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。

Spring Beans Injection

Java/JSP

Abstract

ユーザー制御 Bean 定義リソースをロードすると、攻撃者によるサーバーでの任意のコードの実行、アプリケーションロジックの悪用、サービス拒否の原因になります。

Explanation

開発有効は、Spring により、Bean 定義をローカルファイルやリモート URL を含む複数のリソースからロードできます。攻撃者は、Bean 定義リソースのコンテンツを制御できる場合は、初期化時の任意コードの実行を可能にする悪意のある Bean 定義を注入できます。

例: 次の例では、Bean 定義リソースをユーザーが制御している場所からロードします。


String beans = getBeanDefinitionFromUser();
GenericApplicationContext ctx = new GenericApplicationContext();
XmlBeanDefinitionReader xmlReader = new XmlBeanDefinitionReader(ctx);
xmlReader.loadBeanDefinitions(new UrlResource(beans));
ctx.refresh();
