266794 Windows 2000 SNMP registry entries are saved in plain text format and are readable



SYMPTOMS
Microsoft has released a tool that corrects the permissions on several registry values in Microsoft Windows NT 4.0. The default permissions could allow a malicious user to gain additional privileges on an affected machine.

After you create the PermittedManagers and ValidCommunities registry keys for the Simple Network Management Protocol (SNMP) service, any user has permission to read the contents of the keys. The keys should only be accessible to administrators. SNMP is not installed on Windows NT 4.0 computers by default.

267861 MS00-095: RAS registry modification allowed without administrative rights

267864 MS00-095: MTS package administration key includes information about users
