Weakness (CWE)

CWE-112: Missing XML Validation

Base Draft

The product accepts XML from an untrusted source but does not validate the XML against the proper schema.

How to prevent it (1 mitigation)

  1. Architecture and Design

    Always validate XML input against a known XML Schema or DTD.

    It is not possible for an XML parser to validate all aspects of a document's content because a parser cannot understand the complete semantics of the data. However, a parser can do a complete and thorough job of checking the document's structure and therefore guarantee to the code that processes the document that the content is well-formed.
