The +payload travels as **data**, never as part of a shell command line. + +--- + +## 1. Motivation + +The proxy vuln-testers (`proxy-tester-injection` and siblings) confirm and +weaponize findings by constructing `curl` command strings in `bash`. This is +fragile: + +- **Two-layer escaping.** A payload passes through the shell *and* the target + parser.

Core design principle — the "never struggles" guarantee + +> Every request is fundamentally **raw bytes**. A structured convenience layer +> sits on top and round-trips **losslessly** to bytes. If the structured layer +> cannot express something, the agent drops to the **raw-byte backend** and can +> send *any* byte sequence. + +There is therefore **no HTTP message the engine cannot represent**. The +structured layer is ~95% ergonomics; the raw-byte layer is the 5% "nothing is +impossible" escape hatch. Every capability below is built on this two-level +model. + +Two sending backends realize it: + +- **`undici`** (HTTP/1.1 + HTTP/2) — normal requests: auto-encode, connection + pool, fast. Covers the large majority of targets. +- **Raw TCP/TLS socket** (`net` / `tls`) — byte-exact replay for request + smuggling / desync and intentionally-malformed requests, which `undici` + normalizes and thus cannot send. + +Mirrors Caido's `RequestSpec` (structured) / `RequestSpecRaw` (bytes) split. We +do **not** embed Caido (its SDK runs inside Caido; it cannot be imported as a +library and would break clean `npm install`); we copy the design with `undici`. + +--- + +## 3.

Governed concurrency & backpressure (§16) + +Today requests are serial (IngestQueue serial; testers sequential).

New work is admitted as the pool drains. +- **Partial failure** → a host's circuit breaker pauses only that host; others + continue (one failure never stalls the whole run). + +Adaptivity is required: a fixed "N concurrent" guess is either too slow or too +aggressive. AIMD **auto-tunes to the target's real capacity** — gentle on small +targets, fast on large ones. + +--- + +## 6. Phased build (design everything, build in layers) + +- **Phase 1 (P0):** §3.1–3.5 core mutation + both backends + §3.10 response/diff + + §3.11 reliability + §3.12 evidence + `http_replay` / `http_replay_raw`. + → migrates `proxy-tester-injection` off `curl`. +- **Phase 2 (P1):** §3.9 orchestration (race/sequence/battery) + §3.6 TLS/ + transport + §3.8 token/CSRF + §3.13 WebSocket + Intruder modes + §5 governed + concurrency wired into the ingest pipeline. +- **Phase 3 (P2/EXT):** smuggling details + §3.14 import/export + h3/JA3 bridge. + +Every phase is **additive and feature-flagged**. No tester moves off `curl` until +Phase 1 is complete; `curl` stays as fallback throughout. Default behavior is +unchanged while the flag is off. + +--- + +## 7. Non-goals +- Non-HTTP protocols (SMTP/FTP/…): out of scope — this is a web-pentest engine. +- Embedding Caido/Burp: rejected (see §2). Optional import/export only. +- HTTP/3 and JA3 mimicry in core: out (native dependency vs clean `npm install`); + handled by an optional external-tool bridge (detect an installed h3-capable + `curl` / `curl-impersonate`; clean "install X" message when absent — mirrors + how hackbrowser optionally uses Chromium).

From 6a2310a5aba49e2f2fd3637f4c967c561bc9290f Mon Sep 17 00:00:00 2001 From: orhanyildirim Date: Sun, 23 Aug 2026 11:48:02 -0400 Subject: [PATCH 42/62] refactor(scripts): remove 8 Python scripts replaced by http_replay engine MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit LLM + http_replay mutations replace the "loop payloads, send HTTP, check response" pattern these scripts implemented: - cors_checker.py (Origin header → set-header) - response_diff.py (two requests → two http_replay calls + LLM diff) - idor_tester.py (cross-credential → proxy-tester-idor agent) - ssti_tester.py (template payloads → injection agent) - rate_limit_bypass.py (XFF rotation → set-header) - oauth_tester.py (redirect_uri → set-query) - graphql_tester.py (introspection → LLM-crafted queries) - waf_bypass.py (encoding → http_replay encode pipeline) 8 scripts remain: jwt_tamper (crypto), ssrf_listener (callback server), race_tester (async concurrency), file_upload_tester (binary multipart), and 4 recon tools. --- .../cyberstrike/data/scripts/cors_checker.py | 99 ----------- .../data/scripts/graphql_tester.py | 121 -------------- .../cyberstrike/data/scripts/idor_tester.py | 112 ------------- .../cyberstrike/data/scripts/oauth_tester.py | 118 ------------- .../data/scripts/rate_limit_bypass.py | 158 ------------------ .../cyberstrike/data/scripts/response_diff.py | 80 --------- .../cyberstrike/data/scripts/ssti_tester.py | 113 ------------- .../cyberstrike/data/scripts/waf_bypass.py | 84 ---------- 8 files changed, 885 deletions(-) delete mode 100644 packages/cyberstrike/data/scripts/cors_checker.py delete mode 100644 packages/cyberstrike/data/scripts/graphql_tester.py delete mode 100644 packages/cyberstrike/data/scripts/idor_tester.py delete mode 100644 packages/cyberstrike/data/scripts/oauth_tester.py delete mode 100644 packages/cyberstrike/data/scripts/rate_limit_bypass.py delete mode 100644 packages/cyberstrike/data/scripts/response_diff.py delete mode 100644 packages/cyberstrike/data/scripts/ssti_tester.py delete mode 100644 packages/cyberstrike/data/scripts/waf_bypass.py diff --git a/packages/cyberstrike/data/scripts/cors_checker.py b/packages/cyberstrike/data/scripts/cors_checker.py deleted file mode 100644 index 25fb67007..000000000 --- a/packages/cyberstrike/data/scripts/cors_checker.py +++ /dev/null @@ -1,99 +0,0 @@ -#!/usr/bin/env python3 -"""CORS misconfiguration checker — test multiple origin reflection patterns.""" -import argparse -import requests -import json -import sys -import urllib3 -urllib3.disable_warnings() -
