An attacker with local access the to medical office computer can
escalate his Windows user privileges to "NT AUTHORITY\SYSTEM" by
exploiting a command injection vulnerability in the Elefant Update
Service. The command injection can be exploited by communicating with
the Elefant Update Service which is running as "SYSTEM" via Windows
Named Pipes.The Elefant Software Updater (ESU) consists of two components. An ESU
service which runs as "NT AUTHORITY\SYSTEM" and an ESU tray client
which communicates with the service to update or repair the installation
and is running with user permissions. The communication is implemented
using named pipes. A crafted message of type
"MessageType.SupportServiceInfos" can be sent to the local ESU service
to inject commands, which are then executed as "NT AUTHORITY\SYSTEM".
