## Overview
**Role: Web Application Security Specialist** — Your job is to systematically test every endpoint in the recon deliverable for web application vulnerabilities. Stay in your lane: you test and discover, you do NOT verify findings or write final reports. Operational methodology for web application penetration testing. Covers the full pentest lifecycle from reconnaissance through post-exploitation. Every phase maps to specific tools and techniques with exact commands.
## Pipeline Position
> **Position:** Phase 3 (Testing) — after `recon-and-enumeration`, before `vulnerability-verification`
> **Expected Input:** Recon deliverable containing: endpoint inventory, technology stack, authentication mechanisms, attack surface map
> **Your Output:** Raw findings with evidence, classified by vulnerability type (injection, XSS, SSRF, auth, authz, etc.)
> **Consumed By:** `vulnerability-verification` (confirms/dismisses each finding), `writing-security-reports` (documents findings)
> **Critical:** Your findings go to verification — do NOT self-verify. That's the next skill's job. Focus on thorough discovery.
This skill assumes you have authorized access to the target. All commands target the application in scope.
**REQUIRED SUB-SKILL:** Use superhackers:recon-and-enumeration for pre-engagement target discovery.
## When to Use
- Target is a web application (HTTP/HTTPS)
- Scope includes webapp vulnerability assessment
- User requests OWASP Top 10 testing
- Testing for specific webapp vulns (XSS, SQLi, SSRF, etc.)
- Web server security assessment needed
- User provides a URL or domain to test
- Post-authentication testing of webapp features
- File upload, form submission, or input validation testing
## Analysis Methodology: Taint-First
Before running automated scanners or spraying generic payloads, trace the data flow for each endpoint:
1. **Identify sources:** All user-controlled inputs (query params, POST body, headers, cookies, file uploads, WebSocket messages, path segments)
2. **Trace to sinks:** Where does each input end up? (SQL query, HTML template, shell command, file path, HTTP request, email body, log entry)
3. **Check defenses at each sink:** Is there sanitization, encoding, parameterization, or WAF protection? Is it correct for the output context?
4. **Find mismatches:** Input sanitized for HTML context but used in SQL? Parameterized for values but not for identifiers? Encoded for URL but inserted into JavaScript?
5. **Target payloads:** Generate payloads specific to the identified mismatch — don't spray generic XSS/SQLi payloads at every input
This approach yields higher-confidence findings and fewer false positives than scan-first testing. Automated scanners (nikto, nuclei, ffuf) are complementary tools for coverage, not replacements for taint analysis.
## Core Pattern
```
1. RECON → Map attack surface (endpoints, params, tech stack)
2. SCAN → Automated vulnerability scanning
3. ENUMERATE → Discover hidden content, params, functionality
4. EXPLOIT → Test and confirm vulnerabilities
5. POST-EXPLOIT → Assess impact, pivot, escalate
6. REPORT → Document findings with evidence
```
### Execution Discipline
- **Persist**: Continue working through ALL steps of the Core Pattern until completion criteria are met. Do NOT stop after a single tool run or partial result.
- **Scope**: Work ONLY within this skill's methodology. Do NOT jump to another phase (e.g., don't start writing the report while still testing).
- **Negative Results**: If thorough testing reveals no vulnerabilities, that IS a valid result. Document what was tested and report "no findings" — do NOT invent issues.
- **Retry Limit**: Max 3 attempts per test. If blocked, classify the failure (see Failure Recovery Protocol) and proceed.

