Attack Tree Path: Exploit Asset Loading Vulnerabilities - Malicious Asset Injection - Bypass Input Validation on Asset Upload

  • Attack Vector:
    • Attacker uploads a specially crafted malicious asset file (e.g., modified 3D model, texture, scene, audio file) to the application.
    • The application's input validation for asset uploads is bypassed, allowing the malicious file to be processed.
    • rg3d engine then parses this malicious asset.
  • Critical Node: Bypass Input Validation on Asset Upload - Failure to properly validate uploaded files is the key enabler for this attack.
  • Impact: Code Execution, Denial of Service, Memory Corruption - Exploiting vulnerabilities in asset parsers can lead to severe consequences.

Attack Tree Path: Exploit Asset Loading Vulnerabilities - Malicious Asset Injection - rg3d Parses Malicious Asset - Exploit Buffer Overflow in Asset Parser (Mesh, Texture, Scene, Audio, Integer Overflow/Underflow)

  • Attack Vector:
    • Attacker provides a malicious asset file (either uploaded or from a compromised source).
    • rg3d engine's asset parsers (for mesh, texture, scene, audio formats) contain buffer overflow or integer overflow/underflow vulnerabilities.
    • Parsing the malicious asset triggers these vulnerabilities.
  • Critical Node: rg3d Parses Malicious Asset - This is the point where the engine's parsing logic becomes vulnerable.
  • Critical Node: Exploit Buffer Overflow in Asset Parser - Buffer overflows are the primary vulnerability type in this path.
  • Impact: Code Execution, Denial of Service, Memory Corruption - Successful exploitation of buffer overflows allows attackers to control program execution.

Attack Tree Path: Exploit Asset Loading Vulnerabilities - Asset Path Traversal - Manipulate Asset Paths via User Input - Bypass Path Sanitization/Validation

  • Attack Vector:
    • Application allows users to specify asset paths (directly or indirectly).
    • Attacker manipulates these paths to include path traversal sequences (e.g., ../, ../../).
    • Application fails to properly sanitize or validate these paths.
    • rg3d engine loads assets based on the manipulated paths.
  • Critical Node: Manipulate Asset Paths via User Input - Allowing user control over asset paths opens the door for path traversal.
  • Critical Node: Bypass Path Sanitization/Validation - Failure to sanitize user-provided paths is the key weakness.
  • Impact: Information Disclosure, Configuration Data Theft, Access to Server-Side Files (if applicable) - Attackers can read sensitive files outside the intended asset directories.

Attack Tree Path: Exploit Engine Vulnerabilities - Exploit Resource Management Issues in Renderer - Trigger Resource Exhaustion

  • Attack Vector:
    • Attacker crafts a scene or game content that intentionally overloads the rendering pipeline.
    • This can be achieved by including excessive numbers of objects, draw calls, textures, or complex shaders.
    • rg3d engine attempts to render this content, leading to resource exhaustion (GPU or CPU).
  • Impact: Denial of Service - The application becomes unresponsive or crashes due to resource overload.

Attack Tree Path: Exploit Physics Engine Vulnerabilities - Trigger Physics Engine Crashes - Supply Malformed Physics Data

  • Attack Vector:
    • Attacker provides malformed or extreme physics data (e.g., objects with infinite mass, extreme velocities, invalid shapes).
    • rg3d engine's physics engine (Rapier) attempts to simulate this data.
    • Malformed data triggers crashes or unexpected behavior in the physics engine.
  • Impact: Denial of Service, Unpredictable Game Behavior - The application becomes unstable or crashes due to physics engine errors.

Attack Tree Path: Exploit Scripting Engine Vulnerabilities - Script Injection - Bypass Script Input Sanitization

  • Attack Vector:
    • Application uses scripting and allows user input to influence script execution.
    • Attacker injects malicious script code through user input.
    • Application fails to sanitize script inputs, allowing malicious code to be executed within the scripting engine's context.
  • Critical Node: Bypass Script Input Sanitization - Failure to sanitize script inputs enables script injection.
  • Impact: Code Execution (Scripting Engine Context), Data Access, Application Logic Manipulation - Attackers can control game logic, access data, or potentially escalate privileges.

Attack Tree Path: Exploit Networking Vulnerabilities - Exploit Network Protocol Vulnerabilities - Buffer Overflows in Packet Parsing

  • Attack Vector:
    • Application uses rg3d networking features and implements a custom network protocol.
    • The network protocol parsing logic in rg3d or the application contains buffer overflow vulnerabilities.
    • Attacker sends specially crafted network packets that trigger these buffer overflows during parsing.
  • Critical Node: Buffer Overflows in Packet Parsing - Buffer overflows in network packet handling are the core vulnerability.
  • Impact: Code Execution, Denial of Service - Exploiting buffer overflows in network code can lead to remote code execution or application crashes.

Attack Tree Path: Exploit Networking Vulnerabilities - Lack of Encryption/Authentication

  • Attack Vector:
    • Application uses rg3d networking without implementing encryption or authentication.
    • Network communication is vulnerable to eavesdropping and tampering.
    • Attacker performs Man-in-the-Middle attacks to intercept or modify network traffic.
  • Impact: Man-in-the-Middle Attacks, Data Interception, Data Tampering - Sensitive game data or user information can be compromised. Game state can be manipulated.

Attack Tree Path: Exploit Networking Vulnerabilities - Denial of Service via Network Flooding - Send Excessive Network Traffic

  • Attack Vector:
    • Attacker sends a large volume of network traffic to the application or server.
    • This overwhelms the network resources and application's ability to process legitimate requests.
  • Impact: Denial of Service (Application/Server) - The application becomes unavailable to legitimate users.
