Attack Tree Analysis for jverkoey/nimbus

Objective: Compromise application using Nimbus vulnerabilities.

Attack Tree Visualization

        • (AND)─ Inject Payload into Application [CRITICAL NODE - Injection Point]
          • (OR)─ User-Controlled Input Fields [HIGH-RISK PATH START]
            • └─── Input malicious script into forms, search bars, etc.
          • (OR)─ URL Parameters [HIGH-RISK PATH START]
            • └─── Inject script via URL parameters processed by Nimbus
          • (AND)─ Payload Execution [CRITICAL NODE - Execution]
            • └─── User interacts with Nimbus-rendered content, triggering XSS
          • (THEN)─ Achieve XSS Impact [CRITICAL NODE - XSS Impact]
            • (OR)─ Steal Session Cookies/Tokens [HIGH-RISK PATH END - HIGH IMPACT]
              • └─── Use JavaScript to access and exfiltrate cookies
            • (OR)─ Deface Application UI [HIGH-RISK PATH END - MEDIUM IMPACT]
              • └─── Modify DOM to alter application appearance
            • (OR)─ Redirect User to Malicious Site [HIGH-RISK PATH END - MEDIUM/HIGH IMPACT]
              • └─── Use JavaScript to redirect user to attacker-controlled domain
            • (OR)─ Execute Further Actions on Behalf of User [HIGH-RISK PATH END - HIGH IMPACT]
              • └─── Perform actions within the application as the compromised user
            • (OR)─ Keylogging/Data Exfiltration [HIGH-RISK PATH END - HIGH IMPACT]
              • └─── Capture user input or sensitive data displayed by Nimbus
    • (OR)─ Exploit Misuse of Nimbus by Developers [CRITICAL NODE - Misuse by Developers]
      • (OR)─ Insecure Integration with Nimbus [CRITICAL NODE - Insecure Integration]
        • (AND)─ Identify Insecure Nimbus Usage Patterns [CRITICAL NODE - Insecure Usage Patterns]
          • (OR)─ Improper Input Sanitization Before Nimbus Rendering [HIGH-RISK PATH START]
            • └─── Application fails to sanitize user input before passing it to Nimbus for rendering
          • (OR)─ Exposing Sensitive Data in Nimbus-Rendered UI [HIGH-RISK PATH START]
            • └─── Application unintentionally displays sensitive information via Nimbus components
          • (THEN)─ Achieve Impact of Misuse [CRITICAL NODE - Impact of Misuse] (Often leads to XSS, Information Disclosure, etc.)
            • └─── (Impacts are similar to those listed under "Exploit Nimbus Client-Side Vulnerabilities") [HIGH-RISK PATH END - HIGH IMPACT - XSS, Information Disclosure etc.]

Attack Tree Path: High-Risk Path 1: XSS via User-Controlled Input Fields

  • Attack Vector: An attacker injects malicious JavaScript code into user-controlled input fields (e.g., forms, search bars) within the application.
  • Critical Nodes Involved:
    • Compromise Application Using Nimbus (Root Goal)
    • Exploit Nimbus Client-Side Vulnerabilities
    • Cross-Site Scripting (XSS) via Nimbus
    • Inject Payload into Application (User-Controlled Input Fields)
    • Payload Execution
    • Achieve XSS Impact
  • Impact: If successful, the attacker can execute arbitrary JavaScript code in the user's browser when they interact with content rendered by Nimbus. This can lead to session hijacking (stealing cookies/tokens), UI defacement, redirection to malicious sites, performing actions on behalf of the user, or data exfiltration.

Attack Tree Path: High-Risk Path 2: XSS via URL Parameters

  • Attack Vector: An attacker crafts a malicious URL containing JavaScript code within URL parameters that are processed and rendered by Nimbus.
  • Critical Nodes Involved:
    • Compromise Application Using Nimbus (Root Goal)
    • Exploit Nimbus Client-Side Vulnerabilities
    • Cross-Site Scripting (XSS) via Nimbus
    • Inject Payload into Application (URL Parameters)
    • Payload Execution
    • Achieve XSS Impact
  • Impact: Similar to XSS via user-controlled input, successful exploitation allows arbitrary JavaScript execution, leading to session hijacking, UI defacement, redirection, actions on behalf of the user, or data exfiltration.

Attack Tree Path: High-Risk Path 3: Misuse - Improper Input Sanitization Before Nimbus Rendering

  • Attack Vector: Developers fail to properly sanitize user-provided data before passing it to Nimbus for rendering. If Nimbus itself has vulnerabilities in handling unsanitized input, or if the application logic around Nimbus is flawed, this can lead to XSS.
  • Critical Nodes Involved:
    • Compromise Application Using Nimbus (Root Goal)
    • Exploit Misuse of Nimbus by Developers
    • Insecure Integration with Nimbus
    • Identify Insecure Nimbus Usage Patterns
    • Improper Input Sanitization Before Nimbus Rendering
    • Achieve Impact of Misuse
  • Impact: This misuse often results in XSS vulnerabilities. The impact is the same as described in High-Risk Path 1 and 2, including session hijacking, UI defacement, redirection, actions on behalf of the user, or data exfiltration.

Attack Tree Path: High-Risk Path 4: Misuse - Exposing Sensitive Data in Nimbus-Rendered UI

  • Attack Vector: Developers unintentionally use Nimbus to display sensitive information in the application's user interface without proper access controls or masking.
  • Critical Nodes Involved:
    • Compromise Application Using Nimbus (Root Goal)
    • Exploit Misuse of Nimbus by Developers
    • Insecure Integration with Nimbus
    • Identify Insecure Nimbus Usage Patterns
    • Exposing Sensitive Data in Nimbus-Rendered UI
    • Achieve Impact of Misuse
  • Impact: This leads to information disclosure. Attackers or unauthorized users can gain access to sensitive data that should not be exposed in the client-side UI, potentially leading to privacy violations, data breaches, or further attacks based on the revealed information.
