Windows Task Scheduler vulnerability
An attacker could exploit Task Scheduler vulnerability by running a specially crafted application which allows elevated privileges to the logged on user. Therefore, an attacker needs to have a valid logon user account in order to be able to exploit this weakness. This vulnerability affects Windows Vista, Windows 7, Windows Servers 2008 and 2008 R2. Microsoft has released a security update that addresses the weakness in Task Scheduler while users who have enabled automatic updating need not to worry as the fix was included in December 2010 release updates.
