SAP Mobile Platform version 2.3 suffers from an XXE injection vulnerability. An attacker can read an arbitrary file on the server by sending a correct XML request with a crafted DTD to/scc/messagebroker/http and reading the reply from the service. An attacker can perform a DoS attack (for example, an XML Entity Expansion attack). A SMB Relay attack is a type of Man-in-the-Middle attack where the attacker asks the victim to authenticate into a machine controlled by the attacker, then relays the credentials to the target. The attacker forwards the authentication information both ways, giving them access.
