Attack Tree Analysis for moment/moment

Objective: Attacker's Goal: To compromise the application by exploiting vulnerabilities in Moment.js leading to:

  • Denial of Service (DoS): Making the application unavailable or significantly slower.
  • Information Disclosure: Gaining access to sensitive data processed or displayed by the application through Moment.js.
  • Logic Manipulation: Altering the application's intended behavior by manipulating date/time calculations or interpretations performed by Moment.js.

Attack Goal: Compromise Application via Moment.js Vulnerabilities [CRITICAL NODE] ├───[AND] Exploit Vulnerabilities in Moment.js Functionality [CRITICAL NODE] │ ├───[OR] Exploit Parsing Vulnerabilities [CRITICAL NODE] │ │ ├───[AND] ReDoS (Regular Expression Denial of Service) in Parsing [HIGH-RISK PATH] │ └───[OR] Exploit API Misuse in Application Code [CRITICAL NODE, HIGH-RISK PATH] │ ├───[AND] Unsafe Usage of Moment.js API [HIGH-RISK PATH] │ └───[AND] Reliance on Deprecated or Vulnerable Moment.js Features [HIGH-RISK PATH]

  • Attack Vector: This is a broad category encompassing all vulnerabilities within the Moment.js library itself. It's critical because any weakness here can directly impact applications using it.
  • Breakdown:
    • Focus Areas: Parsing logic, date/time calculation algorithms, locale data handling, and any other core functionality of Moment.js.
    • Exploitation Methods: Identifying and exploiting bugs, logic flaws, or security oversights in Moment.js code. This often requires deep code analysis or leveraging publicly disclosed vulnerabilities.
    • Impact: Can lead to various compromises depending on the vulnerability, including DoS, information disclosure, or logic manipulation within the application.
  • Attack Vector: Targeting weaknesses in how Moment.js parses date and time strings. Parsing is a complex process and often involves regular expressions, making it a common source of vulnerabilities.
  • Breakdown:
    • Focus Areas: Regular expressions used for parsing various date formats, handling of ambiguous or malformed date inputs, and format string processing.
    • Exploitation Methods:
      • ReDoS (Regular Expression Denial of Service): Crafting malicious input strings that cause vulnerable regular expressions in Moment.js parsing to consume excessive CPU resources, leading to DoS.
      • Incorrect Parsing: Providing subtly malformed or ambiguous date strings that are parsed incorrectly by Moment.js, leading to unexpected date/time values and flawed application logic.
    • Impact: ReDoS leads to Denial of Service. Incorrect parsing can cause logic errors, data corruption, and potentially security bypasses if application logic relies on the parsed dates.
  • Attack Vector: Specifically targeting regular expression vulnerabilities within Moment.js parsing logic to cause Denial of Service.
  • Breakdown:
    • Steps:
      • Identify Vulnerable Regex: Analyze Moment.js source code or known vulnerability databases to find regular expressions used in parsing that are susceptible to ReDoS.
      • Craft Malicious Input: Create input date strings designed to trigger exponential backtracking in the vulnerable regex. These strings often exploit patterns that cause the regex engine to explore many branches unsuccessfully.
      • Send Malicious Input: Submit these crafted date strings to application endpoints that use Moment.js for parsing (e.g., form fields, API parameters).
    • Impact: Application becomes unresponsive or extremely slow due to high CPU usage from Moment.js parsing, effectively causing Denial of Service.
  • Attack Vector: Exploiting vulnerabilities introduced by how the application developers use the Moment.js API, rather than vulnerabilities within Moment.js itself. This is critical because even a secure library can be misused insecurely.
  • Breakdown:
    • Focus Areas: Areas in the application code where Moment.js API is used for:
      • Displaying dates and times in the user interface.
      • Performing date/time calculations for business logic.
      • Handling date/time data in security-sensitive contexts.
    • Exploitation Methods:
      • Unsafe Output Handling (XSS): Directly embedding Moment.js formatted date strings into HTML without proper encoding or escaping, leading to Cross-Site Scripting (XSS) vulnerabilities.
      • Logic Errors due to Incorrect API Usage: Misusing Moment.js API functions in date/time calculations, leading to incorrect results and flawed application logic, potentially with security implications.
      • Reliance on Deprecated or Vulnerable Features: Using outdated or deprecated Moment.js features that have known vulnerabilities.
  • Attack Vector: Specifically focusing on vulnerabilities arising from insecure coding practices when using the Moment.js API.
  • Breakdown:
    • Steps:
      • Identify API Usage Points: Locate all instances in the application code where Moment.js API functions are called.
      • Analyze for Misuse: Examine each API usage point for potential security flaws, such as:
        • Lack of Output Encoding: Directly inserting Moment.js output into HTML without escaping.
        • Incorrect Parameter Handling: Passing user-controlled input directly to Moment.js API without validation.
        • Flawed Logic: Using Moment.js API in a way that introduces logical errors in date/time calculations or comparisons.
    • Impact: Can lead to Cross-Site Scripting (XSS), logic errors, data corruption, or other application-specific vulnerabilities depending on the nature of the API misuse.
  • Attack Vector: Exploiting known vulnerabilities in older versions of Moment.js or deprecated features that are still used by the application.
  • Breakdown:
    • Steps:
      • Identify Moment.js Version and Feature Usage: Determine the version of Moment.js used by the application and identify if any deprecated features are still in use.
      • Research Vulnerabilities: Check public vulnerability databases and security advisories for known vulnerabilities associated with the identified Moment.js version or deprecated features.
      • Exploit Known Vulnerabilities: If vulnerabilities are found, attempt to exploit them using publicly available exploits or by developing custom exploits.
    • Impact: The impact depends on the specific vulnerability. It could range from information disclosure to remote code execution (though less likely directly from Moment.js itself, more likely from underlying system if exploited).
