Attack Tree Analysis for realm/jazzy

Objective: To leak sensitive information (source code structure, internal API documentation, potentially private code snippets if misconfigured) from an application using Jazzy.

Attack Tree Path: 1. Information Leakage

  • 1.1 Insecure Configuration [HIGH-RISK]: This is the primary attack vector, focusing on misconfigurations of Jazzy that can lead to unintended information disclosure.

    • Likelihood: High. This encompasses common mistakes made during Jazzy setup and usage.

    • Impact: High to Very High. The severity depends on the specific information leaked, ranging from internal API details to complete source code exposure.

    • Effort: Very Low to Low. Exploiting these misconfigurations typically requires minimal effort.

    • Skill Level: Novice to Intermediate. Basic understanding of Jazzy and web server configurations is sufficient.

    • Detection Difficulty: Medium. Requires reviewing Jazzy configurations and the generated output, as well as web server configurations.

    • 1.1.1 min_acl Too Permissive [CRITICAL]: This specific misconfiguration involves setting the --min_acl option to a value that exposes more information than intended (e.g., internal or private).

      • Likelihood: High. This is a very common mistake, often due to a lack of understanding of the --min_acl option or a failure to properly review the generated documentation.
      • Impact: High to Very High. Exposing internal APIs and implementation details significantly increases the attack surface of the application. Exposing private code snippets is a critical security breach.
      • Effort: Very Low. The attacker simply needs to access the generated documentation, which is often publicly available.
      • Skill Level: Novice. No special skills are required.
      • Detection Difficulty: Medium. Requires reviewing the Jazzy configuration and the generated documentation. Automated tools can help, but manual inspection is often necessary.

    • 1.1.2 Exposing source_directory Contents [CRITICAL]: This vulnerability occurs when the directory containing the source code (specified by source_directory in Jazzy's configuration) is accidentally made accessible via the web server.

      • Likelihood: Medium. This requires a misconfiguration of the web server or a deployment error. It's less likely than a direct Jazzy misconfiguration but still a significant risk.
      • Impact: Very High. Direct access to the source code represents a complete compromise of the application's intellectual property and allows attackers to analyze the code for vulnerabilities at their leisure.
      • Effort: Low to Medium. The effort depends on the specific misconfiguration. It could be as simple as forgetting to set proper directory permissions or a more complex web server configuration error.
      • Skill Level: Novice to Intermediate. Basic web server administration knowledge is required.
      • Detection Difficulty: Easy to Medium. Can be detected through regular security audits, penetration testing, or by monitoring web server logs for unusual access patterns (requests to files within the source directory).
