Affected Products
======== ========

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

operating-system commands.

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
======

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.
