Affected Products

Confirmed in latest Configfree version 8.0.38 on Windows 7 on a Toshiba Satellite R850. Other versions may also be affected.

Details

The ‘runApp’ field of the cf7 file can be manipulated to run arbitrary operating-system commands. ConfigFree is the registered file handler for the cf7 filetype (CFProfile.exe at HKEY_CLASSES_ROOTcf7_auto_fileshellopencommand) 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

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.

Solution

As no fix is available, concerned users could remove this utility from their machine.
