Summary
Document information
More support for:
WebSphere eXtreme Scale
Software version:
7.0, 7.1, 7.1.1, 8.5, 8.6
Operating system(s):

SSLv3 contains a vulnerability that has been referred to as the Padding Oracle
On Downgraded Legacy Encryption (POODLE) attack. SSLv3 is enabled in WebSphere
eXtreme Scale and WebSphere eXtreme Scale for z/OS versions 7.0, 7.1.0, 7.1.1,
8.5, and 8.6.
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
WebSphere eXtreme Scale 7.0 through 8.6.0.5.
WebSphere eXtreme Scale for z/OS 7.0 through 8.6.0.5.
Remediation/Fixes
WebSphere eXtreme Scale 7.0 through 8.6.0.5, WebSphere eXtreme Scale for z/OS
7.0 through 8.6.05: No fix is available or planned, as the problem can be
addressed entirely by configuration.
IBM recommends that you review your entire environment to identify areas that
enable the SSLv3 protocol and take appropriate mitigation and remediation
actions. The most immediate mitigation action that can be taken is disabling
SSLv3.
Workarounds and Mitigations
WebSphere eXtreme Scale clients and servers may run standalone, under the
WebSphere Application Server Liberty Profile or under WebSphere Application
Server. When clients or servers are running under WebSphere Application
Server, WebSphere eXtreme Scale communications may be protected by setting
WebSphere Quality of Protection to TLS as described in this link:
http://www-01.ibm.com/support/docview.wss?uid=swg21687173
If running WebSphere eXtreme Scale 8.6 clients or servers under WebSphere
Application Server and using the XIO protocol, a server.properties or
client.properties file will exist if SSL/TLS encrypted communications is
specified. That file will contain a protocol property, which must be set to
TLS to protect against the attack.
If running WebSphere eXtreme Scale clients or servers under the WebSphere
Application Server Liberty Profile or standalone, a server.properties or
client.properties file will exist if SSL/TLS encrypted communications is
specified. That file will contain a protocol property, which must be set to
TLS to protect against the attack.
If these configuration measures are taken, changes to the clients or servers
will require those components to be restarted so that the changes take effect.
The same measures are used to protect WebSphere eXtreme Scale for z/OS. The
WebSphere eXtreme Scale Client may run under WebSphere Application Server on
z/OS. The WebSphere eXtreme Scale Client or server may run under the Liberty
Profile on z/OS.
Important note: IBM strongly suggests that all System z customers subscribe to
the System z Security Portal to receive the latest critical System z security
and integrity service. If you are not subscribed, see the instructions on the
System z Security web site. Security and integrity APARs and associated fixes
will be posted to this portal. IBM suggests reviewing the CVSS scores and
applying all security or integrity fixes as soon as possible to minimize any
potential risk.
