Attack Tree Path: 1.1.1.1 Inject Fake Scroll Events via JavaScript [CRITICAL]

  • Description: The attacker uses JavaScript to simulate scroll events, triggering MJRefresh's refresh logic repeatedly. This can be done even if the user is not actually scrolling.
  • Likelihood: High
  • Impact: Medium (Application slowdown/unresponsiveness)
  • Effort: Low
  • Skill Level: Novice
  • Detection Difficulty: Medium (Requires monitoring of network requests and application performance)
  • Mitigation:
    • Implement client-side rate limiting on scroll event handling.
    • Use debouncing or throttling to limit the frequency of refresh triggers.
    • Implement server-side rate limiting to protect the backend.

Attack Tree Path: 1.1.2.1 Call methods directly from developer console or injected script. [CRITICAL]

  • Description: The attacker directly calls MJRefresh's beginRefreshing (or similar) method repeatedly, either through the browser's developer console or by injecting a script into the page.
  • Likelihood: High
  • Impact: Medium (Application slowdown/unresponsiveness)
  • Effort: Low
  • Skill Level: Novice
  • Detection Difficulty: Medium (Requires monitoring of network requests and application performance)
  • Mitigation:
    • Implement client-side rate limiting on calls to MJRefresh's methods.
    • Implement server-side rate limiting to protect the backend.
    • Consider obfuscating or minimizing the application code to make it slightly harder to interact with directly.

Attack Tree Path: 2.2.1.1 If the application doesn't properly protect the callback function, replace it with a function that redirects the user. [CRITICAL]

  • Description: The attacker overwrites the callback function provided to MJRefresh with their own function. This malicious function redirects the user to a different website, potentially a phishing site.
  • Likelihood: Low to Medium (Depends on application's security practices)
  • Impact: High (User redirected to malicious site, potential credential theft)
  • Effort: Low
  • Skill Level: Intermediate
  • Detection Difficulty: Medium (Requires monitoring of network traffic and application behavior)
  • Mitigation:
    • Store callback functions in a secure way (e.g., within a closure) to prevent them from being easily overwritten.
    • Avoid using global variables for callbacks.
    • Use a well-defined API for interacting with MJRefresh, rather than exposing internal functions directly.

Attack Tree Path: 3.1.1.1 If MJRefresh passes unsanitized data to the callback, and the callback renders this data into the DOM, inject a <script> tag. [CRITICAL]

  • Description: The attacker exploits an XSS vulnerability. If MJRefresh passes data to the callback function, and that data is then rendered into the DOM without proper sanitization, the attacker can inject a <script> tag containing malicious JavaScript code.
  • Likelihood: Low (Requires MJRefresh and the application to be vulnerable to XSS)
  • Impact: Very High (Arbitrary code execution, complete application compromise)
  • Effort: Medium
  • Skill Level: Advanced
  • Detection Difficulty: Hard (Requires careful code review and security testing)
  • Mitigation:
    • Strict Input Sanitization: Never trust data passed to or from MJRefresh. Sanitize all data before rendering it in the DOM, especially within callback functions. Use a well-vetted sanitization library (like DOMPurify).
    • Content Security Policy (CSP): Implement a strong CSP to mitigate the impact of XSS vulnerabilities.
    • Output Encoding: Ensure that any data rendered into the DOM is properly encoded for the context (e.g., HTML encoding, attribute encoding).
