Vulnerability
Users who can connect from their computer to the network can access resources on target computers for which they have permission. For example, the Access this computer from the network user right is required for users to connect to shared printers and folders. If this user right is assigned to the Everyone group, anyone in the group can read the files in those shared folders. This situation is unlikely because the groups created by a default installation of Windows Server 2012, Windows Server 2008 R2, Windows 8, and Windows 7 do not include the Everyone group. However, if a computer is upgraded and the original computer includes the Everyone group as part of its defined users and groups, that group is transitioned as part of the upgrade process and is present on the computer.
Countermeasure
Restrict the Access this computer from the network user right to only those users and groups who require access to the computer. For example, if you configure this policy setting to the Administrators and Users groups, users who log on to the domain can access resources that are shared from servers in the domain if members of the Domain Users group are included in the local Users group.
