📋 Description

An information disclosure vulnerability exists when .NET Framework improperly parses XML input containing a reference to an external entity. An attacker who successfully exploited this vulnerability could read arbitrary files via an XML external entity declaration. To exploit the vulnerability, an attacker could create specially crafted XML data and induce an application to parse and validate the XML data. For example, an attacker could create an XML file and upload it to a web-based application. The update addresses the vulnerability by modifying the way that the XML External Entity (XXE) parser parses XML input.
