Weakness Type

Missing XML Validation

The software accepts XML from an untrusted source but does not validate the XML against the proper schema. Most successful attacks begin with a violation of the programmer's assumptions. By accepting an XML document without validating it against a DTD or XML schema, the programmer leaves a door open for attackers to provide unexpected, unreasonable, or malicious input.
