This entire path is considered high-risk due to the inherent dangers of executing JavaScript on the server, a core feature of SSR.

  • Node.js Vulnerabilities in ExecJS Context {CRITICAL}

    • Attack Vector: Exploiting vulnerabilities within the Node.js runtime environment used by ExecJS for server-side rendering.
    • Details:
      • Attackers leverage known vulnerabilities in specific Node.js versions.
      • These vulnerabilities can allow for arbitrary code execution on the server.
      • Often, exploits are publicly available, making this a low-effort attack.
    • Specific Attack:
      • Outdated Node.js Version {CRITICAL}:
        • Description: The application uses an outdated Node.js version with known security vulnerabilities.
        • Impact: Complete server compromise, allowing the attacker to execute arbitrary code, access sensitive data, and potentially pivot to other systems.
        • Mitigation: Crucially, keep the Node.js version up-to-date. Use a version manager (nvm, asdf) and regularly check for security updates. Use dependency checkers (npm audit, yarn audit).
  • React Component Injection [HIGH RISK]

    • Attack Vector: Injecting malicious code into React components during the server-side rendering process.
    • Details:
      • Attackers manipulate input data to inject malicious JavaScript.
      • If this data is not properly sanitized before being used in SSR, the injected code will execute on the server.
    • Specific Attack:
      • XSS via Server-Rendered Content {CRITICAL}:
        • Description: User-supplied data is not properly sanitized before being passed to React components for server-side rendering, allowing for the injection of malicious JavaScript.
        • Impact: Server-side code execution, leading to potential data exfiltration, server compromise, and further attacks.
        • Mitigation: Strictly sanitize all user-supplied data before it is used in server-side rendering. Use a robust HTML sanitization library (like DOMPurify on the server, if possible, or a Rails-specific sanitization helper). Never trust user input. Consider a Content Security Policy (CSP). Sanitize before data hits the React component on the server.
  • Specific Attack:
    • Leaked API Keys in Config Files {CRITICAL}:
      • Description: Sensitive API keys or other credentials are hardcoded in react_on_rails configuration files, which are then accidentally exposed (e.g., committed to a public repository).
      • Impact: Direct access to the services protected by those API keys, potentially leading to data breaches, financial loss, and reputational damage.
      • Mitigation: Never hardcode sensitive credentials in configuration files. Use environment variables. Use a gem like dotenv-rails in development. In production, use your hosting provider's mechanism for setting environment variables (Heroku config vars, AWS Parameter Store, etc.).
