Threat Model Analysis for cakephp/cakephp

Threat: Component Configuration Bypass (Authentication)

  • Description: An attacker exploits misconfigured AuthenticationComponent settings. They might:
    • Bypass authentication entirely by crafting requests that don't trigger the authentication checks (e.g., exploiting misconfigured loginAction or unauthenticatedRedirect).
    • Use default or weak credentials if custom authenticators are poorly implemented.
    • Manipulate session data if session handling is not properly secured within the component.
    • Exploit weaknesses in custom password hashing (if used instead of CakePHP's defaults).
  • Impact: Unauthorized access to protected resources, data breaches, complete system compromise.
  • Affected Component: AuthenticationComponent, specifically its configuration and any custom authenticators used.
  • Risk Severity: Critical
  • Mitigation Strategies:
    • Explicitly configure all relevant AuthenticationComponent settings. Do not rely solely on defaults.
    • Thoroughly test all authentication flows, including edge cases and error handling.
    • Use strong password hashing (CakePHP's defaults are generally good, but verify).
    • Ensure proper session management (CakePHP handles this well by default, but custom code could introduce issues).
    • Regularly review the authentication configuration.

Threat: Authorization Rule Bypass

  • Description: An attacker gains access to resources they should not have access to due to incorrectly defined authorization rules within the AuthorizationComponent or custom authorization logic. They might:
    • Access controller actions that lack authorization checks.
    • Exploit flaws in custom authorization logic (e.g., incorrect role comparisons).
    • Bypass authorization checks by manipulating request parameters.
  • Impact: Privilege escalation, unauthorized data access/modification, potential for further attacks.
  • Affected Component: AuthorizationComponent, custom authorization logic (e.g., policy objects, isAuthorized() methods).
  • Risk Severity: High
  • Mitigation Strategies:
    • Implement authorization checks on every controller action that requires protection.
    • Use a consistent authorization strategy (e.g., policy objects) throughout the application.
    • Thoroughly test all authorization rules, including edge cases.
    • Avoid overly complex authorization logic.
    • Regularly review authorization rules for potential weaknesses.

Threat: Plugin Vulnerability Exploitation

  • Description: An attacker exploits a vulnerability within a third-party CakePHP plugin. The plugin might have:
    • SQL injection vulnerabilities (if it interacts with the database directly).
    • Cross-site scripting (XSS) vulnerabilities (if it generates HTML output).
    • Other vulnerabilities specific to the plugin's functionality. Because plugins can integrate deeply with CakePHP, vulnerabilities can have wide-ranging effects.
  • Impact: Varies depending on the plugin's functionality, but could range from data breaches to complete system compromise.
  • Affected Component: The vulnerable third-party plugin. This could affect any part of the application that uses the plugin.
  • Risk Severity: High (potentially Critical, depending on the plugin)
  • Mitigation Strategies:
    • Use only trusted and well-maintained plugins.
    • Carefully review the code of any third-party plugins.
    • Keep plugins updated to the latest versions.
    • Monitor plugin repositories for security advisories.
    • Consider forking and maintaining critical plugins internally.

Threat: Debug Mode Exposure

  • Description: An attacker accesses the application with debug mode enabled, revealing sensitive information about the application's internal state, including:
    • Database credentials.
    • File paths.
    • Source code snippets.
    • Stack traces.
  • Impact: Information disclosure, potential for further attacks (e.g., SQL injection, code execution). This is a direct result of a CakePHP configuration setting.
  • Affected Component: The entire CakePHP application. Debug mode affects how errors are handled and what information is displayed.
  • Risk Severity: Critical
  • Mitigation Strategies:
    • Never enable debug mode in a production environment.
    • Configure custom error handlers to display generic error messages.
    • Log detailed error information to a secure location.

Threat: Console Command Injection

  • Description: An attacker provides malicious input to a CakePHP console command, leading to unintended code execution or system compromise. They might:
    • Inject shell commands into arguments passed to the console command.
    • Exploit vulnerabilities in the command's input parsing logic. This is a direct threat to CakePHP's console command functionality.
  • Impact: Code execution, system compromise, data breaches.
  • Affected Component: CakePHP console commands (bin/cake), specifically those that accept user input and interact with the system.
  • Risk Severity: High
  • Mitigation Strategies:
    • Treat all console command input as untrusted.
    • Sanitize and validate all input before using it.
    • Avoid using shell commands within console commands if possible. Use CakePHP's Process class with proper escaping if necessary.
    • Restrict access to the console to authorized users.
