Authentication is not required to exploit this vulnerability. The specific flaw exists within the unifid.exe service which binds on port 29010 for a protocol providing RPC-like functionality encapsulated over SSL. This protocol allows a client to make a method call into a module. The 'spf' RPC call is implemented unsafely allowing remote attackers to load arbitrary modules over the network resulting in code execution under the context of the service. -- Vendor Response: Novell has issued an update to correct this vulnerability.