## Implementation
### Phase 1: Reconnaissance
#### 1.1 Port and Service Discovery
> **Use the rustscan → nmap two-phase pattern. Run rustscan for fast port discovery, then feed confirmed open ports to nmap for service detection. Never run nmap full-range scans directly — they timeout and produce empty output.**
```bash
# Phase A: Fast port discovery with rustscan
rustscan -a TARGET_IP --ulimit 5000 -b 1000 -- --open -oG webapp_rustscan_ports.gnmap
# Extract open port list
OPEN_PORTS=$(rg -o '[0-9]+/open' webapp_rustscan_ports.gnmap | cut -d/ -f1 | sort -n | paste -sd',')
echo "Open ports: $OPEN_PORTS" | tee open_ports.txt
# Phase B: Service detection on confirmed open ports only
nmap -sV -sC -p "$OPEN_PORTS" TARGET_IP -oA webapp_nmap
# Quick top ports with OS detection — confirmed ports only
nmap -sV -O -p "$OPEN_PORTS" -oA webapp_quick_scan TARGET_IP
# HTTP-specific NSE scripts — on confirmed web ports only
nmap -p 80,443,8080,8443 --script=http-title,http-headers,http-methods,http-robots.txt TARGET_IP
```
#### 1.2 Technology Fingerprinting
```bash
# Probe live hosts and extract tech stack
echo "https://TARGET" | httpx -tech-detect -status-code -title -web-server -content-length -follow-redirects
# Check multiple ports for HTTP services
echo "TARGET" | httpx -ports 80,443,8080,8443,3000,5000,8000 -title -status-code -tech-detect
# Extract headers for tech identification
curl -sI https://TARGET | rg -i 'server|x-powered|x-aspnet|x-generator|set-cookie'
```
#### 1.3 SSL/TLS Assessment
```bash
# ─── Cross-platform timeout helper ────────────────────────────────────────
# For macOS compatibility, use: bash $SUPERHACKERS_ROOT/scripts/timeout-helper.sh
# ────────────────────────────────────────────────────────────────────────────────
# Run only if port 443 confirmed open by rustscan
# For long-running commands, use: bash $SUPERHACKERS_ROOT/scripts/timeout-helper.sh 60 nmap --script ssl-enum-ciphers,ssl-cert,ssl-known-key -p 443 TARGET
```
#### 1.4 SPA and JavaScript Application Discovery
> **Modern SPA Context:** Single Page Applications (React, Vue, Angular, Svelte) have different attack surfaces than traditional multi-page apps. Client-side routing means traditional directory brute forcing often fails — API endpoints and routes are hidden in JavaScript bundles.
**SPA Detection:**
```bash
# Check if it's an SPA (single page application)
# Indicators: #/ routes, .js bundle files, client-side routing
curl -s https://TARGET | rg -o "href=\"#/[^\"]*\"|router|react|vue|angular"
# Detect JavaScript frameworks
curl -s https://TARGET | rg -i "react|vue|angular|svelte|ember|backbone|knockout"
# Check for service workers (PWA indicator)
curl -s https://TARGET/service-worker.js 2>/dev/null | head -20
# Find JavaScript bundle files
curl -s https://TARGET | rg -o 'src="[^"]*\.js"' | cut -d'"' -f2 | sort -u
curl -s https://TARGET | rg -o 'src="[^"]*\.jsx"' | cut -d'"' -f2 | sort -u
curl -s https://TARGET | rg -o 'src="[^"]*\.ts"' | cut -d'"' -f2 | sort -u
```
**JavaScript Bundle Analysis:**
```bash
# Download and analyze JavaScript bundles for:
# - Hidden API endpoints
# - Secret keys/tokens
# - Internal routes
# - Authentication bypasses
# - Hardcoded credentials
# Extract all JS file URLs
curl -s https://TARGET | rg -o 'src="[^"]*\.js"' | cut -d'"' -f2 | while read js; do
echo "=== $js ==="
curl -s "https://TARGET/$js" | head -100
done
# Search for API endpoints in bundles
curl -s https://TARGET/main.js | rg -o '"/api/[^"]*"' | sort -u
curl -s https://TARGET/app.js | rg -o '"/v[0-9]+/[^"]*"' | sort -u
# Extract potential secrets from bundles
curl -s https://TARGET/main.js | rg -i 'apikey|api_key|secret|token|password|aws_access|private_key|stripe'
# Find internal routes in React/Vue router configs
curl -s https://TARGET/main.js | rg -o 'path:"[^"]*"' | cut -d'"' -f2
curl -s https://TARGET/app.js | rg -o 'path: *`[^`]*`' | cut -d'`' -f2
