API Reference: HTTP Request Smuggling Detection Agent
Dependencies
| Library | Version | Purpose |
|---|---|---|
| requests | >=2.28 | Architecture fingerprinting via HTTP headers |
| socket/ssl | stdlib | Raw HTTP request construction for smuggling probes |
CLI Usage
python scripts/agent.py --url https://target.example.com/ --output smuggling.json
Functions
identify_architecture(url) -> dict
Sends a GET request and inspects Server, Via, X-Served-By, CF-Ray headers to identify proxy/CDN chain.
send_raw_request(host, port, request_bytes, use_ssl, timeout) -> tuple
Low-level socket send for crafting ambiguous HTTP requests. Returns (response_bytes, elapsed_seconds, error).
test_clte_detection(host, port, use_ssl) -> dict
Sends a CL.TE probe with mismatched Content-Length and incomplete chunked body. A response delay >5s suggests vulnerability.
test_tecl_detection(host, port, use_ssl) -> dict
Sends a TE.CL probe. Back-end reading Content-Length receives extra data that becomes the next request prefix.
test_te_te_detection(host, port, use_ssl) -> dict
Tests 5 Transfer-Encoding header obfuscation variants to detect differential parsing.
run_assessment(url) -> dict
Orchestrates all tests and compiles results.
Smuggling Types
| Type | Front-End Uses | Back-End Uses | Detection |
|---|---|---|---|
| CL.TE | Content-Length | Transfer-Encoding | Time delay on incomplete chunk |
| TE.CL | Transfer-Encoding | Content-Length | Extra data becomes next request |
| TE.TE | Transfer-Encoding | Transfer-Encoding | Obfuscated TE header parsed differently |
