CVE-2024-50590

High
Published: Translated: NVD NIST

Summary

Attackers with local access to the medical office computer can escalate their Windows user privileges to 'NT AUTHORITY\SYSTEM' by overwriting one of two Elefant service binaries with weak permissions. The default installation directory 'C:\Elefant1' is writable for all users, and the installer registers two Firebird services running as SYSTEM.

Risk Assessment

The risk is that a local attacker can gain full system control, potentially leading to theft of patient data, modification of medical software, or further attacks on the clinic's network.

Recommendation

Immediately change permissions on the 'C:\Elefant1' directory and the fbserver.exe and fbguard.exe files so that only trusted accounts (e.g., SYSTEM and Administrators) have write access. Consider moving the installation to a directory with restrictive permissions.

Original NVD description (English source)

Attackers with local access to the medical office computer can escalate their Windows user privileges to "NT AUTHORITY\SYSTEM" by overwriting one of two Elefant service binaries with weak permissions. The default installation directory of Elefant is "C:\Elefant1" which is writable for all users. In addition, the Elefant installer registers two Firebird database services which are running as “NT AUTHORITY\SYSTEM”.  Path: C:\Elefant1\Firebird_2\bin\fbserver.exe Path: C:\Elefant1\Firebird_2\bin\fbguard.exe Both service binaries are user writable. This means that a local attacker can rename one of the service binaries, replace the service executable with a new executable, and then restart the system. Once the system has rebooted, the new service binary is executed as "NT AUTHORITY\SYSTEM".
