This security update resolves a vulnerability in the VBScript scripting engine in Microsoft Windows. The vulnerability could allow remote code execution if a user visits a specially crafted website. An attacker who successfully exploited this vulnerability could gain the same user rights as the current user. If the current user is logged on by using administrative user rights, an attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then do the following:
- Install programs
- View, change, or delete data
- Create new accounts that have full user rights
