Security improvements to prevent potential issues:
1. Port Validation (normalize_port):
- Validate port range is 1-65535
- Use Integer.parse instead of String.to_integer to prevent crashes
- Return default port 161 for any invalid input
2. SNMP Test Validation (validate_test_snmp_input):
- Validate IP address format before allowing SNMP tests
- Require non-empty community string
- Prevent network scanning with invalid/missing IPs
- Return clear error messages for validation failures
These changes ensure user input is properly validated and prevent:
- Integer overflow/underflow with ports
- Process crashes from invalid input
- Unauthorized network scanning via SNMP test feature
- SNMP requests with missing credentials
Implement comprehensive admin interface allowing designated superusers to view all users and organizations, impersonate users for debugging, and perform administrative operations. All superuser actions are tracked in audit logs for compliance.
Features:
- Superuser authentication with dedicated admin routes at /admin
- User impersonation with session state preservation
- Admin dashboard with system statistics
- User and organization management interfaces
- Comprehensive audit logging with IP tracking
- Visual impersonation banner with exit capability
- Security controls preventing self-impersonation and superuser-to-superuser impersonation
Database:
- Add is_superuser boolean field to users table
- Create audit_logs table for tracking sensitive operations
- Set graham@mcintire.me as initial superuser