# Map component names to discover hidden features
curl -s https://TARGET/main.js | rg -o '[A-Z][a-zA-Z]+Component|[A-Z][a-zA-Z]+Page' | sort -u
```
**Client-Side State Testing:**
```bash
# Test localStorage and sessionStorage manipulation
# Check for sensitive data stored client-side
# API keys, session tokens, user data, feature flags
# Use browser DevTools or Burp Suite to inspect:
# - localStorage for data persistence
# - sessionStorage for session data
# - IndexedDB for larger datasets
# - Cookies (especially HttpOnly, Secure, SameSite flags)
# Common localStorage keys to check:
# - authToken, accessToken, sessionToken
# - user, userProfile, userInfo
# - featureFlags, config, settings
# - apiKeys, credentials
# Test state manipulation attacks:
# 1. Copy localStorage from admin account
# 2. Replace localStorage in regular user session
# 3. Reload page to check for privilege escalation
# 4. Modify feature flags to access premium features
```
**DOM-Based XSS Testing for SPAs:**
```bash
# DOM XSS sinks common in SPAs:
# - location.hash (/#payload)
# - location.search (?param=value)
# - window.name
# - postMessage() handlers
# - innerHTML, outerHTML assignments
# - jQuery() / $.html() calls
# Test URL hash-based XSS (common in SPAs)
curl -s "https://TARGET/#
"
# Test search param pollution
curl -s "https://TARGET/?search="
# Extract and test dangerous JavaScript sinks from bundles
curl -s https://TARGET/main.js | rg -i '\.innerHTML|\.outerHTML|document\.write|dangerouslySetInnerHTML'
```
**Client-Side Route Discovery:**
```bash
# SPA routes often defined in JavaScript, not discoverable by dirbusting
# Extract routes from bundles
# React Router pattern
curl -s https://TARGET/main.js | rg -o 'path:"[^"]*"' | sort -u
# Vue Router pattern
curl -s https://TARGET/app.js | rg -o 'path: *`[^`]*`' | sort -u
# Angular routes
curl -s https://TARGET/main.js | rg -o 'path: ?[^,]*' | sort -u
# Test discovered routes
for route in admin dashboard settings profile api; do
code=$(curl -s -o /dev/null -w "%{http_code}" "https://TARGET/#/$route")
echo "Route /$route: HTTP $code"
done
```
**SPA-Specific Attack Vectors:**
```bash
# 1. API Versioning — Old versions often have weaker validation
curl -s https://TARGET | rg -o '"/api/v[0-9]+/[^"]*"'
# 2. Direct API calls bypass UI restrictions
# UI may disable buttons, but API still accepts requests
curl -X POST https://TARGET/api/admin/deleteUser -H "Authorization: Bearer USER_TOKEN"
# 3. Client-side validation bypass
# Form validation happens in browser — API may not validate
curl -X POST https://TARGET/api/users \
-H "Content-Type: application/json" \
-d '{"email":"invalid","role":"admin"}' \
-H "Authorization: Bearer REGULAR_USER_TOKEN"
# 4. WebSocket endpoint discovery
curl -s https://TARGET/main.js | rg -o 'wss?://[^"]*' | sort -u
# 5. GraphQL introspection (if using GraphQL)
curl -s -X POST https://TARGET/graphql \
-H "Content-Type: application/json" \
-d '{"query":"{__schema{types{name}}}"}'
```
**Bundle Analysis Tools:**
```bash
# Use specialized tools for JavaScript bundle analysis
# JSLinkScan - extract links from JavaScript
# https://github.com0compenhagen/jslinkscan
# Rule-based search for secrets in bundles
curl -s https://TARGET/main.js | rg -iE "['\"]?[a-zA-Z0-9_\-]*(api|secret|token|key|pwd|password|auth)['\"]?\s*[:=]\s*['\"]?[A-Za-z0-9_\-]+"
# Extract base64 encoded data (may contain secrets)
curl -s https://TARGET/main.js | rg -o '"[A-Za-z0-9+/]{20,}={0,2}"' | while read b64; do
echo "$b64" | base64 -d 2>/dev/null | rg -a . && echo "--- Decoded from: $b64"
done
```
> **Critical:** In SPAs, the real API surface is hidden in JavaScript. Always download and analyze bundles before concluding that "no endpoints exist." A traditional nmap/ffuf approach will miss the majority of the attack surface in modern applications.
