Summary

SSLv3 contains a vulnerability that has been referred to as the Padding Oracle
On Downgraded Legacy Encryption (POODLE) attack. SSLv3 is enabled by default 
in DataPower.

Vulnerability Details

CVE-ID: CVE-2014-3566

DESCRIPTION: Product could allow a remote attacker to obtain sensitive 
information, caused by a design error when using the SSLv3 protocol. A remote
user with the ability to conduct a man-in-the-middle attack could exploit this
vulnerability via a POODLE (Padding Oracle On Downgraded Legacy Encryption) 
attack to decrypt SSL sessions and access the plaintext of encrypted 
connections.

CVSS Base Score: 4.3

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/97013 for the 
current score

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)

Affected Products and Versions

All DataPower products and versions that have configured a DataPower Crypto 
Profile object for SSL communication.

Remediation/Fixes

None

Workarounds and Mitigations

Disable SSL v3 in DataPower configuration.

First make sure to Quiesce all domains and services to stop traffic to the 
appliance. System quiesce and unquiesce commands can be invoked by navigating
to Administration --> Main --> System Control.

Next, select Objects --> Crypto Configuration --> Crypto Profile in the left 
navigation pane. For all the crypto profile objects that are configured, in 
the "Configure Crypto Profile" page, "Options" parameter, select the checkbox
"Disable SSL version 3". Click Apply.

Note that SSL v3 must be disabled in all the Crypto Profile objects configured
in all the domains.

IBM recommends that you review your entire environment to identify other areas
that enable the SSLv3 protocol and take appropriate mitigation such as 
disabling SSLv3 and remediation actions.
