CVE-2016-20093Public exploit

SYSTEM code execution via unquoted service paths

Published Jun 19, 2026 · Updated Jun 19, 2026

Unquoted service paths in Wise Care 365 4.27 and Wise Disk Cleaner 9.29 allow local users to execute arbitrary code as SYSTEM. The WiseBootAssistant and SpyHunter 4 Service ImagePath values contain spaces without enclosing quotes, causing Windows to search executable path prefixes. A local user must place an executable in an earlier writable path and wait for service startup or system reboot, after which the file runs with SYSTEM privileges.
