CVE-2020-37231Public exploit

LocalSystem code execution via unquoted service path

Published May 16, 2026 · Updated May 16, 2026

Unquoted service path in Cybertron Software Privacy Drive 3.17.0 allows local users to execute code with LocalSystem privileges. The PDSvc configuration starts pdsvc.exe from an unquoted C:\Program Files (x86)\Cybertron\Privacy Drive path, so Windows can select an attacker-placed executable from an earlier path segment. A local low-privileged user needs write access to a searched directory and service startup or a reboot to gain LocalSystem code execution.
