Affected Software Versions:
* Microsoft Windows Live Messenger 4.7 on Windows XP and Windows Server 2003
* Microsoft Windows Live Messenger 5.1 on Windows 2000, Windows XP and Windows Server 2003
When installing Windows XP, an old edition of MSN Messenger is installed automatically. The old edition opens the MSN API to develop as an ActiveX Control, and marks it with "safe".
By using this ActiveX Control, we can control the local MSN Messenger, for instance: change state, gain current login ID, steal contact-person's information, send mail using the victim's name, and so on, all of these functions given by this feature can be considered to be security problems.
Even the user installs a higher edition of MSN Messenger(Windows Live Messenger), this ActiveX control will not be removed. By using this we will still be allowed to visit the local Live Messenger.
Solution:
