Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
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".

La inyecci\u00f3n de comandos se puede explotar comunic\u00e1ndose con el Servicio de actualizaci\u00f3n de Elefant que se ejecuta como \"SYSTEM\" a trav\u00e9s de canalizaciones con nombre de Windows. El Actualizador de software de Elefant (ESU) consta de dos componentes. Un servicio ESU que se ejecuta como \"NT AUTHORITY\\SYSTEM\" y un cliente de bandeja de ESU que se comunica con el servicio para actualizar o reparar la instalaci\u00f3n y se ejecuta con permisos de usuario. La comunicaci\u00f3n se implementa mediante canalizaciones con nombre. Se puede enviar un mensaje manipulado de tipo \"MessageType.SupportServiceInfos\" al servicio ESU local para inyectar comandos, que luego se ejecutan como \"NT AUTHORITY\\SYSTEM\"."
