hunt-http-smuggling

To detect HTTP request smuggling in a CDN-fronted application, you identify parsing inconsistencies between front-end proxies and back-end servers using timing-based probes and protocol-specific desync payloads to confirm exploitability and calculate anomaly risk.

An HTTP desync vulnerability occurs when front-end proxies and back-end servers disagree on request boundaries, allowing attackers to bypass WAF rules, poison caches, or hijack victim sessions by smuggling malicious requests through the proxy stack.

Yes, you can test complex H2-downgrade topologies using h2csmuggler. This skill targets modern infrastructure stacks including CDNs and load balancers, identifying H2.CL and H2.TE desync vulnerabilities alongside traditional CL.TE and TE.CL vectors.

To perform a timing-based probe for TE.CL request smuggling, run a comprehensive HTTP desync scan against the target domain to fingerprint the proxy stack and validate desync vulnerabilities by measuring response delays caused by boundary disagreements.

The best way to verify HTTP request smuggling impact for cache poisoning is to validate exploitability using protocol-specific desync payloads, facilitating complex exploit chains to confirm credential theft or authentication bypass.

Yes, smuggler.py works for detecting parsing inconsistencies in load balancers by targeting complex infrastructure stacks and validating request boundary disagreements between front-end proxies and back-end servers.
