Local privilege escalation via unquoted service path
Published Aug 29, 2025 · Updated Aug 29, 2025
Unquoted service paths in Hikvision HikCentral FocSign 1.4.0 through 2.2.0 allow local users to escalate privileges on Windows. An affected service registration leaves a path containing spaces unquoted, allowing Windows to resolve an attacker-placed executable before the intended service binary. Exploitation requires authenticated local access and permission to place an executable in a searched parent path; the executable then runs with the service account's privileges.
