CVE-2023-38176

Local privilege escalation via undisclosed path traversal

Published Aug 8, 2023 · Updated Aug 10, 2026

Path traversal in Microsoft Azure Arc-enabled servers before 1.33.02399.0 allows local users to elevate privileges on the host. Microsoft has not published which Connected Machine agent component accepts the traversing path or which privileged file operation follows it. Exploitation requires a low-privileged local user and high-complexity conditions; success grants elevated control over host data and services.
