Recommendation: Plan a near-term fix — a public PoC already exists.

OKI sPSV Port Manager 1.0.41 contains an unquoted service path vulnerability in the sPSVOpLclSrv service that allows local attackers to escalate privileges by inserting executable files into the unquoted path. Attackers can place a malicious executable in a directory within the service path that will execute with LocalSystem privileges when the service restarts or the system reboots.
