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: Plugin Framework Not In Use

Abstract
Struts Validator を使用して、入力の未検証に起因する脆弱性を防ぎます。
Explanation
入力の未検証は、J2EE アプリケーションの脆弱性の主な原因です。入力の未検証は、Cross-Site Scripting、Process Control、SQL Injection など、さまざまな脆弱性の原因となる可能性があります。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。

このような攻撃を防ぐには、Struts Validator を使用して、アプリケーションで処理される前にすべてのプログラム入力をチェックします。Fortify Static Code Analyzer を使用して、Struts Validator の設定に欠陥がないことを確認します。

このバリデーターの使用例として、次の内容を確認するためのチェックがあります。

- 電話番号フィールドには、電話番号に有効な文字のみが含まれている。

- ブール値は T または F のみである。

- 自由形式の文字列が適度な長さと設定になっている。
