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。
.NET Bad Practices: BinaryFormatter Enabled
Abstract
アプリケーションは非推奨かつ安全でない
BinaryFormatter
クラスを有効にします。Explanation
.NET では、
例 1: runtimeConfig.json ファイルで config プロパティ
BinaryFormatter
クラスを使用して、オブジェクトを、オブジェクト自体と、デシリアライズ中にオブジェクトを再構築するために必要なメタデータの両方を含むバイナリ ストリームに変換することができます。BinaryFormatter
クラスを使用すると、攻撃者が任意のコードを実行したり、アプリケーション ロジックを悪用したり、Denial of Service 状態をトリガーしたりする可能性のある、安全でないデシリアライゼーション シナリオを引き起こす可能性があります。 BinaryFormatter
型の使用は危険であり、安全性が確立できないため、データ処理には推奨されません。例 1: runtimeConfig.json ファイルで config プロパティ
EnableUnsafeBinaryFormatterSerialization
を true
に設定することによって、アプリケーションは安全でない BinaryFormatter
クラスの使用を有効にします。
...
AppContext.SetSwitch("System.Runtime.Serialization.EnableUnsafeBinaryFormatterSerialization", true);
...
