Threat Model Analysis for higherorderco/bend

Threat: Schema Injection

  • Description: Attacker injects malicious schema definitions through dynamic configuration or extension points in Bend. They could modify the data model to bypass security checks, gain broader access, or disrupt application functionality. This is directly related to how Bend handles data model configuration and potential extensibility features.
    • Impact: Unauthorized access, privilege escalation, data corruption, denial of service, application instability.
    • Bend Component Affected: Data Model Configuration, Plugin System (if applicable)
    • Risk Severity: Critical
    • Mitigation Strategies:
      • Avoid dynamic schema modifications based on user input if possible.
      • If dynamic schema modifications are necessary, strictly validate and sanitize all input used for schema definition.
      • Implement strong input validation and sanitization for configuration files or plugin inputs.
      • Regularly audit and review schema configurations for unexpected changes.

Threat: Mass Assignment Vulnerability

  • Description: Attacker sends malicious API requests with extra parameters to modify data attributes they are not authorized to change. They leverage automatically generated API endpoints by Bend that directly map request parameters to data model attributes without proper filtering. This is a direct consequence of Bend's API generation approach.
    • Impact: Data manipulation, privilege escalation, unauthorized modification of sensitive attributes.
    • Bend Component Affected: API Generation, Request Handling
    • Risk Severity: High
    • Mitigation Strategies:
      • Disable or restrict mass assignment globally if possible within Bend's configuration.
      • Implement attribute whitelisting for API endpoints within Bend's data model definition or API configuration to explicitly define allowed modifiable attributes.
      • Utilize Bend's features (if available) to control data binding and validation.
      • Thoroughly validate and sanitize all user inputs before data binding, even when using Bend's generated APIs.

Threat: Insufficient Input Validation in APIs (Bend Generated)

  • Description: Attacker exploits lack of input validation in Bend-generated APIs to inject malicious payloads. This could lead to XSS, SQL Injection (if Bend directly constructs queries), or other injection attacks due to weaknesses in Bend's API generation or default settings.
    • Impact: Cross-Site Scripting (XSS), SQL Injection, data breaches, code execution, denial of service.
    • Bend Component Affected: API Generation, Input Handling (within generated APIs)
    • Risk Severity: Critical
    • Mitigation Strategies:
      • Configure Bend to enforce robust input validation and sanitization for all generated API endpoints.
      • Ensure Bend uses parameterized queries or ORM features by default to prevent SQL Injection in generated code.
      • If Bend allows customization of generated API handlers, implement input validation and output encoding within those customizations.
      • Review and test generated APIs for input validation weaknesses.

Threat: Insecure Default API Configurations (Bend Defaults)

  • Description: Attacker exploits insecure default configurations of Bend-generated APIs, such as publicly exposed administrative endpoints or weak authentication provided by Bend by default. They can gain unauthorized access to sensitive functionalities or data due to Bend's initial setup.
    • Impact: Unauthorized access, privilege escalation, data breaches, system compromise.
    • Bend Component Affected: API Generation, Default Configuration, Setup Process
    • Risk Severity: High
    • Mitigation Strategies:
      • Review and harden default API configurations provided by Bend before deployment.
      • Ensure all sensitive endpoints generated by Bend require authentication and authorization.
      • Disable or restrict access to debugging or administrative endpoints generated by Bend in production.
      • Consult Bend's documentation for security hardening guidelines specific to its default configurations.

Threat: Weak Default Authentication/Authorization (Bend Provided)

  • Description: Attacker exploits weak or insecure default authentication/authorization mechanisms provided directly by Bend. This could involve weak algorithms, insecure storage, or bypassable implementations inherent in Bend's built-in security features.
    • Impact: Unauthorized access, account compromise, privilege escalation, data breaches.
    • Bend Component Affected: Authentication Module (Bend's built-in), Authorization Module (Bend's built-in)
    • Risk Severity: Critical
    • Mitigation Strategies:
      • Avoid using Bend's default authentication/authorization mechanisms if they are weak or insufficient for your security requirements.
      • If using Bend's built-in features, configure them to use strong authentication methods and algorithms.
      • Ensure Bend's default credential storage (if any) is secure and meets security best practices.
      • Implement robust authorization checks and role-based access control using Bend's authorization features, ensuring they are correctly configured and enforced.

Threat: Vulnerabilities in Code Generation Logic (Bend's Engine)

  • Description: Flaws in Bend's code generation logic itself lead to insecure code being generated. This could introduce vulnerabilities like SQL Injection, XSS, or other code-level flaws in the application due to errors in Bend's core functionality.
    • Impact: Code injection vulnerabilities, data breaches, application compromise, denial of service.
    • Bend Component Affected: Code Generation Engine, Templating Engine (if used by Bend for code generation)
    • Risk Severity: Critical
    • Mitigation Strategies:
      • Rely on the Bend framework developers to thoroughly test and audit Bend's code generation logic.
      • Stay updated with Bend framework updates and security patches that address potential flaws in code generation.
      • If possible, review the generated code for security vulnerabilities, especially if Bend allows customization or extension of code generation.
      • Report any suspected vulnerabilities in Bend's code generation logic to the Bend development team.

Threat: Template Injection in Templating Engine (If Bend Uses Unsafe Templating)

  • Description: Attacker injects malicious code into templates used by Bend if Bend's templating engine is vulnerable or used unsafely. If user input is incorporated into templates without proper sanitization within Bend's framework, it can lead to code execution.
    • Impact: Code execution, server-side template injection, application compromise, data breaches.
    • Bend Component Affected: Templating Engine (if used by Bend), Code Generation (if templates are used for code generation)
    • Risk Severity: Critical
    • Mitigation Strategies:
      • Understand if Bend uses a templating engine and its security posture.
      • If Bend uses a templating engine, ensure user input is never directly used in templates without strict sanitization within Bend's context.
      • If possible, configure Bend to use a secure templating engine and follow secure templating practices within the Bend framework.
      • Stay informed about security advisories related to the templating engine used by Bend.

Threat: Insecure Default Configurations of Bend Framework (Framework Defaults)

  • Description: Bend itself might have insecure default configurations that are applied when setting up a new project. These defaults, inherent to the framework, could include exposed ports, weak credentials, or insecure settings that are not immediately obvious to developers using Bend.
    • Impact: Unauthorized access, system compromise, data breaches, easy exploitation of default weaknesses present in Bend's initial setup.
    • Bend Component Affected: Default Configuration (within Bend framework), Setup Process (Bend's project initialization)
    • Risk Severity: High
    • Mitigation Strategies:
      • Review and harden default configurations provided by Bend immediately after setting up a new Bend project.
      • Change any default credentials set by Bend for administrative accounts or services.
      • Disable or restrict access to unnecessary services or ports exposed by Bend's default configuration.
      • Consult Bend's documentation for security hardening guides specific to its default framework settings.
