界: Input Validation and Representation

入力の検証や表現の問題は、メタキャラクター、代替エンコーディング、数値表現などによって引き起こされます。セキュリティの問題は、入力を信頼することに起因します。この問題に含まれるのは、「Buffer Overflow」、「Cross-Site Scripting」攻撃、「SQL Injection」などです。

Denial of Service

Abstract
攻撃者はプログラムをクラッシュさせる、あるいは正規ユーザーが利用できなくなるようにする可能性があります。
Explanation
攻撃者は大量のリクエストをアプリケーションに送りつけることで、正規ユーザーへのサービスを拒否させる可能性がありますが、フラッド攻撃は、ネットワークレイヤで除去できる場合があります。さらに解決が難しいのは、攻撃者が数回のリクエストでアプリケーションに過剰な負荷をかけることを可能とするバグです。このようなバグが利用されると、攻撃者はリクエストによって消費するシステムリソースの数量や、システムリソースが使用される期間を指定できるようになり、その結果、リソースが使い果たされる条件が作成されます。

例 1: 次のコードでは、現在の処理プロセスがスリープ状態になる期間をユーザーが指定できるようにしています。大きい数値を指定することで、攻撃者は無期限に処理プロセスを拘束する可能性があります。

Abstract
アプリケーションは、クライアントのリモート IP アドレスを使用して RateLimitPartition を作成します。
Explanation
クライアントの IP アドレスに基づいて RateLimitPartitions を作成すると、アプリケーションは、IP ソース アドレス スプーフィングを使用する Denial of Service 攻撃に対して脆弱になります。
例 1: 次の例では、GetTokenBucketLimiter() メソッドが、リモート IP アドレス (RemoteIpAddress) を、RateLimitPartition の作成時にパーティション キーとして使用します。

...
builder.Services.AddRateLimiter(limiterOptions => {
    limiterOptions.GlobalLimiter = PartitionedRateLimiter.Create<HttpContext, IPAddress>(context => {
        IPAddress? ip = context.Connection.RemoteIpAddress;
        return RateLimitPartition.GetTokenBucketLimiter(ip!, _ =>
            new TokenBucketRateLimiterOptions
            {
                TokenLimit = 7
            });
    });
});

Abstract
攻撃者は、プログラムをクラッシュさせたり、正当なユーザーによる利用を阻止する可能性があります。
Explanation
攻撃者は、アプリケーションをリクエストでフラッディングして、正当なユーザーへのサービスを拒否する可能性がありますが、フラッディング攻撃が拡散するのはネットワーク層です。さらに問題なのは、攻撃者が少量のリクエストを使用してアプリケーションを過負荷にするバグです。このようなバグにより、リクエストが消費するシステム リソースの量や、それらを使用する期間を攻撃者が指定できます。

例 1: 次のコードでは、ユーザーが Future 関数の実行時間を指定できます。大きな数値を指定すると、攻撃者が Future 関数を無期限に拘束する可能性があります。


  final duration = Platform.environment['DURATION'];
  Future.delayed(Duration(seconds: int.parse(duration!)), () => ...);

Abstract
攻撃者は、プログラムをクラッシュさせたり、正当なユーザーによる利用を阻止する可能性があります。
Explanation
攻撃者は、アプリケーションをリクエストでフラッディングして、正当なユーザーへのサービスを拒否する可能性がありますが、フラッディング攻撃が拡散するのはネットワーク層です。さらに問題なのは、攻撃者が少量のリクエストを使用してアプリケーションを過負荷にするバグです。このようなバグにより、リクエストが消費するシステム リソースの量や、それらを使用する期間を攻撃者が指定できます。

例 1: 信頼されていないデータでのサービス タイムアウトを設定すると、攻撃者が大きな値を設定した場合にサービスが応答しなくなります。


func test(r *http.Request) {
  ...
  i, _ := strconv.Atoi(r.FormValue("TIME"))
  runtime.KeepAlive(i)
  ...
  }

Abstract
攻撃者はプログラムをクラッシュさせる、あるいは正規ユーザーが利用できなくなるようにする可能性があります。
Explanation
攻撃者は大量のリクエストをアプリケーションに送りつけることで、正規ユーザーへのサービスを拒否させる可能性がありますが、フラッド攻撃は、ネットワークレイヤで除去できる場合があります。さらに解決が難しいのは、攻撃者が数回のリクエストでアプリケーションに過剰な負荷をかけることを可能とするバグです。このようなバグが利用されると、攻撃者はリクエストによって消費するシステムリソースの数量や、システムリソースが使用される期間を指定できるようになります。

