# Development Environment Setup
This document describes how to set up a development environment for Yggdrasil using Docker and VS Code Dev Containers.
## Prerequisites
- Docker installed and running
- VS Code with the "Dev Containers" extension installed
- Git configured with your user information
## Option 1: VS Code Dev Containers (Recommended)
1. Open this project in VS Code
2. When prompted, click "Reopen in Container" or:
- Press `Ctrl+Shift+P` (or `Cmd+Shift+P` on macOS)
- Type "Dev Containers: Reopen in Container"
- Select the option
VS Code will automatically build the development container and set up the environment with:
- Go 1.23 with all necessary tools
- Language server (gopls)
- Linting (golangci-lint)
- Debugging support (delve)
- Git integration
- Zsh shell with Oh My Zsh
## Option 2: Manual Docker Container
If you prefer to use Docker directly:
### Using Makefile commands:
```bash
# Build and run the development container
make -f Makefile dev
# Or build and run separately
make -f Makefile dev-build
make -f Makefile dev-run
# Get shell access to running container
make -f Makefile dev-shell
# Stop the container
make -f Makefile dev-stop
# Clean up
make -f Makefile dev-clean
```
### Using Docker directly:
```bash
# Build the development image
docker build -f Dockerfile -t yggdrasil-dev .
# Run the container
docker run -it --rm \
--name yggdrasil-dev \
-v $(pwd):/workspace \
-v ~/.gitconfig:/home/vscode/.gitconfig:ro \
-p 9000:9000 \
-p 9001:9001 \
-p 9002:9002 \
-p 9003:9003 \
--privileged \
--cap-add=NET_ADMIN \
--device=/dev/net/tun \
yggdrasil-dev
```
## Development Features
The development environment includes:
- **Go Tools**: gopls, delve debugger, goimports, golangci-lint, staticcheck
- **Editor Support**: Syntax highlighting, auto-completion, debugging
- **Testing**: Go test runner and coverage tools
- **Networking**: Privileged access for network interface testing
- **Port Forwarding**: Ports 9000-9003 exposed for Yggdrasil services
## Building and Testing
Inside the container:
```bash
# Build the project
./build
# Run tests
go test ./...
# Generate configuration
./yggdrasil -genconf > yggdrasil.conf
# Run with configuration
./yggdrasil -useconf yggdrasil.conf
```
## Tips
1. Your local Git configuration is mounted into the container
2. The workspace directory (`/workspace`) is mapped to your local project directory
3. All changes made to source files are persistent on your host machine
4. The container runs as a non-root user (`vscode`) for security
5. Network capabilities are enabled for testing network-related features
## Troubleshooting
- If the container fails to start, ensure Docker has enough resources allocated
- For network-related issues, verify that the container has the necessary privileges
- If Go tools are missing, rebuild the container: `make -f Makefile dev-clean dev-build`

# Security Improvements in Config Package
## Path Traversal Prevention
This package has been updated to prevent path traversal attacks by implementing the following security measures:
### 1. Path Validation Function
The `validateConfigPath()` function performs comprehensive validation of file paths:
- **Path Cleaning**: Uses `filepath.Clean()` to resolve `.` and `..` components
- **Absolute Path Resolution**: Converts all paths to absolute paths to prevent relative path issues
- **Traversal Pattern Detection**: Explicitly checks for `..` and `//` patterns
- **Control Character Filtering**: Prevents paths containing null bytes or control characters
- **File Extension Validation**: Restricts file extensions to known configuration formats
### 2. Secure File Operations
All file operations now use validated paths:
- **Config File Reading/Writing**: All `os.ReadFile()` and `os.WriteFile()` operations use validated paths
- **Directory Creation**: Directory paths are cleaned before `os.MkdirAll()` operations
- **Private Key Loading**: Private key file paths are validated in `postprocessConfig()`
### 3. Defense in Depth
Multiple layers of protection:
- **Input Validation**: All user-provided paths are validated before use
- **Path Canonicalization**: Paths are converted to canonical form
- **Extension Whitelisting**: Only allowed file extensions are permitted
- **Error Handling**: Invalid paths return descriptive errors without exposing system details
## Additional Security Measures
### 4. System Directory Protection
Restricted access to sensitive system directories:
- Blocks access to `/etc/` (except `/etc/yggdrasil/`)
- Blocks access to `/root/`, `/var/` (except `/var/lib/yggdrasil/`)
- Blocks access to `/sys/`, `/proc/`, `/dev/`
### 5. Path Depth Limiting
Maximum path depth of 10 levels to prevent deeply nested attacks.
## Allowed File Extensions
The following file extensions are permitted for configuration files:
- `.json` - JSON configuration files
- `.hjson` - Human JSON configuration files
- `.conf` - Generic configuration files
- `.config` - Configuration files
- `.yml` - YAML configuration files
- `.yaml` - YAML configuration files
- (no extension) - Files without extensions
## Migration Notes
Existing code using this package should continue to work without changes. Invalid paths that were previously accepted may now be rejected with appropriate error messages.
All file operations now include validation comments in the source code to indicate when paths have been pre-validated.
## Testing
To verify path validation is working correctly:
```go
// Valid paths
validPath, err := validateConfigPath("/etc/yggdrasil/config.json")
// Invalid paths (should return errors)
_, err = validateConfigPath("../../../etc/passwd")
_, err = validateConfigPath("/config/../../../etc/shadow")
```

