Finding ID	Version	Rule ID	IA Controls	Severity
V-1152	3.030	SV-32260r1_rule	ECCD-1 ECCD-2	High

Description
This is a Category I finding, because this vulnerability allows an anonymous individual read-access and write-access to some parts of the registry. The permissions set for the Winreg subkey determine who can remotely connect to a registry. If this subkey does not exist, all users can remotely connect to the registry. To remotely connect to a registry, a user must have at least Read Access to the Winreg subkey on the target computer. The Everyone group, which is given permissions by the default installation, typically has at least enough access allowed to browse. Therefore, the capability for an anonymous user to access the registry over the network must be prevented.
