CVE-2021-0112

Local privilege escalation via unquoted service path

Published Jun 9, 2021 · Updated Aug 3, 2024

Unquoted service path in Intel Unite Client for Windows before 4.2.25031 allows local users to gain elevated privileges. The client registers a Windows service executable path containing spaces without enclosing the full path in quotation marks. A low-privileged local user must place a chosen executable in an earlier-resolved path segment and trigger the service to run it with the service account's privileges.
