Successful exploitation of this vulnerability makes it possible for someone within the hospital network to remotely shut down or restart the workstation. In the event the workstation is remotely shut down, physicians are still able to use diagnostic imaging from the X-ray system.
This issue affects four Haswell workstations labeled with 12NC identification numbers (4598 009 39471, 4598 009 39481, 4598 009 70861, 4598 009 98531) when running the following versions of interventional software:
The software constructs all or part of an OS command using externally influenced input from an upstream component but does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when sent to a downstream component.
CVE-2020-27298 has been assigned to this vulnerability. A CVSS v3 base score of 6.5 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).
