Disabling the Windows Sidebar and Gadgets can help protect customers from vulnerabilities that involve the execution of arbitrary code by the Windows Sidebar when running insecure Gadgets. In addition, Gadgets installed from untrusted sources can harm your computer and can access your computer's files, show you objectionable content, or change their behavior at any time. An attacker who successfully exploited a Gadget vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take complete control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. Applying the automated Microsoft Fix It solution described in Microsoft Knowledge Base Article 2719662 disables the Windows Sidebar experience and all Gadget functionality. Recommendation. Customers who are concerned about vulnerable or malicious Gadgets should apply the automated Fix It solution as soon as possible. For more information, see the Suggested Actions section of this advisory.
