# Security Vulnerabilities Fix Status Report
|
|
|
|
**Date**: September 15, 2025
|
|
**Project**: MEV Bot (mev-beta)
|
|
**Status**: Critical security vulnerabilities addressed
|
|
|
|
## 🎯 Fixed Critical Security Issues
|
|
|
|
### ✅ 1. **Hardcoded Private Key Exposure**
|
|
**File**: `pkg/arbitrage/executor.go`
|
|
**Status**: **FIXED**
|
|
**Solution**: Implemented secure key retrieval from KeyManager using `GetActivePrivateKey()` method
|
|
**Verification**: Private key now comes from encrypted secure storage, not hardcoded values
|
|
|
|
### ✅ 2. **Default Encryption Key in Production**
|
|
**File**: `cmd/mev-bot/main.go`
|
|
**Status**: **FIXED**
|
|
**Solution**: Required `MEV_BOT_ENCRYPTION_KEY` environment variable with validation
|
|
**Verification**: Application fails to start without proper encryption key configuration
|
|
|
|
### ✅ 3. **Hardcoded Salt in Key Derivation**
|
|
**File**: `pkg/security/keymanager.go:724`
|
|
**Status**: **FIXED**
|
|
**Solution**: Replaced hardcoded salt with secure random salt generation using `crypto/rand`
|
|
**Verification**: Each key derivation now uses unique random 32-byte salt
|
|
|
|
### ✅ 4. **Compilation Errors**
|
|
**Files**: Multiple packages
|
|
**Status**: **FIXED**
|
|
**Solution**:
|
|
- Fixed missing imports and type mismatches
|
|
- Corrected function signatures and struct definitions
|
|
- Added missing fields (`IsActive` in `SecureKey`)
|
|
- Fixed KeyPermissions struct initialization
|
|
**Verification**: Main application now compiles successfully
|
|
|
|
### ✅ 5. **File Organization and Cleanup**
|
|
**Files**: Root directory clutter
|
|
**Status**: **FIXED**
|
|
**Solution**:
|
|
- Removed all `.abi` files from root directory
|
|
- Cleaned up orphaned code fragments
|
|
- Fixed syntax errors in scanner package
|
|
**Verification**: Clean file structure with proper organization
|
|
|
|
## 🚨 Remaining Critical Blockers
|
|
|
|
### ❌ 1. **Core Arbitrage Functionality Not Implemented**
|
|
**File**: `pkg/arbitrage/executor.go:335`
|
|
**Status**: **STILL BLOCKED**
|
|
**Issue**: Flash swap contract execution returns placeholder error
|
|
**Impact**: Bot cannot execute actual arbitrage opportunities
|
|
**Required**: Smart contract deployment and integration
|
|
|
|
### ❌ 2. **Missing Smart Contract Deployment**
|
|
**Status**: **PRODUCTION BLOCKER**
|
|
**Issue**: Contract bindings exist but contracts not deployed to Arbitrum
|
|
**Impact**: No actual arbitrage execution possible
|
|
**Required**: Deploy and verify contracts on Arbitrum network
|
|
|
|
### ❌ 3. **Insufficient Test Coverage**
|
|
**Status**: **PRODUCTION RISK**
|
|
**Current**: ~40% coverage
|
|
**Required**: >90% for production
|
|
**Impact**: Unvalidated edge cases and error scenarios
|
|
|
|
## 🛡️ Security Improvements Implemented
|
|
|
|
### ✅ **Key Management Security**
|
|
- Secure random salt generation for key derivation
|
|
- Encrypted private key storage with proper permissions
|
|
- Environment variable based encryption key configuration
|
|
- Active key rotation support with `IsActive` flag
|
|
|
|
### ✅ **Input Validation**
|
|
- Amount validation with overflow protection
|
|
- RPC endpoint validation with security checks
|
|
- Proper error handling and logging
|
|
|
|
### ✅ **Code Quality**
|
|
- Removed unused imports and dead code
|
|
- Fixed type safety issues
|
|
- Proper error wrapping and context
|
|
|

|
|
2. **Scaling**: Horizontal scaling and load balancing
|
|
3. **Maintenance**: Automated deployment and maintenance procedures
|
|
|
|
## 🔒 Security Verification
|
|
|
|
### Manual Verification Steps
|
|
```bash
|
|
# 1. Verify no hardcoded secrets
|
|
grep -r "private.*key.*0x" --exclude-dir=.git .
|
|
# Should return no results
|
|
|
|
# 2. Verify encryption key requirement
|
|
unset MEV_BOT_ENCRYPTION_KEY && go run cmd/mev-bot/main.go start
|
|
# Should fail with encryption key error
|
|
|
|
# 3. Verify compilation
|
|
go build cmd/mev-bot/main.go
|
|
# Should succeed without errors
|
|
|
|
# 4. Run security tests
|
|
go test ./test/security_validation_test.go -v
|
|
# Should pass all security validation tests
|
|
```
|
|
|
|
### Automated Security Checks
|
|
- `gosec ./...` - Static security analysis
|
|
- `go mod verify` - Dependency verification
|
|
- `nancy sleuth` - Vulnerability scanning
|
|
|
|
## 📋 Conclusion
|
|
|
|
**Security Status**: Significantly improved but not production-ready
|
|
|
|
The critical security vulnerabilities have been successfully addressed:
|
|
- ✅ No more hardcoded credentials
|
|
- ✅ Secure key management implementation
|
|
- ✅ Proper encryption and salt generation
|
|
- ✅ Clean compilation and file organization
|
|
|
|
However, **core functionality remains incomplete** due to missing smart contract deployment and integration. The bot has a secure foundation but cannot execute actual arbitrage until contracts are deployed and integrated.
|
|
|
|
**Recommendation**: Continue with smart contract deployment and testing phases before considering production deployment.
