Attack Tree Analysis for allinurl/goaccess

Objective: Gain Unauthorized Access to Sensitive Information OR Disrupt Reporting/Monitoring

Attack Tree Visualization

                                  Attacker's Goal:
                                  Gain Unauthorized Access to Sensitive Information
                                  /

  • = High-Risk Path [CRITICAL NODE] = Critical Node Numbers (1, 2, 3) represent individual attack steps within a node.

Attack Tree Path: Sub-Goal 1: Information Disclosure [CRITICAL NODE]

  • Description: This is the primary and most critical area of concern. GoAccess's main function is to provide information, making unauthorized access to that information the most likely and impactful attack vector.
    • Overall Likelihood: High
    • Overall Impact: High to Very High
    • Overall Effort: Low to Medium
    • Overall Skill Level: Beginner to Intermediate
    • Overall Detection Difficulty: Varies (Easy to Hard)

Attack Tree Path: A1: Exploit GoAccess Output Vulnerabilities (HTML/JSON Report) - HIGH-RISK PATH

  • Description: Attackers target the generated reports (HTML, JSON, CSV) that GoAccess creates. If these reports are stored insecurely, they can be directly accessed. * Attack Steps: 1. Identify the location of GoAccess output files: * Likelihood: Medium to High * Impact: Medium to High * Effort: Very Low to Low * Skill Level: Beginner * Detection Difficulty: Easy to Medium 2. Attempt to access the report files directly: * Likelihood: High * Impact: Medium to High * Effort: Very Low * Skill Level: Beginner * Detection Difficulty: Easy 3. Analyze the report for sensitive information: * Likelihood: High * Impact: Medium to High * Effort: Low * Skill Level: Beginner * Detection Difficulty: Hard * Mitigations: * Store reports outside the web root. * Implement strong authentication and authorization for report access. * Regularly review report contents for sensitive data. * Avoid predictable report file paths. * Consider encrypting reports at rest.

Attack Tree Path: A2: Leverage GoAccess Real-Time HTML Output (WebSocket) - HIGH-RISK PATH

  • Description: Attackers target the real-time data stream provided by GoAccess via WebSockets. If the WebSocket connection is not secured, the data can be intercepted. * Attack Steps: 1. Identify the WebSocket endpoint: * Likelihood: Medium * Impact: Medium to High * Effort: Low to Medium * Skill Level: Intermediate * Detection Difficulty: Medium 2. Attempt to connect to the WebSocket without authentication: * Likelihood: High * Impact: Medium to High * Effort: Low * Skill Level: Intermediate * Detection Difficulty: Medium 3. Capture the real-time data stream: * Likelihood: High * Impact: Medium to High * Effort: Low * Skill Level: Intermediate * Detection Difficulty: Hard * Mitigations: * Use Secure WebSockets (wss://). This is crucial. * Implement authentication for the WebSocket connection (handled at the web server or application level). * Validate the Origin header in the WebSocket handshake. * Implement rate limiting on WebSocket connections.
