Oracle Exadata Infiniband Switch Default Logins / Poor Configuration

`Oracle Exadata Infiniband Switch default logins and world readable shadow file  
  
Hi Full-Disclosure List,  
  
I've noticed a minor issue with the 1/4 rack Oracle Exadata Solution.  
  
What is Exadata?  
  
From Oracle.com "Oracle Exadata is the only database machine that provides extreme performance for both data warehousing and OLTP  
applications, making it the ideal platform for consolidating on private clouds. It is a complete package of servers, storage, networking,  
and software that is massively scalable, secure, and redundant. With Oracle Exadata customers can reduce IT costs through consolidation,  
store up to ten times more data, improve performance of all applications, deliver a faster time-to-market by eliminating systems integration   
trial and error, and make better business decisions in real time."

The oracle engineered solution contains two leaf switches and in larger installations a spine switch. The installation I worked with didn't  
have a spine switch, but the two leaf switches were configured with three logins with easily guessable passwords and a shadow file  
that was world readable.  
  
There are three accounts with easily guessable default passwords on the   
exadata inifiniband switches:  
  
ilom-admin, ilom-operator and nm2user.  
  
rux0r:~ meep0$ ssh [email protected] "cat /conf/shadow"  
  
The shadow file is world readable:  
  
[root@exad-1swib2 ~]# ls -l /conf/shadow  
-rw-r--r-- 1 root root 749 Dec 23 2011 /conf/shado  
  
  
Vendor: notified 3/12/2012  
  
Fix:   
  
Rotate default passwords. I am checking on if you can lock down file permissions on /conf/shadow with out causing issues.
