just so we're all clear, SuperMicro wasn't the only one...

1.  CVE-2013-4782 CVSS Base Score = 10.0
2.  The SuperMicro BMC implementation allows remote attackers to
bypass authentication and execute arbitrary IPMI commands by using
cipher suite 0 (aka cipher zero) and an arbitrary password.
3.
4.  CVE-2013-4783 CVSS Base Score = 10.0
5.  The Dell iDRAC 6 BMC implementation allows remote attackers to
bypass authentication and execute arbitrary IPMI commands by using
cipher suite 0 (aka cipher zero) and an arbitrary password.
6.
7.  CVE-2013-4784 CVSS Base Score = 10.0
8.  The HP Integrated Lights-Out (iLO) BMC implementation allows
remote attackers to bypass authentication and execute arbitrary IPMI
commands by using cipher suite 0 (aka cipher zero) and an arbitrary
password.
9.
10. CVE-2013-4785 CVSS Base Score = 10.0
11. iDRAC 6 firmware 1.7, and possibly other versions, allows remote
attackers to modify the CLP interface for arbitrary users and possibly
have other impact via a request to an unspecified form that is
accessible from testurls.html.
12.
13. CVE-2013-4786 CVSS Base Score = 7.8
14. The IPMI 2.0 specification supports RMCP+ Authenticated
Key-Exchange Protocol (RAKP) authentication, which allows remote
attackers to obtain password hashes and conduct offline password
guessing attacks by obtaining the HMAC from a RAKP message 2 responses
from a BMC.
