Attack Tree Analysis for bevyengine/bevy

Objective: Gain unauthorized control or cause disruption to a Bevy-based application by exploiting vulnerabilities inherent in the Bevy engine or its ecosystem.

Attack Tree Path: [CRITICAL NODE] Exploit Bevy Engine Vulnerabilities [CRITICAL NODE]

  • Attack Vectors:
    • Memory Corruption Vulnerabilities: Exploiting memory safety bugs within Bevy's core engine, potentially in unsafe Rust code or FFI interactions.
      • Malicious Asset (Model, Texture, Scene): Crafting malicious assets to trigger buffer overflows or other memory corruption issues during asset loading and parsing.
      • Crafted Network Message: Sending malformed network packets to networked Bevy applications to exploit buffer overflows in network handling code.
      • Malicious Shader Code: Injecting malicious shader code (if custom shaders are used) to cause memory corruption during shader compilation or execution.
    • Denial of Service (DoS) via Resource Exhaustion: Overloading the Bevy application by exploiting resource-intensive features.
      • Send Excessive Number of Entities/Components: Flooding the application with a massive number of entities and components to exhaust memory or processing power.
      • Load Extremely Complex Assets: Loading excessively complex assets (models, scenes) to overwhelm asset loading and rendering pipelines.
      • Trigger Computationally Expensive Physics or Rendering Scenarios: Manipulating game logic or input to create computationally intensive physics simulations or rendering tasks, leading to performance degradation or crashes.

Attack Tree Path: [CRITICAL NODE] Exploit Bevy Ecosystem/Plugin Vulnerabilities [CRITICAL NODE]

  • Attack Vectors:
    • Vulnerable Bevy Plugins: Exploiting vulnerabilities within Bevy plugins used by the application.
      • Leverage Known Vulnerability in Plugin: Utilizing publicly known vulnerabilities in outdated or poorly maintained plugins.
      • Plugin Dependency Analysis (Crate versions, known vulnerabilities): Identifying vulnerable plugins by analyzing their dependencies and known vulnerabilities in those dependencies.
    • Dependency Vulnerabilities in Bevy or Plugins: Exploiting vulnerabilities in the Rust crates that Bevy or its plugins depend on.
      • Leverage Known Vulnerability in Dependency: Utilizing publicly known vulnerabilities in outdated dependencies of Bevy or its plugins.
      • Dependency Scanning Tools (cargo audit, etc.): Identifying vulnerable dependencies using automated scanning tools like cargo audit.

Attack Tree Path: [CRITICAL NODE] Exploit Asset Loading/Handling Vulnerabilities [CRITICAL NODE]

  • Attack Vectors:
    • Malicious Asset Injection: Injecting malicious assets into the application's asset loading pipeline.
      • Replace Legitimate Asset with Malicious Asset: Replacing existing, legitimate assets with crafted malicious ones to be loaded by the application.
      • Introduce New Malicious Asset into Asset Loading Path: Adding new malicious assets to directories or paths where the application loads assets from.
    • Asset Parsing Vulnerabilities: Exploiting vulnerabilities in the code that parses asset files (images, models, scenes).
      • Craft Malicious Asset to Exploit Parsing Logic (Buffer Overflows, Integer Overflows, etc.): Creating specially crafted asset files designed to trigger buffer overflows, integer overflows, or other parsing errors that can lead to memory corruption or code execution.
