WinCVS is a free app for Windows that will help you simplify the development of files for groups of people working on
the same software project.
WinCvs.exe installs a service with an unquoted service path running with SYSTEM privileges, to exploit a local attacker must place
a malicious executable file named "Program.exe" in the path of the service. After service restart or system reboot, it could
potentially allow an authorized local user to execute arbitrary code with elevated privileges on the system.
