The remote Windows host is missing a security update. It is, therefore, affected by a remote code execution vulnerability in the VBScript engine due to improper handling of objects in memory. An attacker can exploit this vulnerability by convincing a user to visit a specially crafted website or open a Microsoft Office document containing an embedded ActiveX control, resulting in execution of arbitrary code in the context of the current user.
