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。

Struts: Form Does Not Extend Validation Class

Java/JSP

Abstract

すべての Struts フォームは、Validator クラスを拡張する必要があります。

Explanation

Struts Validator を使用するには、フォームで次のいずれかを拡張する必要があります。


ValidatorForm
ValidatorActionForm
DynaValidatorActionForm
DynaValidaorForm

Struts Validator は、これらのクラスの validate() メソッドを実装することでアプリケーションと連動するため、これらのクラスのいずれかを拡張する必要があります。

次のクラスから派生したフォームは、Struts Validator を使用できません。


ActionForm
DynaActionForm

フォームの検証フレームワークをバイパスすると、アプリケーションがさまざまな種類の攻撃にさらされます。入力の未検証は、Cross-Site Scripting、Process Control、SQL Injection などの脆弱性の根本的な原因です。J2EE アプリケーションは通常はメモリ破損攻撃の影響を受けませんが、J2EE アプリケーションが配列の境界チェックを実行しないネイティブコードと情報をやりとりする場合、攻撃者が J2EE アプリケーションでの入力検証ミスを使用してバッファオーバーフロー攻撃を行う可能性があります。
