SAP Hostcontrol does not require authentication for the SOAP SAPControl endpoint. This is SAP Security Note 2442993.

SAP Host Agent, version 7.21, allows an attacker with admin privileges to use the operation framework to gain root privileges over the underlying operating system, leading to Privilege Escalation.

An attacker authenticated as a non-admin user with local access to a server port assigned to the SAP Host Agent (Start Service) - versions 7.21, 7.22, can submit a crafted ConfigureOutsideDiscovery request with an operating system command which will be executed with administrator privileges.  The OS command can read or modify any user or system data and can make the system unavailable.
