These entities can access local or remote content. Īn external XML entity - xxe, is defined using a system identifier and present within a DOCTYPE header. When an XML document is being parsed, the parser can make a request and include the content at the specified URI inside of the XML document.Īttacks can include disclosing local files, which may contain sensitive data such as passwords or private user data, using file: schemes or relative paths in the system identifier.įor example, below is a sample XML document, containing an XML element- username. By default, many XML processors allow specification of an external entity, a URI that is dereferenced and evaluated during XML processing. XML is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable.
