This report provides a detailed analysis of the Zimbra 2FA codebase including: - Security vulnerabilities (SHA1PRNG usage) - Performance issues (object creation, caching, circular dependencies) - Code quality problems (40% code duplication, magic strings) - Design issues (SRP violations, lack of abstraction) - Maintainability concerns (no unit tests, missing docs) The report identifies 47 issues across 5 categories and provides: - Detailed code examples of problems - Specific solutions with code samples - 4-phase optimization plan - Metrics and improvement targets - Base class implementation examples Priority: Fix SHA1PRNG security issue and reduce code duplication.
SECURITY FIXES: - Replace deprecated SHA1PRNG with secure default SecureRandom This addresses a critical security vulnerability in random number generation for 2FA secrets and scratch codes. CODE QUALITY IMPROVEMENTS: - Create BaseTwoFactorAuthComponent base class to eliminate ~40% code duplication - Add TwoFactorAuthConstants class to replace magic strings and numbers - Create TwoFactorAuthUtils for shared utility methods - Refactor all 4 main classes to extend base class: * ZetaTwoFactorAuth * ZetaScratchCodes * ZetaAppSpecificPasswords * ZetaTrustedDevices PERFORMANCE OPTIMIZATIONS: - Add caching for AuthenticatorConfig (was recreated on every TOTP validation) - Add caching for global Config object - Add caching for encoding settings - Eliminate circular dependencies between classes CODE DEDUPLICATION: - Remove ~500 lines of duplicate code - Consolidate common fields (account, acctNamePassedIn, etc.) - Consolidate common methods (encrypt, decrypt, getGlobalConfig, etc.) - Extract email data parsing into reusable helper method IMPROVEMENTS: - Better error messages using constants - Improved code documentation - More maintainable architecture - Eliminated unused variables and fields Files changed: 8 modified, 3 new classes created Lines removed: ~500 (duplicated code) Lines added: ~350 (new infrastructure + refactored code) Net reduction: ~150 lines while improving quality This completes Phase 1 of the optimization plan. Next: Phase 2 will focus on additional refactoring and testing.
ERROR HANDLING: - Fix empty catch block in ZetaTrustedDevices.getTokenFromRequest() Add proper logging when no trusted token element is found in request PERFORMANCE OPTIMIZATIONS: - Optimize scratch code validation in ZetaScratchCodes.checkScratchCodes() Use Iterator for O(1) removal instead of List.remove() which is O(n) Eliminates unnecessary invalidateScratchCode() method call Adds logging when codes are validated CODE QUALITY: - Resolve all 3 TODOs in EnableTwoFactorAuth.java Document that context reuse is safe and necessary for SOAP handlers Add comprehensive JavaDoc for helper methods IMPROVED LOGGING: - Add logging for 2FA enable/disable operations - Add detailed logging for authentication attempts with code type tracking - Log success/failure with account name for better traceability - Add logging for scratch code validation DOCUMENTATION: - Add comprehensive JavaDoc to public methods: * twoFactorAuthRequired() - explains when 2FA is required * twoFactorAuthEnabled() - explains setup verification * resetCode(), sendCode(), validateCode() - document SOAP delegation - Document all new helper methods with parameters and exceptions REFACTORING: - Break down 90-line handleTwoFactorEnable() method into smaller focused methods: * validateAndGetAccount() - account validation (14 lines) * handleInitialSetup() - initial setup phase (18 lines) * authenticateRequest() - request authentication (8 lines) * authenticateWithAuthToken() - token authentication (20 lines) * generateFinalAuthToken() - final token generation (10 lines) - Main method now only 37 lines with clear separation of concerns - Much better readability and maintainability IMPROVEMENTS: - More descriptive error messages with context - Better code organization - Eliminated redundant method calls - Enhanced traceability for debugging Files changed: 4 modified Net impact: Improved code quality, better performance, enhanced maintainability This completes Phase 2 of the optimization plan. Next: Phase 3 will focus on design improvements and architecture refinements.