### Phase 2: Scanning
#### 2.1 Web Server Scanning
```bash
# Nikto full scan
nikto -h https://TARGET -output nikto_results.txt -Format txt
# Nikto with authentication
nikto -h https://TARGET -id admin:password -output nikto_auth.txt
# Nikto targeting specific tuning
# 1=Files, 2=Misconfig, 3=Info, 4=XSS, 5=RFI, 9=SQLi
nikto -h https://TARGET -Tuning 1234 -output nikto_tuned.txt
```
#### 1.5 Browser Automation for SPA Testing (Playwright/Puppeteer with Stealth)
> **Critical:** Headless browsers are easily detected by websites. Always use stealth configurations to avoid bot detection, WAF blocking, and false negatives during SPA security testing.
**Playwright Stealth Setup:**
```bash
# Install Playwright with stealth plugin
npm init -y
npm install playwright playwright-extra
npm install playwright-extra-plugin-stealth
# Or use Python
pip install playwright-stealth playwright
```
**Stealth Playwright Configuration (JavaScript/Node.js):**
```javascript
const { chromium } = require('playwright-extra');
const stealth = require('puppeteer-extra-plugin-stealth');
// Apply stealth plugin
chromium.use(stealth());
(async () => {
// Launch with realistic browser configuration
const browser = await chromium.launch({
headless: true, // or false for debugging (more realistic)
args: [
'--disable-blink-features=AutomationControlled',
'--disable-dev-shm-usage',
'--no-sandbox',
'--disable-setuid-sandbox',
'--disable-web-security',
'--disable-features=IsolateOrigins,site-per-process',
],
});
const context = await browser.newContext({
userAgent: 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36',
viewport: { width: 1920, height: 1080 },
locale: 'en-US',
timezoneId: 'America/New_York',
permissions: ['geolocation', 'notifications'],
colorScheme: 'light',
});
const page = await context.newPage();
// Add realistic browser headers
await page.setExtraHTTPHeaders({
'Accept-Language': 'en-US,en;q=0.9',
'Accept-Encoding': 'gzip, deflate, br',
'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8',
'DNT': '1',
'Connection': 'keep-alive',
'Upgrade-Insecure-Requests': '1',
'Sec-Fetch-Dest': 'document',
'Sec-Fetch-Mode': 'navigate',
'Sec-Fetch-Site': 'none',
'Sec-Fetch-User': '?1',
'Cache-Control': 'max-age=0',
});
// Navigate to target SPA
await page.goto('https://TARGET', { waitUntil: 'networkidle' });
// Wait for SPA to fully load
await page.waitForLoadState('networkidle');
// Continue with security testing...
})();
```
**Stealth Playwright Configuration (Python):**
```python
from playwright.sync_api import sync_playwright
import random
import time
def random_delay(min_ms=100, max_ms=500):
delay = random.randint(min_ms, max_ms) / 1000
time.sleep(delay)
with sync_playwright() as p:
# Launch with stealth configuration
browser = p.chromium.launch(
headless=True,
args=[
'--disable-blink-features=AutomationControlled',
'--disable-dev-shm-usage',
'--no-sandbox',
'--disable-setuid-sandbox',
],
)
context = browser.new_context(
user_agent='Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36',
viewport={'width': 1920, 'height': 1080},
locale='en-US',
timezone_id='America/New_York',
)
# Add realistic headers
context.set_extra_http_headers({
'Accept-Language': 'en-US,en;q=0.9',
'Accept-Encoding': 'gzip, deflate, br',
'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
'DNT': '1',
'Connection': 'keep-alive',
'Upgrade-Insecure-Requests': '1',
'Sec-Fetch-Dest': 'document',
'Sec-Fetch-Mode': 'navigate',
'Sec-Fetch-Site': 'none',
'Sec-Fetch-User': '?1',
})
page = context.new_page()
# Navigate with human-like delays
random_delay(500, 1500) # Wait before navigation
page.goto('https://TARGET', wait_until='networkidle')
random_delay(1000, 2000) # Wait after page load
# Simulate human behavior
page.mouse.move(100, 100)
random_delay(100, 300)
page.mouse.move(200, 150)
random_delay(100, 300)
