SAP NetWeaver GRMGApp is vulnerable to unauthorized access and has XXE vulnerability.
It is possible for attackers to send any packets to any port of any system including localhost. It means that it is possible, for example, to send any administrative command to Gateway or Message server because the source of the packet will be localhost, and there is no restrictions for localhost. Another example is an attack on other interfaces.
