Name of the Vulnerable Software and Affected Versions Chef InSpec versions through 5.23

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.
