ConfigFree is the registered file handler for the cf7 filetype (CFProfile.exe at HKEY_CLASSES_ROOT\cf7_auto_file\shell\open\command) so if a victim could be convinced to download and apply a crafted cf7 file the commands in the runApp field would be executed and could be used to take control of the machine.

Impact
