Attack Tree Path: Sub-Goal: Inject False Device Data (CRITICAL NODE)

  • Tactic: Header Injection (User-Agent) (HIGH-RISK)
    • Description: The attacker modifies the User-Agent HTTP header to misrepresent the user's device, operating system, or browser. This is the most common and easily exploited attack vector.
    • Attack Vectors:
      • [A1] Spoof Mobile Device:
        • Likelihood: Very High
        • Impact: Medium to High
        • Effort: Very Low
        • Skill Level: Very Low
        • Detection Difficulty: Medium
        • Description: The attacker sets the User-Agent to a string representing a common mobile device. This can trick the application into serving mobile-specific content, bypassing desktop-only security checks, or triggering other mobile-specific behavior.
      • [A2] Spoof Desktop Device:
        • Likelihood: Very High
        • Impact: Medium to High
        • Effort: Very Low
        • Skill Level: Very Low
        • Detection Difficulty: Medium
        • Description: The attacker sets the User-Agent to a string representing a common desktop browser. This can bypass mobile-specific security features or trigger desktop-specific logic that may be less secure.
      • [A3] Spoof Specific OS/Version:
        • Likelihood: High
        • Impact: Medium to High
        • Effort: Low
        • Skill Level: Low
        • Detection Difficulty: Medium to High
        • Description: The attacker sets the User-Agent to target a specific operating system or version. This could be used to exploit known vulnerabilities in that specific version or to trigger application logic that behaves differently for certain OS/version combinations.

Attack Tree Path: Sub-Goal: Exploit Logic Flaws in Application's Use of mobile-detect (CRITICAL NODE)

  • Tactic: Exploit OS Detection Logic Flaws (HIGH-RISK)

    • Description: The attacker leverages vulnerabilities in how the application uses the OS information provided by mobile-detect. The vulnerability is in the application's code, not the library itself.
    • Attack Vectors:
      • [B1] Spoof Specific OS:
        • Likelihood: High
        • Impact: Medium to High
        • Effort: Low
        • Skill Level: Low
        • Detection Difficulty: Medium to High
        • Description: The attacker spoofs a specific operating system (often via the User-Agent) to trigger OS-specific behavior within the application. This could be used to access features or content intended only for that OS.
      • [B2] Bypass OS-Specific Security:
        • Likelihood: Medium
        • Impact: High
        • Effort: Low
        • Skill Level: Low
        • Detection Difficulty: High
        • Description: If the application has weaker security measures for certain operating systems, the attacker can spoof that OS to bypass those security controls.

  • Tactic: Exploit Browser Detection Logic Flaws (HIGH-RISK)

    • Description: Similar to OS detection flaws, this involves exploiting vulnerabilities in how the application uses the browser information from mobile-detect.
    • Attack Vectors:
      • [B4] Spoof Specific Browser:
        • Likelihood: High
        • Impact: Medium to High
        • Effort: Low
        • Skill Level: Low
        • Detection Difficulty: Medium to High
        • Description: The attacker spoofs a specific browser (usually via the User-Agent) to trigger browser-specific behavior in the application.
      • [B5] Bypass Browser-Specific Security:
        • Likelihood: Medium
        • Impact: High
        • Effort: Low
        • Skill Level: Low
        • Detection Difficulty: High
        • Description: If the application has different security measures for different browsers, the attacker can spoof a browser with weaker security to bypass controls.

  • Tactic: Exploit Version Detection Logic Flaws (HIGH-RISK)

    • Description: This involves exploiting how application uses version of the browser.
    • Attack Vectors:
      • [A8] Spoof Older Version:
        • Likelihood: High
        • Impact: Medium to High
        • Effort: Low
        • Skill Level: Low
        • Detection Difficulty: Medium to High
        • Description: The attacker spoofs an older version to trigger fallback behavior or exploit known vulnerabilities in that older version's handling.
      • [A9] Bypass Security Checks:
        • Likelihood: High
        • Impact: High
        • Effort: Low
        • Skill Level: Low
        • Detection Difficulty: Medium to High
        • Description: The older version logic might have weaker security.

  • Tactic: Exploit Browser Detection Logic Flaws (HIGH-RISK) - Continued

    • Description: Further attacks exploiting browser detection.
    • Attack Vectors:
      • [B7] Spoof bot to bypass bot protection:
        • Likelihood: Medium
        • Impact: High
        • Effort: Low
        • Skill Level: Low
        • Detection Difficulty: High
        • Description: If the application uses mobile-detect to identify bots, the attacker could spoof a legitimate user-agent.
      • [B8] Spoof less common browser:
        • Likelihood: Medium
        • Impact: High
        • Effort: Low
        • Skill Level: Low
        • Detection Difficulty: High
        • Description: Bypass security checks that are only implemented for common browsers.
      • [B9] Bypass CSRF protection:
        • Likelihood: Low
        • Impact: High
        • Effort: Low
        • Skill Level: Low
        • Detection Difficulty: High
        • Description: If CSRF protection is implemented only for specific browsers.
      • [B10] Bypass Content Security Policy:
        • Likelihood: Low
        • Impact: High
        • Effort: Low
        • Skill Level: Low
        • Detection Difficulty: High
        • Description: If CSP is implemented only for specific browsers.
      • [B11] Bypass XSS protection:
        • Likelihood: Low
        • Impact: High
        • Effort: Low
        • Skill Level: Low
        • Detection Difficulty: High
        • Description: If XSS protection is implemented only for specific browsers.