# Continue with security testing...
```
**DOM XSS Testing with Playwright (Stealth):**
```javascript
// Test DOM XSS in SPA with stealth Playwright
await page.goto('https://TARGET/#');
// Wait for SPA to process the hash
await page.waitForTimeout(2000);
// Check if XSS executed (check for alert dialog)
page.on('dialog', async dialog => {
console.log('XSS Detected:', dialog.message());
await dialog.accept();
});
// Alternative: Execute in page context and check for script execution
const xssExecuted = await page.evaluate(() => {
// Check if payload was injected into DOM
const img = document.querySelector('img[src*="x onerror"]');
return img !== null;
});
console.log('XSS Payload in DOM:', xssExecuted);
```
**JavaScript Bundle Extraction with Playwright:**
```javascript
// Extract all JavaScript files from SPA
const jsFiles = await page.evaluate(() => {
const scripts = Array.from(document.querySelectorAll('script[src]'));
return scripts.map(s => s.src);
});
console.log('JavaScript files found:', jsFiles);
// Download and analyze each bundle
for (const jsFile of jsFiles) {
const response = await page.goto(jsFile);
const content = await response.text();
// Extract API endpoints
const apiEndpoints = content.match(/"\/api\/[^"]*"/g) || [];
const uniqueEndpoints = [...new Set(apiEndpoints)];
console.log(`API endpoints from ${jsFile}:`, uniqueEndpoints);
// Extract secrets
const secrets = content.match(/(apikey|api_key|secret|token|password)["']?\s*[:=]\s*["']?[^"'\s]+/gi) || [];
console.log(`Potential secrets from ${jsFile}:`, secrets);
// Add delay between requests to avoid detection
await page.waitForTimeout(Math.random() * 1000 + 500);
}
```
**Client-Side State Testing with Playwright:**
```javascript
// Test localStorage/sessionStorage manipulation
await page.goto('https://TARGET/dashboard');
// Get current localStorage
const currentStorage = await page.evaluate(() => {
return {
...localStorage,
...sessionStorage,
};
});
console.log('Current storage:', currentStorage);
// Test privilege escalation via localStorage manipulation
await page.evaluate(() => {
localStorage.setItem('user_role', 'admin');
localStorage.setItem('isPremium', 'true');
localStorage.setItem('feature_all_access', 'enabled');
});
// Reload page to test if privileges changed
await page.reload();
await page.waitForTimeout(2000);
// Check if admin features are now accessible
const hasAdminAccess = await page.evaluate(() => {
return document.querySelector('[data-admin-only]') !== null;
});
console.log('Admin access gained:', hasAdminAccess);
```
**Route Discovery with Playwright:**
```javascript
// Discover client-side routes in SPA
const routes = await page.evaluate(() => {
// React Router
const reactRoutes = Array.from(document.querySelectorAll('[href*="#/"]'))
.map(el => el.getAttribute('href'));
// Vue Router
const vueRoutes = Array.from(document.querySelectorAll('a[href^="#/"]'))
.map(el => el.getAttribute('href'));
return [...reactRoutes, ...vueRoutes];
});
console.log('SPA routes found:', routes);
// Test each route for access control
for (const route of routes) {
await page.goto(`https://TARGET${route}`);
await page.waitForTimeout(1000);
const statusCode = await page.evaluate(() => {
// Check for error pages or redirects
const hasError = document.body.textContent.includes('404') ||
document.body.textContent.includes('Not Found');
return hasError ? '404' : '200';
});
console.log(`Route ${route}: ${statusCode}`);
}
```
**Human-Like Behavior Simulation:**
```javascript
// Add random mouse movements and delays to appear human
async function simulateHumanBehavior(page) {
// Random mouse movements
for (let i = 0; i < 5; i++) {
