Workarounds

BrightSign recommends the following security practices: * Change default passwords when the device is initially set up. * Disable the local DWS as described in "High Security settings". * Disable the SSH/telnet server when not being used - it is not enabled by default. * Devices should be located where an attacker does not have physical access to the device. * SD and USB ports can be disabled if not needed. For more information, please contact BrightSign via their website. https://www.brightsign.biz/contact-us/

Local Privilege Escalation via Weak Service Binary Permissions

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".

A vulnerability in the CLI of Cisco SD-WAN Software could allow an authenticated, local attacker to gain elevated privileges on an affected system. This vulnerability exists because the affected software does not properly restrict access to privileged processes. An attacker could exploit this vulnerability by invoking a privileged process in the affected system. A successful exploit could allow the attacker to perform actions with the privileges of the root user.
