⭐ What's New

🔐 Authentication Bypass Tester Module

Professional authentication security testing with 5 attack categories:

Core Capabilities:

1. Default Credentials Testing

• 20 common username/password combinations
• Includes: admin:admin, root:root, administrator, guest, etc.
• Automatic success detection
• CRITICAL severity classification

2. Session Fixation

• Tests pre-set session ID acceptance
• Session regeneration validation
• HIGH severity vulnerabilities

3. Cookie Manipulation

• 8 bypass techniques:
  • admin=true, isAdmin=1
  • role=admin, user_type=admin
  • authenticated=true, logged_in=1
  • auth=1, is_authenticated=true
• HIGH severity classification

4. JWT Token Manipulation

• None Algorithm Attack (signature removal)
• Role manipulation (elevate to admin)
• User ID tampering
• CRITICAL severity vulnerabilities

5. Password Reset Testing

• Token reusability
• Predictable token detection
• Empty token bypass
• CRITICAL severity

Key Features:

• 🎯 30+ attack techniques across 5 categories
• 🔍 Selective test execution
• 📊 Severity-based classification
