An injection vulnerability in Barco ClickShare CX-30/20, C-5/10, and ClickShare Bar Pro and Core models, running firmware before 2.21.1, allows physically proximate attackers or local admins to the webUI to trigger OS-level command execution as root.
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
