Weak XML Schema: Undefined Namespace
Abstract
<any> 要素に名前空間の ##any を指定することは、スキーマが、明示的に定義されたものを超える要素を許可することを意味し、結果的に、悪意のあるドキュメントの作成が容易になります。Explanation
要素の名前空間を制限しないスキーマは、有効なドキュメントに任意の要素を組み込むことを許可します。これにより攻撃者は、ドキュメントの他の部分で必須の基準に準拠しないタグを組み込むことで、XML インジェクションなどの攻撃を簡単に実行できてしまいます。
次のスキーマは、無制限の名前空間を許可します。
次のスキーマは、無制限の名前空間を許可します。
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" >
<xs:element name='foo'>
<xs:complexType>
<xs:sequence>
<xs:any namespace='##any' />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
