CVE-2022-0883

Local privilege escalation via unquoted service paths

Published May 18, 2022 · Updated Aug 2, 2024

Unquoted service paths in Snow License Manager 9.x before 9.20.1 allow local users to execute code with service privileges. Snow Software has not identified the affected Windows service, but its executable path is registered without required quotation marks, allowing Windows service startup parsing to select an attacker-controlled executable from an earlier path segment. Exploitation requires low-privileged local access, a writable directory in the ambiguous path, and user interaction to trigger the affected service, after which code runs with that service's privileges.
