계: Encapsulation

캡슐화는 강력한 경계를 그리는 것입니다. 웹 브라우저에서는 사용자의 모바일 코드가 다른 모바일 코드에 의해 오용되지 않도록 하는 것을 의미합니다. 서버에서는 검증된 데이터와 검증되지 않은 데이터, 한 사용자의 데이터와 다른 사용자의 데이터, 데이터 사용자가 볼 수 있는 데이터와 볼 수 없는 데이터 간의 차별화를 의미할 수 있습니다.

Insecure IPC: Missing URL Validation

Objective-C
Swift

Abstract

응용 프로그램이 URL 기반 IPC(Inter-Procedure Communication) 호출에서 URL 호출의 확인에 실패합니다.

Explanation

타사 응용 프로그램 또는 webview가 귀하의 응용 프로그램과 통신하기 위해 URL을 사용할 때 수신 응용 프로그램은 추가 작업을 계속하기 전에 호출 URL을 확인해야 합니다. 수신 응용 프로그램은 UIApplicationDelegate application:didFinishLaunchingWithOptions: 또는 UIApplicationDelegate application:willFinishLaunchingWithOptions: 대리자 메서드를 사용하여 호출 URL을 열고자 한다는 것을 확인할 수 있습니다.

예제 1: 다음의 UIApplicationDelegate application:didFinishLaunchingWithOptions: 대리자 메서드 구현은 호출 URL의 확인에 실패하고 항상 신뢰할 수 없는 URL을 처리합니다.


    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NS Dictionary *)launchOptions {
        return YES;
    }
