Attack Tree Path: Compromise Application Using Swiper [CRITICAL NODE]

  • This is the root goal of the attacker. Success at any of the sub-nodes leads to achieving this goal.

Attack Tree Path: Exploit Client-Side Vulnerabilities in Swiper Usage [CRITICAL NODE] [HIGH RISK PATH]

  • This path focuses on directly exploiting weaknesses in how the application uses the Swiper library on the client-side.
  • Attack Vectors:
    • Cross-Site Scripting (XSS) via Swiper
    • Client-Side Denial of Service (DoS) via Swiper
    • Client-Side Logic Manipulation via Swiper API Abuse

Attack Tree Path: Cross-Site Scripting (XSS) via Swiper [CRITICAL NODE] [HIGH RISK PATH]

  • This is the most critical threat vector. Attackers aim to inject and execute malicious JavaScript code in the user's browser through Swiper.
  • Attack Vectors:
    • Configuration Injection XSS
    • Slide Content Injection XSS
    • Vulnerability in Swiper Library Code (Less Likely, but Possible)

Attack Tree Path: Configuration Injection XSS [CRITICAL NODE] [HIGH RISK PATH]

  • How it works: Attackers manipulate Swiper configuration options, especially if the application dynamically generates configuration based on user input without sanitization. Malicious JavaScript injected into configuration options (like onSlideChange, renderSlide) executes in the user's browser.
  • Example: Application sets onSlideChange based on a URL parameter: swiper.on('slideChange', function() { eval(getParameterByName('callback')); });. Attacker crafts URL like example.com/?callback=alert('XSS').
  • Mitigation:
    • Never use eval() or similar unsafe functions for dynamic configuration.
    • Strictly sanitize and validate user-provided data in Swiper configuration.
    • Use Content Security Policy (CSP) to restrict script sources and inline execution.

Attack Tree Path: Slide Content Injection XSS [CRITICAL NODE] [HIGH RISK PATH]

  • How it works: Attackers inject malicious HTML/JavaScript into content displayed within Swiper slides. This is possible if the application renders user-supplied or external data within Swiper slides without proper sanitization. Malicious script executes when Swiper renders the slide.
  • Example: Slide content fetched from a database and displayed directly in Swiper slides without HTML encoding. Attacker injects <img src=x onerror=alert('XSS')> into the database.
  • Mitigation:
    • Always sanitize and encode user-provided or external data before displaying in Swiper slides. Use HTML encoding.
    • Use a templating engine that automatically escapes HTML.
    • Implement CSP for further XSS mitigation.

Attack Tree Path: Exploit Server-Side Vulnerabilities Related to Swiper Integration (Indirect) [CRITICAL NODE]

  • This path focuses on exploiting server-side vulnerabilities that indirectly impact the client-side Swiper implementation, leading to client-side attacks.
  • Attack Vectors:
    • Server-Side Configuration Injection leading to Client-Side Exploitation
    • Server-Side Data Manipulation affecting Swiper Content

Attack Tree Path: Server-Side Configuration Injection leading to Client-Side Exploitation [HIGH RISK PATH]

  • How it works: Attackers exploit server-side vulnerabilities (e.g., injection flaws) to influence Swiper configuration generated by the server. This malicious configuration is then sent to the client and exploited, often leading to XSS.
  • Example: Server-side script generates Swiper configuration based on data from a SQL injection vulnerable database. Attacker injects malicious SQL to modify configuration data, leading to XSS on the client.
  • Mitigation:
    • Secure server-side applications against common web vulnerabilities (SQL injection, command injection, etc.).
    • Sanitize and validate data from backend systems before using it to generate Swiper configuration.
    • Treat server-generated Swiper configuration as potentially untrusted and apply client-side sanitization if needed.
