+# CodePress CMS Penetration Test Suite
+
+## 🔒 Overview
+Comprehensive security testing script voor CodePress CMS. Test 10 kritieke attack vectors met 40+ individuele tests.
+
+## ⚠️ WAARSCHUWING
+**Gebruik dit script ALLEEN op systemen waar je toestemming voor hebt!**
+Ongeautoriseerde penetration testing is illegaal.
+
+## 📋 Test Categorieën
+
+### 1. **XSS (Cross-Site Scripting)**
+- Page parameter injection
+- Search parameter injection  
+- Language parameter injection
+- HTML entity encoding
+- SVG/IMG tag injection
+
+### 2. **Path Traversal**
+- Basic `../` attacks
+- URL encoding bypass
+- Double encoding
+- Backslash variants
+- Mixed separators
+- Config file access
+
+### 3. **PHP Code Injection**
+- PHP wrapper attacks
+- Data URI execution
+- Expect wrapper exploitation
+
+### 4. **Null Byte Injection**
+- Null byte in parameters
+- Extension bypass attempts
+
+### 5. **Command Injection**
+- Shell command injection in search
+- Backtick command execution
+- Pipe operator injection
+
+### 6. **Template Injection**
+- Mustache SSTI (Server-Side Template Injection)
+- Config disclosure via templates
+
+### 7. **HTTP Header Injection**
+- CRLF injection
+- Header manipulation
+
+### 8. **Information Disclosure**
+- PHP version leakage
+- Directory listing
+- Config file exposure
+- Dependency disclosure
+
+### 9. **Security Headers**
+- X-Frame-Options
+- Content-Security-Policy
+- X-Content-Type-Options
+- Referrer-Policy
+
+### 10. **Denial of Service (DoS)**
+- Large parameter attacks
+- Resource exhaustion
+
+## 🚀 Gebruik
+
+### Vereisten
+- bash
+- curl
+- python3 (voor lange strings)
+- Lopende CodePress CMS instance
+
+### Uitvoeren
+
+```bash
+# Start de server
+php -S localhost:8080 -t public
+
+# In een andere terminal
+./pentest.sh
+```
+
+### Output
+
+Het script genereert:
+1. **Console output** - Real-time test resultaten met kleuren
+2. **pentest_results.txt** - Gedetailleerd rapport
+
+### Resultaat Codes
+
+- 🟢 **[SAFE]** - Aanval geblokkeerd ✅
+- 🔴 **[VULNERABLE]** - Kwetsbaarheid gevonden ❌  
+- 🟡 **[POTENTIAL]** - Mogelijk kwetsbaar ⚠️
+- 🟡 **[UNKNOWN]** - Onverwachte response ⚠️
+
+## 📊 Voorbeeld Output
+
+```
+========================================
+1. XSS VULNERABILITY TESTS
+========================================
+
+Testing: XSS in page parameter...[SAFE] ✅
+Testing: XSS in search parameter...[SAFE] ✅
+Testing: XSS in lang parameter...[SAFE] ✅
+
+========================================
+PENETRATION TEST SUMMARY
+========================================
+
+Total tests: 40
+Vulnerabilities found: 0
+Safe tests: 40
+
+✅ All tests passed! System appears secure.
+```
+
+## 🛡️ Verwachte Resultaten
+
+CodePress CMS zou **ALLE** tests moeten doorstaan:
+
+| Categorie | Verwacht Resultaat |
+|-----------|-------------------|
+| XSS | ✅ Blocked |
+| Path Traversal | ✅ Blocked |
+| PHP Injection | ✅ Blocked |
+| Command Injection | ✅ Blocked |
+| Template Injection | ✅ Blocked |
+| Security Headers | ✅ Present |
+| Info Disclosure | ✅ Hidden |
+
+## 🔧 Aanpassen
+
+### Target wijzigen
+```bash
+# Bewerk bovenaan pentest.sh
+TARGET="http://your-domain.com"
+```
+
+### Tests toevoegen
+```bash
+test_vulnerability \
+    "Jouw test naam" \
+    "$TARGET/?param=payload" \
+    "search_pattern" \
+    "true"  # true = vulnerable if found
+```
+
+## 📚 OWASP Top 10 Coverage
+
+- ✅ A01:2021 - Broken Access Control
+- ✅ A02:2021 - Cryptographic Failures  
+- ✅ A03:2021 - Injection
+- ✅ A05:2021 - Security Misconfiguration
+- ✅ A06:2021 - Vulnerable Components
+- ✅ A07:2021 - Authentication Failures
+
+## 🐛 Gevonden Vulnerability?
+
+1. Stop met testen
+2. Documenteer de vulnerability in `pentest_results.txt`
+3. Fix de code
+4. Run de test opnieuw
+5. Commit NIET de vulnerability voor de fix klaar is

+
+## Security Controls Implemented
+
+### ✅ Input Validation
+- All user inputs are validated and sanitized
+- Language parameter restricted to whitelist (`nl`, `en`)
+- Path parameters stripped of traversal sequences
+- HTML special characters escaped
+
+### ✅ Output Encoding
+- `htmlspecialchars()` used consistently
+- ENT_QUOTES flag prevents attribute injection
+- UTF-8 encoding enforced
+
+### ✅ Access Control
+- Direct content directory access blocked
+- Config files protected via router
+- PHP execution in content directory restricted
+- Vendor directory not publicly accessible
+
+### ✅ Security Headers
+- Comprehensive CSP policy
+- Clickjacking protection (X-Frame-Options)
+- MIME-sniffing prevention
+- XSS filtering enabled
+- Referrer policy configured
+
+### ✅ Error Handling
+- Generic error messages (no stack traces)
+- 404 pages don't reveal file structure
+- 403 pages use generic "Access denied" message
+
+### ✅ File Security
+- `.htaccess` blocks PHP execution in content
+- Router provides additional protection layer
+- Dangerous PHP functions detected in content files
+
+---
+
+## Recommendations
+
+### 🟢 Strengths
+1. **Multi-layered security** - Defense in depth approach
+2. **Consistent input validation** - All entry points validated
+3. **Proper output encoding** - XSS vulnerabilities eliminated
+4. **Security headers** - Comprehensive header implementation
+5. **File-based CMS** - No SQL injection risk
+
+### 🟡 Areas for Improvement
+1. **Rate limiting** - Consider adding rate limiting for DoS protection
+2. **CSRF tokens** - Add CSRF protection for future form implementations
+3. **Content Security Policy** - Consider stricter CSP (remove 'unsafe-inline')
+4. **Logging** - Implement security event logging
+5. **PHP execution** - Consider complete PHP execution block in content (currently detects but still executes safe code)
+
+### 🔵 Future Enhancements
+1. **WAF integration** - Consider Web Application Firewall
+2. **Intrusion detection** - Monitor for attack patterns
+3. **Regular updates** - Automated dependency updates
+4. **Security scanning** - Regular automated scans
+5. **Penetration testing** - Annual professional pentests
