LocalSystem code execution via unquoted service path
Published Jan 13, 2026 · Updated Jan 13, 2026
Unquoted service path in DFWSIDService in Wondershare Dr.Fone 11.4.9 allows local users to execute code as LocalSystem. The service registers WsidService.exe under an unquoted path containing spaces, letting Windows resolve an attacker-placed executable first. Exploitation requires write access to a parent directory and execution of the auto-start service during application startup or reboot.
