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:
