This is due to insufficient filtering of template attributes during the creation of HTML for custom widgets This makes it possible for authenticated attackers, with administrator-level access and above, to execute arbitrary commands on the server.
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