const x = Math.floor(Math.random() * 1000) + 100;
const y = Math.floor(Math.random() * 500) + 100;
await page.mouse.move(x, y);
await page.waitForTimeout(Math.random() * 300 + 100);
}
// Random scrolling
await page.evaluate(() => {
window.scrollBy(0, Math.random() * 500);
});
await page.waitForTimeout(Math.random() * 1000 + 500);
}
// Use before each navigation
await simulateHumanBehavior(page);
```
**Detection Indicators to Avoid:**
```javascript
// Check if your browser is being detected
const detectionChecks = await page.evaluate(() => {
return {
webdriver: navigator.webdriver,
chrome: window.chrome ? window.chrome.runtime : null,
permissions: navigator.permissions,
plugins: navigator.plugins.length,
languages: navigator.languages.length,
platform: navigator.platform,
hardwareConcurrency: navigator.hardwareConcurrency,
deviceMemory: navigator.deviceMemory,
};
});
console.log('Detection checks:', detectionChecks);
// If webdriver: true, you're detected as a bot
```
**Rate Limiting with Playwright:**
```javascript
// Add delays between actions to avoid rate limiting
async function safeAction(page, action) {
const delay = Math.random() * 2000 + 1000; // 1-3 seconds
await page.waitForTimeout(delay);
return await action();
}
// Use for each request
await safeAction(page, () => page.click('#submit-button'));
await safeAction(page, () => page.goto('https://TARGET/page'));
```
> **Critical:** Always test your Playwright stealth setup against bot detection services like:
> - https://arh.antoinevastel.com/bots/areyouheadless
> - https://bot.sannysoft.com/
>
> If detected as a bot, adjust your configuration before testing the target.
#### 2.2 Vulnerability Scanning with Nuclei
> **MANDATORY: Always specify `-o` output file, `-timeout` flag, and validate output with `validate-output.sh` after every nuclei run. A nuclei run with no output file is an unverifiable run — the result CANNOT be reported.**
```bash
# Full scan with all templates — ALWAYS specify output file and timeout

### Checkpoint: Mid-Testing Assessment
Before proceeding to advanced techniques, pause and verify:
1. **Am I testing the right thing?** Re-confirm the technology stack matches your attack approach
2. **Are my payloads reaching the target?** Verify with a canary request (unique string in parameter — check response/logs for it)
3. **Am I getting real responses?** Check for WAF/proxy interference (compare response to a known-good baseline)
4. **What have I found so far?** Inventory findings and their verification status
5. **What's my time budget?** Am I spending proportional time to remaining scope?
If any answer reveals a problem, reassess before continuing.
### Phase 3: Enumeration
#### 3.1 Directory and File Discovery
```bash
# Basic directory brute-force
ffuf -u https://TARGET/FUZZ -H "User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36" -w /usr/share/wordlists/dirb/common.txt -o ffuf_dirs.json
# With extensions
ffuf -u https://TARGET/FUZZ -w /usr/share/wordlists/dirb/common.txt -e .php,.asp,.aspx,.jsp,.html,.js,.txt,.bak,.old,.conf -o ffuf_files.json
# Filter by status code
ffuf -u https://TARGET/FUZZ -H "User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36" -w /usr/share/wordlists/dirb/big.txt -mc 200,301,302,403 -o ffuf_filtered.json
# Filter out specific response sizes (remove false positives)
ffuf -u https://TARGET/FUZZ -w /usr/share/wordlists/dirb/common.txt -fs 1234 -o ffuf_sized.json
# Recursive scanning
ffuf -u https://TARGET/FUZZ -w /usr/share/wordlists/dirb/common.txt -recursion -recursion-depth 3 -o ffuf_recursive.json
```
#### 3.2 Virtual Host Discovery
```bash
