Untrusted XML input parsing possible in Configuration Wizard, SAP security note 2235994

Description

A attacker can modify an XML-based request to include malicious XML content that is then parsed locally.
This could allow a malicious user to perform a denial of service (DoS) on the parsing system, or disclose local data that is then returned in the response to the malicious request, or access further network-located resources that are accessible from the parsing system.
