CVE-2021-47833Public exploit

LocalSystem code execution via unquoted service path

Published Jan 16, 2026 · Updated Jan 16, 2026

Unquoted service path handling in Gear Box Computers Wifi HotSpot 1.0.0.0 allows local users to execute code as LocalSystem. The WifiHotSpotSvc configuration registers C:\Program Files (x86)\WifiHotSpot\WifiHotSpotService.exe as an unquoted AUTO_START binary path despite its spaces. A low-privileged local user who can place an executable in a searched parent directory can have it launched at startup or reboot with LocalSystem privileges.
