本節包括原始程式碼之外的所有內容，但對於建立中產品的安全性仍至關重要。由於此領域所涵蓋的問題與原始程式碼沒有直接關係，因此我們將其與其他領域分開。

Weak XML Schema: Undefined Namespace

Universal

Abstract

指定 <any> 元素中 ##any 的命名空間，表示允許使用在結構中沒有明確定義的元素，導致惡意修改文件變得更加容易。

Explanation

未限制元素命名空間的結構，將允許有效文件中包含任意元素。對攻擊者而言，執行 XML 插入之類的攻擊較為輕鬆，只要包含未遵守文件其他部分所限標準的標籤即可。

下列結構允許不受限制的命名空間。


<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>
