Privacy Drive 3.17.0 contains an unquoted service path vulnerability in the pdsvc.exe service binary that allows local attackers to escalate privileges by exploiting the service startup process. Attackers can place malicious executables in the unquoted path directories to execute arbitrary code with LocalSystem privileges during service startup or system reboot.
