<bug_vulnerability_class>Configuration</bug_vulnerability_class>
<bug_description>This detects the CIS ports by connecting to the server and  processing the buffer received. CIS (COM+ Internet Services) are RPC over HTTP tunneling and requires IIS to operate. CIS ports shouldn't be visible on internet but only behind a firewall. If you do not use this service, then disable it as it may become a security threat in the future, if a vulnerability is discovered.</bug_description>
<bug_solution>Disable CIS with DCOMCNFG or protect CIS ports by a Firewall. See http://support.microsoft.com/support/kb/articles/Q282/2/61.ASP and for more information about CIS go to http://msdn.microsoft.com/library/en-us/dndcom/html/cis.asp</bug_solution>
