Attack Surface Analysis for mutualmobile/mmdrawercontroller

Attack Surface: Unauthorized Drawer Content Access (Programmatic Bypass - Due to MMDrawerController API Misuse)

  • Description: An attacker gains access to sensitive information or functionality within the drawer due to incorrect usage of the MMDrawerController API for controlling drawer visibility. This is a direct result of how the developer interacts with the library.
    • MMDrawerController Contribution: The library provides the methods (openDrawerSide:, closeDrawerAnimated:, etc.) that, if used incorrectly, create the vulnerability. The mechanism of the drawer is directly involved.
    • Example: A developer forgets to check user authentication status before calling openDrawerSide:completion: in a specific code path, allowing an unauthenticated user to open the drawer.
    • Impact: Data breach (sensitive user information), unauthorized access to functionality.
    • Risk Severity: High to Critical (depending on the sensitivity of the exposed data/functionality).
    • Mitigation Strategies:
      • Developers:
        • Implement robust authorization checks before calling any MMDrawerController methods that control drawer visibility. This is the core mitigation.
        • Thoroughly test all code paths that interact with the MMDrawerController API, including edge cases and error conditions. Focus specifically on how authorization is handled in relation to drawer opening/closing.
        • Use a consistent and secure pattern for managing drawer state and access control. Avoid ad-hoc checks scattered throughout the codebase.
        • Consider creating a wrapper class or helper functions around MMDrawerController to centralize and enforce access control logic. This makes it easier to audit and maintain.
