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。
Bean Manipulation
Abstract
攻撃者がシステムの整合性を危険にさらす任意の bean プロパティを設定する可能性があります。
Explanation
bean を入力する前に bean プロパティ名および値を検証する必要があります。bean の入力機能によって、開発者は bean プロパティまたはネストされたプロパティを設定できます。攻撃者がこの機能を利用して、システム プロパティを上書きし、任意のコードを実行できるようにする
例: 次のコードは、プロパティ名または値の適切な検証を行うことなく、ユーザー制御の bean プロパティを設定します。
class.classLoader のような特殊な bean プロパティにアクセスする可能性があります。例: 次のコードは、プロパティ名または値の適切な検証を行うことなく、ユーザー制御の bean プロパティを設定します。
String prop = request.getParameter('prop');
String value = request.getParameter('value');
HashMap properties = new HashMap();
properties.put(prop, value);
BeanUtils.populate(user, properties);
