Background:

The mentioned product installs an ActiveX control
with the following settings:

According to the IObjectSafety interface it is
safe for scripting and safe for initialization, so
Internet Explorer will allow scripting of this control
from remote.

Vulnerability:

By invoking the Add() method is
possible to call inside a memory region of choice
set by the attacker through ex. heap spray or other
tecniques.

Example code:

...
eax=76767676 ebx=4401e51c ecx=01f85340 edx=00000000 esi=01f85340 edi=00000001
eip=4400ae62 esp=015fd134 ebp=015fd140 iopl=0         nv up ei pl nz na po nc
cs=001b ss=0023 ds=0023 es=0023 fs=003b gs=0000             efl=00010202
ANNOTA_1+0xae62:
4400ae62 ff1485504a0244 call    dword ptr ANNOTA_1!DllUnregisterServer+0x19235 (44024a50)[eax*4] ds:0023:1ddc2428=????????
...

You are in control of eax: fully exploitable.
As attachment, proof of concept code.
