CVE-2020-37064Public exploit

Local privilege escalation via unquoted service path

Published Feb 1, 2026 · Updated Feb 1, 2026

Unquoted service path handling in Epson EasyMP Network Projection 2.81 allows local users to execute code as LocalSystem. The EMP_NSWLSV service registers its executable path under Program Files without quotes, allowing Windows to resolve an earlier whitespace-delimited executable. A local user must place code in a writable path candidate and trigger service startup or a reboot, after which that code runs with LocalSystem privileges.
