Last updated on: 2026-03-11

Assigner: Progress Software Corporation

Description
Chef InSpec versions up to 5.23 and before 7.0.107 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 and before 7.0.107

Executive Summary

Chef InSpec up to version 5.23 creates named pipes on Windows with overly permissive access controls. This allows a local attacker to interfere with the pipe connection process and exploit these weak permissions to assume the InSpec execution context, potentially leading to elevated privileges or disruption of operations.

Impact Analysis

This vulnerability can allow a local attacker to gain elevated privileges by exploiting the insufficient access restrictions on named pipes, which may result in unauthorized actions or operational disruptions within the affected system.

Mitigation Strategies

To mitigate this vulnerability, upgrade Chef InSpec to a version later than 5.23 where the issue with overly permissive named pipe access controls is resolved. Additionally, restrict local user permissions to prevent unauthorized access to named pipes until the upgrade is applied.
