XPath Injection

XPath Injection is an attack technique used to exploit applications that construct XPath (XML Path Language) queries from user-supplied input to query or navigate XML documents. It can be used directly by an application to query an XML document, as part of a larger operation such as applying an XSLT transformation to an XML document, or applying an XQuery to an XML document. The syntax of XPath bears some resemblance to an SQL query, and indeed, it is possible to form SQL-like queries on an XML document using XPath.
