Attack Surface Analysis for roots/sage

Attack Surface: Vulnerable Node.js Dependencies

  • Description: Sage relies on Node.js and npm/Yarn, introducing a dependency chain. Vulnerabilities in these dependencies used in Sage's build process can be exploited.
  • Sage Contribution: Sage's package.json defines numerous dependencies required for development and build processes. Outdated or vulnerable packages here directly affect the application's security posture due to Sage's tooling.
  • Example: A vulnerability is discovered in a Webpack loader used by Sage's build process. An attacker could craft a malicious file that, when processed during the build, executes arbitrary code on the developer's machine or build server.
  • Impact: Supply chain attacks, arbitrary code execution, compromised build process, potential for backdoored builds.
  • Risk Severity: High
  • Mitigation Strategies:
    • Regularly audit and update Node.js dependencies using npm audit or yarn audit.
    • Implement automated dependency scanning in CI/CD pipelines to detect vulnerabilities early.
    • Use dependency lock files (package-lock.json, yarn.lock) to ensure consistent dependency versions.
    • Subscribe to security advisories for Node.js and key dependencies used by Sage.

Attack Surface: Template Injection via Blade Misuse

  • Description: While Blade templating engine is designed to be safer than raw PHP, improper use within Sage themes can still lead to template injection vulnerabilities.
  • Sage Contribution: Sage mandates the use of Blade as its templating engine. Developers working with Sage must use Blade, and misuse within Blade templates is a direct consequence of using Sage's chosen templating system.
  • Example: A developer uses user-supplied data directly within a @php directive in a Blade template within a Sage theme without proper sanitization. An attacker could inject malicious PHP code through user input, leading to remote code execution.
  • Impact: Remote code execution, information disclosure, cross-site scripting (XSS).
  • Risk Severity: High
  • Mitigation Strategies:
    • Always sanitize and validate user input before using it in Blade templates within Sage themes.
    • Adhere to secure coding practices for Blade templating, utilizing Blade's escaping mechanisms.
    • Avoid using @php directives for complex logic in Blade templates and favor Blade components and controllers for better security and structure within Sage themes.
    • Conduct code reviews specifically looking for potential template injection vulnerabilities in Blade templates within Sage themes.

Attack Surface: Exposure of Configuration Files

  • Description: Configuration files, especially .env files commonly used in Sage projects for environment variables, can contain sensitive information. Accidental public exposure of these files is a critical risk.
  • Sage Contribution: Sage projects often utilize .env files (or similar mechanisms) for environment configuration as part of its modern development approach. Incorrect deployment practices in Sage projects can lead to these files being publicly accessible.
  • Example: A developer deploys a Sage theme and forgets to exclude the .env file from the web server's public directory. An attacker accesses the .env file directly via a web request and obtains database credentials, API keys, or other secrets used by the Sage-based application.
  • Impact: Information disclosure of sensitive data, potential compromise of databases, external services, and the application itself.
  • Risk Severity: Critical
  • Mitigation Strategies:
    • Ensure proper .gitignore configuration in Sage projects to exclude sensitive files like .env from version control and deployments.
    • Configure web servers hosting Sage applications to prevent direct access to configuration files and directories (e.g., using .htaccess or server block configurations).
    • Store sensitive information securely using environment variables and secure vault solutions instead of directly in configuration files whenever possible in Sage projects.
