Description
Chef InSpec up to version 5.23 creates named pipes with overly permissive default Windows access controls. A local attacker may interfere with the pipe connection process and exploit the insufficient access restrictions to assume the InSpec execution context, potentially resulting in elevated privileges or operational disruption. This issue affects Chef Inspec: through 5.23.
