CVE-2024-50591

High
Published: Translated: NVD NIST

Summary

A vulnerability in the Elefant Update Service allows a local attacker to escalate privileges to SYSTEM by injecting commands into communication via Windows named pipes. Sending a crafted MessageType.SupportServiceInfos message to the ESU service running as SYSTEM is sufficient.

Risk Assessment

An attacker with local access to the medical office computer can gain full control over the operating system, potentially compromising patient data confidentiality and integrity and disrupting medical software operations.

Recommendation

Immediately update the Elefant Update Service to the latest patched version. Until then, restrict local access to workstations and monitor named pipe communication.

Original NVD description (English source)

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".
