Local privilege escalation via unquoted service path
Published Feb 17, 2023 · Updated Mar 12, 2025
Unquoted search path handling in Philippe Jounin Tftpd64 4.64 allows local users to execute code with service privileges. The published record identifies tftpd64_svc.exe but does not disclose the exact unquoted service-registration statement or writable path used to exploit it. Exploitation requires local low-privileged access, control of a searched path element, and a service start; successful execution obtains the service account privileges.
