  1. Identify Laminas MVC Dependencies: Use Composer (composer.json and composer.lock) to list all project dependencies, specifically focusing on laminas/* packages and their transitive dependencies.
  2. Check for Laminas Security Advisories: Regularly monitor Laminas Project's security advisories and release notes for any reported vulnerabilities in Laminas MVC components or related libraries.
  3. Update Laminas Packages: Utilize Composer to update outdated Laminas packages using composer update laminas/*.
  4. Test Laminas MVC Functionality: After updating Laminas packages, thoroughly test core Laminas MVC functionalities, including routing, controllers, views, forms, and database interactions, to ensure compatibility and prevent regressions.
  5. Deploy Updated Laminas MVC: Once testing is successful, deploy the updated application with the latest Laminas MVC components to the production environment.
• Threats Mitigated:
  • Known Vulnerabilities in Laminas MVC and Dependencies (High Severity): Exploits targeting publicly disclosed vulnerabilities specifically within Laminas MVC framework code or its direct dependencies.
• Impact:
  • Known Vulnerabilities in Laminas MVC and Dependencies: High - Significantly reduces the risk of exploitation of known vulnerabilities within the framework itself.
• Currently Implemented: Partially implemented. Laminas MVC updates are performed manually during general dependency updates, but not always immediately after Laminas security advisories.
  • Location: Project's development and deployment process, composer.json.
• Missing Implementation: Establish a process for proactively monitoring Laminas security advisories and applying updates specifically for Laminas components more frequently.

Mitigation Strategy: Secure Configuration Management

• Mitigation Strategy: Secure Configuration Management
• Description:
  1. Externalize Laminas MVC Specific Configuration: Identify sensitive configuration parameters within Laminas MVC configuration files (module.config.php, autoload/*.config.php, etc.), such as database credentials used by Laminas DB, API keys used in Laminas services, and any security-related settings.
  2. Environment Variables for Laminas Configuration: Utilize environment variables to override sensitive configuration values defined in Laminas MVC configuration files. Access these variables within Laminas configuration arrays using placeholders or environment variable retrieval functions.
  3. Secure Storage for Laminas Configuration: Ensure that the environment where these variables are stored (server environment, container environment, secret management tools) is securely managed and access is restricted.
  4. Avoid Hardcoding in Laminas Configuration: Refrain from hardcoding sensitive information directly within Laminas MVC configuration files.
• Threats Mitigated:
  • Exposure of Sensitive Credentials in Laminas Configuration (High Severity): Accidental or intentional exposure of credentials within Laminas MVC configuration files, leading to unauthorized access to resources managed by the application.
• Impact:
  • Exposure of Sensitive Credentials in Laminas Configuration: High - Significantly reduces the risk of credential exposure specifically within the application's Laminas MVC configuration.
• Currently Implemented: Partially implemented. Database credentials used by Laminas DB are stored as environment variables and accessed in Laminas DB configuration. Some API keys used in Laminas services might still be in configuration files.
  • Location: .env file, config/autoload/db.local.php, other config/autoload/*.local.php files.
• Missing Implementation: Migrate all sensitive configurations used within Laminas MVC components (API keys, service credentials, etc.) to environment variables or a dedicated secret management solution, ensuring they are not directly present in configuration files.

Mitigation Strategy: Disable Debugging and Development Tools in Production

• Mitigation Strategy: Disable Debugging and Development Tools in Production
• Description:
  1. Disable Laminas Development Modules: Ensure modules like ZendDeveloperTools (if used) and any custom debugging modules built for Laminas MVC are explicitly disabled in the production modules.config.php or application configuration.
  2. Configure Laminas Error Handling: Configure Laminas MVC's error handling to prevent detailed error messages from being displayed to users in production. Utilize Laminas's error handling mechanisms to log errors securely and display generic error pages.
  3. Remove Laminas Debugging Code: Review controllers, views, and services for any debugging code specific to Laminas MVC (e.g., var_dump() of Laminas objects, logging statements intended only for development within Laminas components) and remove them before production deployment.
• Threats Mitigated:
  • Information Leakage via Laminas MVC Error Handling (Medium Severity): Exposure of internal application details, file paths, Laminas MVC structure, or database information through detailed error messages generated by Laminas MVC, aiding attackers in reconnaissance.
• Impact:
  • Information Leakage via Laminas MVC Error Handling: Medium - Significantly reduces the risk of information leakage through Laminas MVC's error reporting in production.
• Currently Implemented: Partially implemented. ZendDeveloperTools is disabled in production configuration. Basic error handling is in place, but might still expose some framework-specific details in certain error scenarios.
  • Location: config/modules.config.php, Laminas MVC error handling configuration (if customized).
• Missing Implementation: Implement robust custom error handling within Laminas MVC to ensure generic error pages are displayed and framework-specific error details are suppressed in production. Thoroughly remove all Laminas MVC related debugging code before each production deployment.

Mitigation Strategy: Strict Route Definition and Validation

• Mitigation Strategy: Strict Route Definition and Validation
• Description:
  1. Explicit Laminas MVC Route Definitions: Define routes explicitly in module.config.php using Laminas MVC's routing configuration. Avoid overly permissive wildcard routes that could expose unintended controller actions or modules within the Laminas MVC application.
  2. Parameter Constraints in Laminas Routes: Utilize route constraints within Laminas MVC route definitions (regular expressions or custom validators) to restrict the allowed values for route parameters, ensuring they conform to expected formats and types as processed by Laminas MVC.
  3. Input Filtering using Laminas InputFilter in Controllers: In Laminas MVC controller actions, use Laminas InputFilter component to validate route parameters after they are extracted from the route match. This ensures data integrity within the Laminas MVC request handling pipeline.
  4. Sanitization and Escaping of Route Parameters in Laminas MVC Context: Sanitize and escape route parameters before using them in database queries (if using Laminas DB) or displaying them in views (using Laminas View Helpers) to prevent injection vulnerabilities within the Laminas MVC application flow.
• Threats Mitigated:
  • Unintended Functionality Exposure via Laminas Routing (Medium Severity): Overly permissive Laminas MVC routes can expose controller actions or modules that were not intended to be publicly accessible, potentially leading to security vulnerabilities.
  • Injection Vulnerabilities via Laminas Route Parameters (High Severity): Lack of validation and sanitization of route parameters within the Laminas MVC request lifecycle can lead to SQL injection (if used in Laminas DB queries) or XSS vulnerabilities (if output in Laminas views) if not handled properly within the Laminas MVC framework.
• Impact:
  • Unintended Functionality Exposure via Laminas Routing: Medium - Reduces the risk of exposing unintended functionalities through Laminas MVC routing.
  • Injection Vulnerabilities via Laminas Route Parameters: High - Significantly reduces the risk of injection vulnerabilities arising from route parameters processed by Laminas MVC.
• Currently Implemented: Partially implemented. Laminas MVC routes are mostly explicitly defined. Basic parameter constraints are used in some routes. Input filtering using Laminas InputFilter in controllers is not consistently applied to route parameters.
  • Location: module.config.php (routing configuration), Laminas MVC Controller actions.
• Missing Implementation: Implement comprehensive input filtering for all route parameters within Laminas MVC controllers using Laminas InputFilter. Review and refine Laminas MVC route definitions to ensure they are as specific as possible and avoid unnecessary wildcards.
