Weak XML Schema: Undefined Namespace

Universal

Abstract

La especificación de un espacio de nombres de##any en el elemento <any> significa que el esquema permite elementos más allá de lo que se define explícitamente en él, lo que facilita la elaboración de documentos malintencionados.

Explanation

Un esquema que no restringe los espacios de nombres de los elementos permite que se incluyan elementos arbitrarios en un documento válido. Este escenario facilita que los atacantes realicen ataques como la inyección de XML mediante la inclusión de etiquetas que no se ajustan a los estándares impuestos al resto del documento.

El siguiente esquema permite espacios de nombres sin restricciones.


<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>
