In order to prevent XML External Entity vulnerability in SAP NetWeaver ABAP Server and ABAP Platform (Process Integration - Enterprise Service Repository JAVA Mappings), versions - 7.10, 7.20, 7.30, 7.31, 7.40, 7.50, SAP recommends to refer this note.

Under certain conditions the PI Integration Builder Web UI of SAP NetWeaver Process Integration (versions: SAPXIESR: 7.10 to 7.11, 7.20, 7.30, 7.31, 7.40, 7.50, SAPXITOOL: 7.10 to 7.11, 7.30, 7.31, 7.40, 7.50 and SAPXIPCK 7.10 to 7.11, 7.20, 7.30) allows an attacker to access passwords used in FTP channels leading to information disclosure.

SAP NetWeaver Process Integration (Adapter Engine), fixed in versions 7.10 to 7.11, 7.30, 7.31, 7.40, 7.50; is vulnerable to Digital Signature Spoofing. It is possible to spoof XML signatures and send arbitrary requests to the server via PI Axis adapter. These requests will be accepted by the PI Axis adapter even if the payload has been altered, especially when the signed element is the body of the xml document.
