Attack Tree Path: Attack Goal: Compromise Uno Platform Application

Attack Vectors: All paths in the attack tree ultimately lead to this goal. Mitigation Focus: Comprehensive security strategy covering all identified attack vectors.

Attack Tree Path: Exploit Uno Platform Specific Vulnerabilities

Attack Vectors: Exploiting weaknesses inherent to the Uno Platform's design, implementation, or platform bridges. Mitigation Focus: Regular Uno Platform updates, security audits of Uno core code, secure coding practices within the Uno Platform project.

Attack Tree Path: Memory Corruption Bugs in Uno Runtime

Attack Vectors: * Buffer Overflows: Sending maliciously crafted XAML with oversized elements or strings to overflow memory buffers during parsing or rendering. * Use-After-Free: Triggering specific sequences of UI element creation and destruction to exploit memory management flaws, leading to use of freed memory. Mitigation Focus: * Memory safety checks in Uno runtime code. * Fuzzing the XAML parser and rendering engine. * Regular Uno Platform updates to patch memory corruption vulnerabilities.

Attack Tree Path: Logic Errors in Uno Platform Core Logic

Attack Vectors: * XAML Binding Engine Vulnerabilities: Crafting malicious XAML bindings that exploit logic flaws in the binding engine to execute code or manipulate data. * Flaws in Event Handling Mechanism: Exploiting vulnerabilities in how events are handled to bypass security checks or trigger unintended actions. Mitigation Focus: * Regular security audits of Uno core logic, especially binding and event handling. * Secure XAML coding practices to avoid logic vulnerabilities. * Input validation for XAML and resources to prevent malicious input from exploiting logic flaws.

Attack Tree Path: Vulnerabilities in Platform-Specific Uno Implementations (WebAssembly/Native Bridges)

Attack Vectors: Exploiting weaknesses in the code that bridges Uno Platform's core logic with platform-specific APIs and functionalities (browser APIs for WebAssembly, OS APIs for native platforms). Mitigation Focus: * Secure coding practices in platform bridge implementations. * Rigorous testing on all target platforms to identify platform-specific bugs. * Input validation at platform bridge boundaries to prevent injection attacks.

Attack Tree Path: Inadequate Input Validation in Platform Bridges

Attack Vectors: * Injection vulnerabilities: Passing unvalidated data from Uno code to platform-specific code, allowing attackers to inject malicious commands or code into platform APIs. Mitigation Focus: * Implement robust input validation for all data crossing the platform bridge. * Secure coding practices to prevent injection vulnerabilities in platform-specific code.

Attack Tree Path: Exploit Uno Platform Build and Deployment Process Vulnerabilities

Attack Vectors: Compromising the processes used to build and deploy Uno Platform applications, leading to the distribution of malicious or vulnerable applications. Mitigation Focus: Secure the entire build and deployment pipeline, from code repositories to production servers.

Attack Tree Path: Supply Chain Attacks targeting Uno Platform Dependencies

Attack Vectors: * Compromised NuGet Packages: Injecting malicious code into NuGet packages used by the Uno Platform or the application itself, leading to code execution during build or within the deployed application. Mitigation Focus: * Dependency scanning and vulnerability management to detect compromised packages. * Secure build pipeline with integrity checks for dependencies. * Verify integrity of Uno Platform tools and templates. * Use signed NuGet packages to ensure authenticity.

Attack Tree Path: Misconfiguration of Uno Platform Application Deployment

Attack Vectors: Exploiting misconfigurations in the deployment environment to gain unauthorized access or compromise the application. Mitigation Focus: Secure deployment configurations and regular security audits of deployment environments.

Attack Tree Path: Insecure Server Configurations for WebAssembly Deployment

Attack Vectors: * Web Server Misconfigurations: Exploiting misconfigured web servers hosting the Uno WebAssembly application to access server files, manipulate application assets, or perform server-side attacks. Mitigation Focus: * Secure server configuration following security hardening guides. * Regular security audits of server configurations.

Attack Tree Path: Vulnerabilities in Custom Uno Platform Extensions or Libraries -> Vulnerabilities in Application-Specific Uno Platform Code

Attack Vectors: Exploiting coding errors or security flaws in the application's own C# and XAML code that interacts with the Uno Platform. This is often the most likely attack vector due to application-specific code being less rigorously tested than core platform code. Mitigation Focus: * Secure coding practices for all application-specific Uno code. * Security reviews and code audits of application code. * Regular testing, including penetration testing, of the application.

Attack Tree Path: Vulnerabilities in NuGet Packages used by the Application (Beyond Uno Core) -> Known Vulnerabilities in Third-Party Libraries

Attack Vectors: Exploiting known vulnerabilities in third-party NuGet packages used by the application (libraries beyond the core Uno Platform). Mitigation Focus: * Dependency scanning and vulnerability management to identify known vulnerabilities in NuGet packages. * Regular updates of NuGet packages to patch known vulnerabilities. * SBOM (Software Bill of Materials) management to track dependencies and their vulnerabilities.
