Attack Tree Path: Exploit Routing Vulnerabilities [CRITICAL NODE]

  • Manipulate Route Parameters [CRITICAL NODE]:

    • Route Parameter Pollution [HIGH-RISK PATH]:

      • Attack Vector: Attackers inject unexpected or malicious parameters into the URL query string or path.
      • Mechanism: Laminas MVC routing uses parameters to determine the controller and action to execute. If applications don't properly handle or sanitize these parameters, attackers can inject parameters that alter the intended application flow or introduce vulnerabilities.
      • Example: Injecting parameters that are then used in database queries without sanitization, potentially leading to SQL injection (though the vulnerability is in application code, routing facilitates parameter delivery).
      • Mitigation: Always sanitize and validate route parameters. Use Laminas\Filter and Laminas\Validator components. Avoid directly using raw route parameters in sensitive operations.

    • Route Parameter Injection (Path Traversal) [HIGH-RISK PATH] [CRITICAL NODE]:

      • Attack Vector: Attackers inject path traversal sequences (e.g., ../, ..\\) into route parameters.
      • Mechanism: If route parameters are used to construct file paths (e.g., for file downloads or template rendering) without proper validation, attackers can use path traversal to access files outside the intended directory.
      • Example: A route like /download/file?path=user_provided_path could be exploited by setting path to ../../../../etc/passwd to access sensitive system files.
      • Mitigation: Never directly use route parameters to construct file paths. Implement strict validation and sanitization. Use whitelisting of allowed paths or filenames.

    • Bypass Route Constraints/Guards (if poorly implemented) [HIGH-RISK PATH]:

      • Attack Vector: Attackers attempt to bypass route constraints or route guards designed to restrict access to certain routes.
      • Mechanism: Laminas MVC allows defining constraints and guards to control access based on criteria like user roles or IP addresses. If these are poorly implemented, have logical flaws, or are misconfigured, attackers can bypass them.
      • Example: A route guard might check for a specific user role, but a vulnerability in the role checking logic or a misconfiguration in the guard definition could allow unauthorized access.
      • Mitigation: Thoroughly test route constraints and guards. Ensure they are correctly implemented and cover all necessary access control scenarios. Use robust authorization mechanisms within controllers and action filters.

Attack Tree Path: Exploit Controller/Action Vulnerabilities [CRITICAL NODE]

  • Access Unintended Actions (Authorization Bypass) [HIGH-RISK PATH]:

    • Attack Vector: Attackers attempt to access controller actions they are not authorized to access.
    • Mechanism: Even with secure routing, vulnerabilities can exist in controller-level authorization logic. Flaws in access control within controllers or action filters can lead to unauthorized access.
    • Example: A controller might use @IsGranted annotations, but the underlying authorization service might have a vulnerability or be misconfigured, allowing bypass.
    • Mitigation: Implement robust authorization logic within controllers and action filters. Use dedicated authorization libraries or services. Regularly audit authorization rules and logic.

  • Exploit Vulnerabilities in Action Logic [CRITICAL NODE]:

    • Input Validation Issues in Actions [HIGH-RISK PATH] [CRITICAL NODE]:
      • Attack Vector: Attackers exploit the lack of or weak input validation in controller action methods.
      • Mechanism: Even if Laminas\Form is used for form input, actions might directly process other types of input (e.g., from APIs, custom requests) without proper validation. This can lead to various injection vulnerabilities.
      • Example: An action receiving data via POST might directly use it in a database query without validation, leading to SQL injection.
      • Mitigation: Always validate all input received in actions, regardless of the source. Use Laminas\Filter and Laminas\Validator components within actions for data validation.

Attack Tree Path: Exploit View Layer Vulnerabilities (Template Engine - Laminas\View) [CRITICAL NODE]

  • Server-Side Template Injection (SSTI) [HIGH-RISK PATH] [CRITICAL NODE]:
    • Attack Vector: Attackers inject malicious template directives or code into user-controlled input that is then rendered by the template engine.
    • Mechanism: If user-provided data is directly embedded into templates without proper escaping, the template engine might interpret and execute the injected code. This can lead to Remote Code Execution (RCE).
    • Example: If user input is directly placed within template directives like {{ user_input }} without escaping, an attacker could inject template code like {{ system('whoami') }} to execute system commands.
    • Mitigation: Always escape user-provided data when rendering it in templates. Use Laminas\View's escaping mechanisms (e.g., escapeHtml(), escapeJs()). Avoid directly concatenating user input into template code. Use secure templating practices.

Attack Tree Path: Exploit Form Handling Vulnerabilities (Laminas\Form) [CRITICAL NODE]

  • Bypass Server-Side Validation (Laminas\Form Validation) [HIGH-RISK PATH]:

    • Attack Vector: Attackers attempt to bypass server-side validation rules defined in Laminas\Form.
    • Mechanism: Weak or insufficient validation rules, or logical flaws in validation logic, can allow attackers to submit malicious data that bypasses validation.
    • Example: Validation rules might not be strict enough to prevent SQL injection characters in form fields.
    • Mitigation: Implement strong server-side validation using Laminas\Form's validation features. Regularly review and update validation rules. Ensure validation rules are comprehensive and cover all potential attack vectors.

  • Input Smuggling/Injection via Form Fields [HIGH-RISK PATH]:

    • Attack Vector: Attackers inject malicious data into form fields that are not properly sanitized or validated, leading to injection vulnerabilities in backend processing.
    • Mechanism: Even if forms have some validation, if the data is not properly sanitized after validation and before being used in backend operations (like database queries or system commands), injection vulnerabilities can occur.
    • Example: Injecting SQL injection payloads into form fields that are not properly sanitized before being used in database queries, even if basic validation is present.
    • Mitigation: Sanitize and validate all form input on the server-side. Use Laminas\Filter and Laminas\Validator components for input processing. Apply context-specific sanitization based on how the data will be used (e.g., database escaping for SQL queries).

Attack Tree Path: Exploit Known Vulnerabilities in Laminas MVC or its Dependencies [CRITICAL NODE]

  • Attack Vector: Attackers exploit publicly known vulnerabilities in the specific version of Laminas MVC or its dependencies used by the application.
  • Mechanism: Software vulnerabilities are often discovered and publicly disclosed. If applications are not kept up-to-date with security patches, they become vulnerable to exploitation using readily available exploit code.
  • Example: A known vulnerability in a specific version of Laminas MVC or a dependency like laminas-view could allow remote code execution.
  • Mitigation: Stay updated with security advisories for Laminas MVC and its dependencies. Regularly update Laminas MVC and its dependencies to the latest secure versions. Implement a vulnerability management process to track and remediate known vulnerabilities.

This focused attack tree and detailed breakdown provide a prioritized view of the most critical security threats for Laminas MVC applications, enabling development teams to concentrate their security efforts on the highest-risk areas.