# WebUI Module
This module provides a web interface for managing Yggdrasil node through a browser.
## Features
- ✅ HTTP web server with static files
- ✅ Health check endpoint (`/health`)
- ✅ Development and production build modes
- ✅ Custom session-based authentication
- ✅ Beautiful login page (password-only)
- ✅ **Brute force protection** with IP blocking
- ✅ Session management with automatic cleanup
- ✅ IPv4 and IPv6 support
- ✅ Path traversal attack protection
## Configuration
In the Yggdrasil configuration file:
```json
{
"WebUI": {
"Enable": true,
"Port": 9000,
"Host": "",
"Password": "your_secure_password"
}
}
```
### Configuration parameters:
- **`Enable`** - enable/disable WebUI
- **`Port`** - port for web interface (default 9000)
- **`Host`** - IP address to bind to (empty means all interfaces)
- **`Password`** - password for accessing the web interface (optional, if empty no authentication required)
## Usage
### Without password authentication
```go
server := webui.Server("127.0.0.1:9000", "", logger)
```
### With password authentication
```go
server := webui.Server("127.0.0.1:9000", "your_password", logger)
```
### Starting the server
```go
go func() {
if err := server.Start(); err != nil {
logger.Errorf("WebUI server error: %v", err)
}
}()
// To stop
server.Stop()
```
## Endpoints
- **`/`** - main page (index.html) - requires authentication if password is set
- **`/login.html`** - custom login page (only password required)
- **`/auth/login`** - POST endpoint for authentication
- **`/auth/logout`** - logout endpoint (clears session)
- **`/health`** - health check (returns "OK") - no authentication required
- **`/static/*`** - static files (CSS, JS, images) - requires authentication if password is set
## Build modes
### Development mode (`-tags debug`)
- Files loaded from disk from `src/webui/static/`
- File changes available without rebuild
### Production mode (default)
- Files embedded in binary
- Faster loading, smaller deployment size
## Security
- Path traversal attack protection
- Configured HTTP timeouts
- Header size limits
- File MIME type validation
- Custom session-based authentication (password protection)
- HttpOnly and Secure cookies
- Session expiration (24 hours)
- **Brute force protection**: IP blocking after 3 failed attempts
- **Temporary lockout**: 1-minute timeout for blocked IPs
- Automatic cleanup of expired blocks and sessions
- Real IP detection (supports X-Forwarded-For, X-Real-IP headers)
- Health check endpoint always accessible without authentication
## Testing
The module includes a comprehensive test suite:
```bash
cd src/webui
go test -v
```
Tests cover:
- Server creation and management
- HTTP endpoints
- Static files (dev and prod modes)
- Error handling
- Configuration
- Yggdrasil IPv6 binding

// Example Yggdrasil configuration with WebUI password authentication
"PrivateKey": "your_private_key_here",
"PublicKey": "your_public_key_here",
// ... other Yggdrasil configuration options ...
// Web interface configuration
"WebUI": {
"Enable": true,
"Port": 9000,
"Host": "127.0.0.1", // Bind only to localhost for security
"Password": "your_secure_password_here" // Set a strong password
}
}
// Usage examples:
//
// 1. Enable WebUI with password protection:
// Set "Password" to a strong password
// Users will see a custom login page asking only for password
//
// 2. Disable password protection:
// Set "Password" to "" (empty string)
// WebUI will be accessible without authentication
//
// 3. Disable WebUI entirely:
// Set "Enable" to false
//
// Authentication features:
// - Custom login page (no username required, only password)
// - Session-based authentication with secure cookies
// - 24-hour session expiration
// - Automatic session cleanup
// - Brute force protection (3 failed attempts = 1 minute block)
// - IP-based blocking with automatic cleanup
//
// Security recommendations:
// - Use a strong, unique password (12+ characters)
// - Bind to localhost (127.0.0.1) unless you need remote access
// - Consider using HTTPS reverse proxy for production deployments
// - Sessions are stored in memory and lost on server restart
// - Failed login attempts are tracked per IP address
// - If behind a reverse proxy, ensure X-Forwarded-For headers are set correctly