例 1: 次のコードは、スレッドがスリープ状態になる時間をユーザーが指定することを許しています。攻撃者は大きな数を指定することで、スレッドを無期限に拘束できます。数回のリクエストで、攻撃者はアプリケーションのスレッド プールを使い果たすことができます。


  int usrSleepTime = Integer.parseInt(usrInput);
  Thread.sleep(usrSleepTime);
例 2: 以下のコードでは、文字列を zip ファイルから読み取ります。このコードでは、readLine() メソッドが使用されているため、読み取られる入力データのサイズに境界が設定されないことになります。攻撃者は、このコードを利用して、OutOfMemoryException を発生させることが可能です。また、大量のメモリを消費させて、プログラムがガベージ コレクションに多くの時間を消費させるようにしたり、後続の操作でメモリ不足を発生させたりすることが可能です。


  InputStream zipInput = zipFile.getInputStream(zipEntry);
  Reader zipReader = new InputStreamReader(zipInput);
  BufferedReader br = new BufferedReader(zipReader);
  String line = br.readLine();

Explanation
攻撃者は大量のリクエストをアプリケーションに送りつけることで、正規ユーザーへのサービスを拒否させる可能性がありますが、フラッド攻撃は、ネットワークレイヤで除去できる場合があります。さらに解決が難しいのは、攻撃者が数回のリクエストでアプリケーションに過剰な負荷をかけることを可能とするバグです。このようなバグが利用されると、攻撃者はリクエストによって消費するシステムリソースの数量や、システムリソースが使用される期間を指定できるようになります。

例 1: 次のコードは、使用されるファイル システムのサイズをユーザーが指定することを許しています。大きい数値を指定することで、攻撃者はファイル システムのリソースを枯渇させることができます。


  var fsync = requestFileSystemSync(0, userInput);
例 2: 次のコードは、ファイルに書き込みを行っています。このファイルは、ユーザー エージェントによって閉じられたと判断されるまで継続的に書き込みと再書き込みが実行されることがあるため、ファイルの内容を分析するのに必要なディスク クオータ、IO 帯域幅、およびプロセスが影響を受ける場合があります。


function oninit(fs) {
  fs.root.getFile('applog.txt', {create: false}, function(fileEntry) {
    fileEntry.createWriter(function(fileWriter) {
      fileWriter.seek(fileWriter.length);

Abstract
攻撃者は、プログラムをクラッシュさせたり、正当なユーザーによる利用を阻止する可能性があります。
Explanation
攻撃者は、アプリケーションをリクエストでフラッディングして、正当なユーザーへのサービスを拒否する可能性がありますが、ほとんどのフラッディング攻撃が拡散するのはネットワーク層です。さらに問題なのは、攻撃者が少量のリクエストを使用してアプリケーションを過負荷にする不具合です。このような不具合により、リクエストが消費するシステム リソースの量や、それらを使用する期間を攻撃者が指定できます。

例 1: 次のコードでは、ユーザーが connect 関数の接続タイムアウトの期間を指定できます。大きな数値を指定すると、攻撃者が connect 関数を無期限に拘束する可能性があります。


...
insecure_config_ssl_connection_timeout = {
  'user': username,
  'password': retrievedPassword,
  'host': databaseHost,
  'port': "3306",
  'connection_timeout': connection_timeout
}

mysql.connector.connect(**insecure_config_ssl_connection_timeout)
...

Abstract
攻撃者はプログラムをクラッシュさせる、あるいは正規ユーザーが利用できなくなるようにする可能性があります。
Explanation
攻撃者は大量のリクエストをアプリケーションに送りつけることで、正規ユーザーへのサービスを拒否させる可能性がありますが、フラッド攻撃は、ネットワークレイヤで除去できる場合があります。さらに解決が難しいのは、攻撃者が数回のリクエストでアプリケーションに過剰な負荷をかけることを可能とするバグです。このようなバグが利用されると、攻撃者はリクエストによって消費するシステムリソースの数量や、システムリソースが使用される期間を指定できるようになります。

例 1: 次のコードは、スレッドがスリープ状態になる時間をユーザーが指定することを許しています。攻撃者は大きな数を指定することで、スレッドを無期限に拘束できます。数回のリクエストで、攻撃者はアプリケーションのスレッド プールを使い果たすことができます。


  Kernel.sleep(user_input)
例 2: The following code reads a String from a file.このコードでは、readline() メソッドが制限を指定せずに使用されているため、無制限の入力が読み取られます。攻撃者はこのコードを利用し、メモリを大量に使用してプロセスをハングアップさせることができます。最終的にメモリをすべて使い果たすことがあります。


  fd = File.new(myFile)
  line = fd.readline
