CVE-2024-23113 FortiOS Test Environment

A Docker-based test environment for validating CVE-2024-23113 Nuclei templates against simulated vulnerable FortiOS instances.

🔍 Overview

This environment simulates vulnerable FortiOS HTTP interfaces to test the detection capabilities of CVE-2024-23113 Nuclei templates. It provides realistic FortiOS responses including login pages, API endpoints, and proper version information.

🚀 Quick Start

Prerequisites

• Docker
• Docker Compose
• Nuclei (for testing)

Basic Setup

1. Clone and build:

git clone <this-repository>
cd cve-2024-23113-test-env
docker-compose up -d

2. Verify the environment:

curl http://localhost:8080/

3. Test with Nuclei:

# Test against vulnerable instance
nuclei -t CVE-2024-23113.yaml -u http://localhost:8080 -v

# Test with debug output
nuclei -t CVE-2024-23113.yaml -u http://localhost:8080 -debug

🎯 Available Environments

Default Environment

• Service: fortios-vulnerable
• Port: 8080
• Version: FortiOS v7.2.5 (vulnerable)
• URL: http://localhost:8080

Additional Test Environments

# Start patched version for comparison
docker-compose --profile patched up -d

# Start multiple vulnerable versions
docker-compose --profile multiple up -d

Available Profiles:

• Default: FortiOS v7.2.5 (vulnerable) - Port 8080
• Patched: FortiOS v7.2.7 (patched) - Port 8081
• Multiple:
  • FortiOS v7.4.1 (vulnerable) - Port 8082
  • FortiOS v7.0.10 (vulnerable) - Port 8083

🔧 Configuration

Environment Variables

Custom Version

# Run specific version
docker run -p 8080:8080 -e FORTIOS_VERSION=7.4.2 cve-2024-23113-test

📡 API Endpoints

The simulated FortiOS provides these endpoints:

Example API Response

{
  "version": "v7.2.5",
  "hostname": "TEST-FORTIGATE",
  "serial": "FGTVM1234567890",
  "build": 1396,
  "model": "FortiGate-VM64"
}

🧪 Testing Scenarios

Vulnerable Versions Detection

# Test vulnerable versions
nuclei -t CVE-2024-23113.yaml -u http://localhost:8080     # v7.2.5
nuclei -t CVE-2024-23113.yaml -u http://localhost:8082     # v7.4.1  
nuclei -t CVE-2024-23113.yaml -u http://localhost:8083     # v7.0.10

Patched Version Validation

# Test patched version (should not detect)
nuclei -t CVE-2024-23113.yaml -u http://localhost:8081     # v7.2.7

Batch Testing

# Test all instances
echo -e "http://localhost:8080\nhttp://localhost:8081\nhttp://localhost:8082\nhttp://localhost:8083" | nuclei -t CVE-2024-23113.yaml -l /dev/stdin

🔍 Manual Testing

Check Service Response

# Basic connectivity
curl -v http://localhost:8080/

# API endpoint
curl -s http://localhost:8080/api/v2/monitor/system/status | jq .

# Check headers
curl -I http://localhost:8080/

Expected Vulnerable Indicators

• HTML: Contains FortiOS v7.2.5
• Server Header: FortiGate-HTTP/v7.2.5
• API Response: "version": "v7.2.5"

🐛 Troubleshooting

Common Issues

Port Already in Use

# Check what's using the port
netstat -tlnp | grep 8080

# Use different port
docker-compose up -d --scale fortios-vulnerable=0
docker run -p 8090:8080 cve-2024-23113-test

Container Won't Start

# Check logs
docker-compose logs fortios-vulnerable

# Rebuild image
docker-compose build --no-cache

Health Check Failing

# Check container health
docker ps
docker exec cve-2024-23113-vulnerable curl -f http://localhost:8080/

Debugging

# View real-time logs
docker-compose logs -f

# Interactive shell
docker exec -it cve-2024-23113-vulnerable /bin/bash

# Test from inside container
docker exec cve-2024-23113-vulnerable curl localhost:8080
