界: Encapsulation

カプセル化とは、強い境界線を引くことです。Web ブラウザの場合は、自分のモバイルコードが他のモバイルコードに悪用されないようにすることを意味します。サーバー上では、検証されたデータと検証されていないデータ、あるユーザーのデータと別のユーザーのデータ、またはユーザーが見ることを許可されたデータと許可されていないデータの区別などを意味する場合があります。

Insecure IPC: Missing URL Validation

Objective-C
Swift

Abstract

アプリケーションは、URL ベースのプロシージャ間通信 (IPC) コールで、コール URL の検証に失敗します。

Explanation

サードパーティアプリケーションまたは webview が URL を使用してアプリケーションと通信する際、受信側のアプリケーションはさらに操作を進める前に、コール URL を検証する必要があります。受信側のアプリケーションは、UIApplicationDelegate application:didFinishLaunchingWithOptions: または　UIApplicationDelegate application:willFinishLaunchingWithOptions: 委任メソッドを使用してコール URL を開くことを検証することもできます。

例 1: 次の UIApplicationDelegate application:didFinishLaunchingWithOptions: 委任メソッドの実装ではコール URL の検証に失敗し、常に信頼できない URL を処理します。


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