There is a flaw in how the System Attendant makes these Registry configuration changes. This flaw could allow an unprivileged user to remotely access configuration information on the server. Specifically, this flaw inappropriately gives the "Everyone" group privileges to the WinReg key. This key controls the ability of users and groups to remotely connect to the Registry. By default, only Administrators are given the ability to remotely connect to the Registry, by granting permissions on this key.

The flaw does not grant any abilities beyond the ability to connect remotely. However, an attacker?s ability to make changes to the Registry once they have successfully connected would be dictated by the permissions on the specific keys within the Registry itself. Thus, while this vulnerability does not itself give an attacker the ability to change Registry settings, it could be used in conjunction with inappropriately permissive registry settings to gain access to, and make changes to a systems Registry.
