CVE-2023-36723

Local privilege escalation via improper link resolution

Published Oct 10, 2023 · Updated Apr 14, 2025

Improper link resolution in Microsoft Windows Container Manager Service allows local users to elevate privileges on affected Windows systems. Microsoft identifies CWE-59 but has not published the affected function, file operation, or attacker-controlled link path. A low-privileged user must execute code locally; successful exploitation grants higher privileges within the host operating system.
