| Type | Key Vectors |
|---|---|
| SSRF | Internal service access, cloud metadata, protocol smuggling |
| HTTP Smuggling | CL.TE, TE.CL, TE.TE, CL.0, H2.CL, h2c, multi-layer proxy chains, connection pooling desync |
| Path Traversal | Directory traversal, null bytes, encoding bypass |
| File Upload | Extension bypass, content-type manipulation, polyglot files |
| Deserialization | Java, PHP, Python, .NET gadget chains |
| Host Header | Password reset poisoning, cache poisoning, routing-based SSRF |
| CUPS / cups-browsed | CVE-2024-47076/47175/47176/47177 — UDP browse → IPP injection → PPD injection → foomatic-rip RCE (see skills/infrastructure/reference/scenarios/network-recon/cups-browsed-rce.md) |

Guides SSRF penetration testing in web apps: identifies URL input risks, exploits internal/cloud metadata access, blind SSRF via OOB, bypasses like IP tricks/DNS rebinding, checklists, and impact evaluation.
Tests file upload endpoints for RCE, XSS, SSRF, and path traversal. Covers 10 bypass techniques including extension tricks, magic bytes, XXE in DOCX, and ZIP slip.
