidden">` | Pre-filled form parameters |
|
|
| `document.getElementById().submit()` | Auto-submit on page load |
|
|
| `<img src="target?action=delete">` | GET-based CSRF via image tag |
|
|
|
|
## OWASP Testing Guide
|
|
|
|
| Test ID | Description |
|
|
|---------|-------------|
|
|
| WSTG-SESS-05 | Testing for Cross-Site Request Forgery |
|