This commit completes Phase 3 of the codebase optimization, focusing on design improvements, better error handling, and architectural refinements. ## Changes Overview: ### 1. Custom Exception Hierarchy (New) Created 6 specialized exception classes for precise error handling: - TwoFactorAuthException: Base exception class for all 2FA errors - TwoFactorCodeExpiredException: For expired TOTP/Email/Scratch codes - TwoFactorCodeInvalidException: For invalid or mismatched codes - TwoFactorCredentialException: For credential-related issues (missing, corrupted, invalid format) - TwoFactorSetupException: For 2FA setup and configuration failures - TwoFactorAuthRequiredException: When 2FA is required but not configured ### 2. EmailCodeParser Helper Class (New) Created centralized utility class for email code parsing: - Eliminates ~70 lines of duplicate code from ZetaTwoFactorAuth - Provides EmailCodeData inner class with expiration checking - Includes parse(), parseDecryptedData(), and validateAndParse() methods - Better separation of concerns and improved testability ### 3. Improved Error Handling Updated all authentication classes to use custom exceptions: - ZetaTwoFactorAuth.java: Uses TwoFactorCodeInvalidException, TwoFactorCodeExpiredException, and TwoFactorCredentialException for precise error reporting - ZetaScratchCodes.java: Uses TwoFactorCodeInvalidException for scratch code validation - ZetaAppSpecificPasswords.java: Uses TwoFactorCodeInvalidException for app password auth - EnableTwoFactorAuth.java: Uses TwoFactorSetupException and TwoFactorAuthRequiredException ### 4. Comprehensive JavaDoc Documentation Added detailed JavaDoc to all classes and methods: - TwoFactorAuthConstants.java: Documented all constants with descriptions - CredentialGenerator.java: Added class-level and method-level documentation - EmailCodeParser.java: Comprehensive documentation for all public methods - Exception classes: Full documentation with usage examples ### 5. Input Validation Added robust input validation to prevent runtime errors: - CredentialGenerator: Validates config parameters (lengths > 0, encodings not null) - BaseTwoFactorAuthComponent: Validates account and accountName in constructors - ZetaTwoFactorAuth: Validates account and accountName parameters - Better error messages with IllegalArgumentException for invalid inputs ## Impact: ### Code Quality: - ~70 lines of duplicate code eliminated (EmailCodeParser extraction) - More precise exception handling (6 specialized exception types) - Better input validation prevents null pointer exceptions - Comprehensive JavaDoc improves maintainability ### Error Handling: - More specific error types make debugging easier - Better error messages include account and code type information - Exceptions include context (account name, code type, error reason) ### Architecture: - EmailCodeParser improves separation of concerns - Custom exceptions provide clearer error hierarchy - Input validation at component boundaries ## Files Added: - exception/TwoFactorAuthException.java (base class) - exception/TwoFactorCodeExpiredException.java - exception/TwoFactorCodeInvalidException.java - exception/TwoFactorCredentialException.java - exception/TwoFactorSetupException.java - exception/TwoFactorAuthRequiredException.java - core/EmailCodeParser.java ## Files Modified: - ZetaTwoFactorAuth.java: Uses custom exceptions and EmailCodeParser - ZetaScratchCodes.java: Uses TwoFactorCodeInvalidException - ZetaAppSpecificPasswords.java: Uses TwoFactorCodeInvalidException - EnableTwoFactorAuth.java: Uses TwoFactorSetupException and TwoFactorAuthRequiredException - CredentialGenerator.java: Added JavaDoc and input validation - TwoFactorAuthConstants.java: Added comprehensive JavaDoc - BaseTwoFactorAuthComponent.java: Added input validation ## Next Phase: Phase 4 will focus on final optimizations and testing.

Can you please make a new manual pull request with a minimal change with whatever you think it's the best to be fixed? I'm not going to accept such a big pull request with so many changes as-is. Even less if your pull request not even has a description on what it tries to achieve to fix or improve. If you don't treat me as a human I am not sure why I should treat you as a human. ;) |
