Host Header Injection Scanner

Host Header Injection represents a severe threat to modern web applications. When left unpatched, this vulnerability allows attackers to bypass security controls, manipulate application logic, or access sensitive data.

VulnScan utilizes advanced heuristic analysis and active payload testing to accurately identify Host Header Injection across your entire attack surface.

How We Detect Host Header Injection

• Payload Injection — Safely injecting harmless, observable payloads into input vectors
• Behavioral Analysis — Analyzing the application's response anomalies to unexpected data
• Out-of-Band (OOB) Testing — For blind vulnerabilities, we monitor our secure DNS/HTTP listeners for callbacks from your server

How dangerous is Host Header Injection?

Extremely dangerous. Host Header Injection vulnerabilities frequently lead to full system compromise, data breaches, or lateral movement within your internal network.
