Background:

the mentioned program installs an ActiveX control with the following
settings:

Binary Path: C:\WINDOWS\system32\TList6.ocx
ProgID: TList.TList.6
CLSID: {65996200-3B87-11D4-A21F-00E029189826}
Safe for Initialization (Registry): True
Safe for Scripting (Registry): True

This control is marked "safe for scripting" and "safe for initialization",
Internet Explorer will allows scripting of this control.


Vulnerability:

The mentioned class contains the vulnerable SaveData() method, see typelib:

..
        /* DISPID=167 */
        /* VT_I2 [2] */
        function SaveData(
                /* VT_BSTR [8]  */ $lpszFileName 
                )
        {
        }
..

which allows to create / overwrite files with arbitrary extensions
inside arbitrary locations ex. automatic startup folders. By manipulating 
ex. the Caption property is possible to create a valid application 
with .hta extension.

The resulting file will look like this:
