Threat Model Analysis for jetbrains/compose-jb

Threat: Dependency Vulnerability Exploitation

  • Description: An attacker exploits a known vulnerability in a dependency used directly by Compose for Desktop, such as Skia or a specific Kotlin library used internally. They might craft malicious input or trigger specific application behavior that exploits the vulnerability within the Compose-jb framework, leading to code execution or other malicious outcomes within the desktop application.
  • Impact: Remote Code Execution (RCE), Denial of Service (DoS), Privilege Escalation, Information Disclosure.
  • Compose-jb Component Affected: Compose for Desktop framework core, including its internal dependencies like Skia rendering engine and Kotlin libraries.
  • Risk Severity: Critical
  • Mitigation Strategies:
    • Regularly update Compose for Desktop framework to the latest versions.
    • Implement Software Composition Analysis (SCA) specifically to monitor dependencies used by Compose for Desktop.
    • Subscribe to security advisories related to JetBrains Compose for Desktop and its core dependencies.
    • Apply security patches released by JetBrains or upstream dependencies promptly.

Threat: Platform-Specific Implementation Bug Exploitation

  • Description: An attacker leverages a critical bug or vulnerability specific to a particular operating system's native integration within Compose for Desktop (Windows, macOS, Linux). This could involve exploiting flaws in how Compose-jb interacts with platform-specific APIs for window management, input handling, or accessibility, leading to crashes, unexpected behavior, or potentially privilege escalation on the target platform.
  • Impact: Denial of Service (DoS), Platform-specific crashes, Privilege Escalation (in severe cases).
  • Compose-jb Component Affected: Platform-specific native bindings and integration modules within Compose for Desktop framework.
  • Risk Severity: High
  • Mitigation Strategies:
    • Thoroughly test the application on all target platforms, focusing on platform-specific features and integrations of Compose for Desktop.
    • Stay updated with Compose for Desktop releases and bug fixes, prioritizing platform-related security updates.
    • Implement platform-specific security hardening measures where applicable to mitigate potential exploitation of OS-level vulnerabilities exposed through Compose-jb integration.
    • Report any platform-specific bugs or unexpected behavior to the Compose for Desktop development team for investigation and patching.

Threat: Insecure Native Code Integration via Compose-jb Interoperability

  • Description: If a Compose for Desktop application utilizes Compose-jb's interoperability features to integrate with native code (e.g., using LocalWindow.current.rootPane.contentPane.add(...) for AWT/Swing integration or platform channels for direct native calls), vulnerabilities in the integrated native code can be exploited through the Compose-jb application. An attacker could leverage the Compose-jb application as an entry point to trigger vulnerabilities like buffer overflows or insecure system calls within the custom native code, gaining control over the system.
  • Impact: Remote Code Execution (RCE), Privilege Escalation, Data Corruption, System Compromise.
  • Compose-jb Component Affected: Compose for Desktop interoperability APIs and mechanisms that facilitate integration with external native code or libraries.
  • Risk Severity: Critical
  • Mitigation Strategies:
    • Minimize the necessity for native code integration within Compose for Desktop applications.
    • Conduct rigorous security audits and penetration testing of all native code components integrated with Compose-jb applications.
    • Enforce secure coding practices for all native code, including memory safety, robust input validation, and least privilege principles.
    • Isolate native code execution with appropriate sandboxing or security boundaries to limit the impact of potential vulnerabilities.
    • Carefully review and restrict the permissions granted to native code integrations within the Compose-jb application context.

Threat: UI Rendering Engine (Skia) Vulnerability Exploitation via Compose-jb

  • Description: An attacker crafts specific UI elements or interactions within a Compose for Desktop application that exploit a critical vulnerability in the Skia rendering engine, which is a core component of Compose-jb responsible for UI rendering. By manipulating the UI through user input or application logic, the attacker could trigger a vulnerability in Skia's rendering process, potentially leading to code execution within the application's context or a denial of service due to rendering engine crashes.
  • Impact: Remote Code Execution (RCE), Denial of Service (rendering engine crashes), UI manipulation leading to application instability.
  • Compose-jb Component Affected: Skia rendering engine as integrated and utilized by Compose for Desktop framework for UI rendering.
  • Risk Severity: High
  • Mitigation Strategies:
    • Keep Compose for Desktop framework and its bundled Skia version updated to the latest releases, ensuring timely application of security patches for Skia vulnerabilities.
    • Monitor security advisories specifically related to Skia and graphics rendering engines, especially in the context of Compose for Desktop usage.
    • Avoid utilizing experimental or potentially unstable UI features within Compose for Desktop that might rely on less hardened or more vulnerable parts of the Skia rendering engine.
    • Implement robust input validation and sanitization within the application, even for UI-related inputs, to prevent potential injection attacks that could trigger rendering engine vulnerabilities.
