Host Header Injection Scanner
Tests for host header manipulation in password reset and routing.
What is Host Header Injection?
Host header injection occurs when applications trust the Host header for generating URLs in password reset emails, OAuth callbacks, or caching. Attackers can manipulate this header to redirect password resets to their domains, poison caches, or access virtual hosts.
Why is This Important?
Host header attacks can capture password reset tokens by making applications send reset links to attacker-controlled domains. This leads to account takeover without any user interaction beyond requesting a password reset.
How It Works
1. Web Crawling
Intelligent crawling discovers all endpoints, forms, parameters, and dynamic content across your web application.
2. Payload Injection
AI-powered payloads test each input vector for web vulnerabilities with context-aware attack patterns.
3. Response Analysis
Advanced analysis detects vulnerability signatures in responses, confirming exploitability with proof-of-concept.

Frequently Asked Questions
How does password reset poisoning work?
Attacker requests password reset for victim, manipulates Host header to their domain. Reset email contains a link to attacker's domain. When victim clicks, attacker captures the reset token.
What other attacks use Host header injection?
Cache poisoning (serving different content), accessing internal virtual hosts, SSRF-like attacks where the application makes requests to the specified host, and web cache deception.
Why do applications trust the Host header?
It's often used to generate absolute URLs, determine which virtual host to serve, or decide which database to query in multi-tenant applications. Developers assume it's trustworthy.
How do I prevent Host header attacks?
Whitelist allowed Host values, use hardcoded domain for sensitive URLs (password resets), and validate Host against expected values in server configuration.