ffuf -u https://TARGET -H "User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36" -H "Host: FUZZ.TARGET" -w /usr/share/wordlists/dirb/common.txt -fs 0 -o ffuf_vhosts.json
```
#### 3.3 Parameter Discovery
```bash
# GET parameter fuzzing
ffuf -u "https://TARGET/page?FUZZ=test" -w /usr/share/wordlists/dirb/common.txt -fs 0 -o ffuf_params.json
# POST parameter fuzzing
ffuf -u https://TARGET/login -X POST -d "FUZZ=test" -H "Content-Type: application/x-www-form-urlencoded" -w /usr/share/wordlists/dirb/common.txt -fs 0 -o ffuf_post_params.json
```
#### 3.4 Subdomain Enumeration
```bash
ffuf -u https://FUZZ.TARGET.com -w /usr/share/wordlists/dirb/common.txt -fs 0 -o ffuf_subdomains.json
```
### Phase 4: Exploitation — OWASP Top 10 Testing
#### 4.1 A01 — Broken Access Control (IDOR/Auth Bypass)
**Checklist:**
- [ ] Test horizontal privilege escalation (access other users' data)
- [ ] Test vertical privilege escalation (access admin functions)
- [ ] Test direct object references (change IDs in URLs/params)
- [ ] Test forced browsing to admin pages
- [ ] Test HTTP method tampering (GET→PUT/DELETE)
- [ ] Test path traversal
**Manual Testing in BurpSuite:**
1. Capture authenticated request in Proxy → HTTP History
2. Send to Repeater (Ctrl+R)
3. Modify resource IDs: `/api/users/123` → `/api/users/124`
4. Modify role parameters: `role=user` → `role=admin`
5. Test method override: Add `X-HTTP-Method-Override: PUT` header
6. Test path traversal: `/api/users/../admin/config`
```bash
# Fuzz IDOR with sequential IDs
ffuf -u "https://TARGET/api/users/FUZZ" -w <(seq 1 1000) -H "Authorization: Bearer TOKEN" -mc 200 -o idor_results.json
# Test forced browsing to admin paths
ffuf -u https://TARGET/FUZZ -w /usr/share/wordlists/dirb/common.txt -H "Cookie: session=USER_SESSION" -mc 200 -o admin_paths.json
```
#### 4.2 A02 — Cryptographic Failures
**Checklist:**
- [ ] Check for HTTP (non-TLS) transmission of sensitive data
- [ ] Check for sensitive data in URLs (tokens, passwords)
- [ ] Check cookie flags (Secure, HttpOnly, SameSite)
- [ ] Check for weak hashing algorithms in stored data
- [ ] Check for hardcoded secrets in JavaScript files
```bash
# Find sensitive data in JS files
ffuf -u https://TARGET/FUZZ -w /usr/share/wordlists/dirb/common.txt -e .js,.map -mc 200 -o js_files.json
# Then ripgrep downloaded JS for secrets:
# apiKey, secret, password, token, aws_access, private_key
```
#### 4.3 A03 — Injection (SQLi, XSS, Command Injection)
##### SQL Injection
**Checklist:**
- [ ] Test all input fields with SQLi payloads
- [ ] Test URL parameters, headers, cookies
- [ ] Test both GET and POST parameters
- [ ] Test error-based, union-based, blind, time-based SQLi
- [ ] Test second-order SQLi
> **MANDATORY sqlmap rules:**
> 1. Always specify `--output-dir=./sqlmap_output` to save output for evidence
> 2. Always use `_to N CMD` (cross-platform timeout helper — define once per session, see below) to prevent silent hang
> 3. Validate output file exists and is non-empty after every run
> 4. A sqlmap run with no output file = an unverifiable test = NOT REPORTABLE
> 5. A timeout or empty output is a **TOOL FAILURE**, not a "not confirmed" result — re-run with reduced scope

```
##### Cross-Site Scripting (XSS)
**Checklist:**
- [ ] Test reflected XSS in all input fields and URL params
- [ ] Test stored XSS in user-generated content (comments, profiles)
- [ ] Test DOM-based XSS via URL fragments and JS sinks
- [ ] Test XSS in HTTP headers (User-Agent, Referer)
- [ ] Test XSS filter bypass techniques
- [ ] Check Content-Security-Policy header
**Manual XSS Testing in BurpSuite:**
1. Inject probe: `">` in all input fields
2. Check response for reflected input — note encoding/filtering
3. Try bypass payloads:
- `">`
- `">
