#!/usr/bin/env python # -*- coding: utf-8 -*- """ Copyright (c) 2006-2026 sqlmap developers (https://sqlmap.org) See the file 'LICENSE' for copying permission Adversarial "shitty response" JITTER harness for BOOLEAN-based blind extraction. Boolean-blind decides each bit through the REAL comparison() oracle (--string / --not-string / --regexp / --code / page-ratio). In the wild a target throws transient junk between good responses - gateway 5xx, WAF/rate-limit pages, a Cloudflare "just a moment" interstitial, a captcha, a maintenance banner, a truncated or empty body, an A/B variant, even a page that COINCIDENTALLY contains the --string token (a direction-flipping false positive). This drives the REAL bisection() + REAL comparison() + REAL validateChar() re-validation against a mock oracle that injects that catalog (IID or in bursts) at controllable rates, with NO network, fully deterministic per seed. The template is PAYLOAD_DELIMITER-wrapped so validateChar's per-char '!=' re-check actually fires (the same fidelity trap the time-based harness hit), and the mock sets threadData.lastCode so the unexpectedCode -> validateChar defense engages exactly as in a live run. Two tiers (mirrors tests/test_jitter_stress.py): * TestBooleanJitterRegression - ALWAYS runs. Deterministic, non-flaky guards: clean extraction is perfect, benign dynamic content never corrupts, and a transient unexpected-code response landing on a validation request is ridden out. * TestBooleanJitterSweep - OPT-IN (SQLMAP_JITTER_STRESS=1). The creative failure-surface sweep (IID + bursty), informational + loose bounds, kept out of normal CI.
