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. When the user disable the SSLv3 in the service environment, it
may cause the servlet search and RSS feed to fail (Only appeared when the
server use the IBM JDK until now).

Workarounds and Mitigations
Disable SSLv3
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.
SSL secured communication occurs between client and server, for example
between a Web browser and a Web server on which the RMC site is published. To
mitigate this issue and protect against POODLE attack, it is enough to secure
either the client or the server (or both). One suggestion is to secure the Web
server. This will allow you some flexibility in terms of addressing this issue
as applicable in your environments while at the same time maintaining the
ability of software client applications/components to access servers
configured with different levels of security.
See the following links for information on how to disable SSLv3 in Apache
Tomcat, IBM WebSphere and IBM HTTP Server.
IBM WebSphere: http://www.ibm.com/support/docview.wss?uid=swg21687173
IBM HTTP Server: http://www.ibm.com/support/docview.wss?uid=swg21687172
Apache Tomcat: https://access.redhat.com/solutions/1232233
Disabling SSLv3 will affect RMC publised war/ear
When the user disable the SSLv3 in the service environment, it may cause the
servlet search and RSS feed to fail (Only appeared when the J2EE server use
the IBM JRE until now). When this happens, you can try the mitigation
below,but we strongly suggest follow the workaround below, or install the iFix
update in the above links.
Mitigations
Change the server IBM JRE to Oracle JRE temporary.(If you are using
Websphere,we suggest you do not follow this mitigation)
Tomcat:how to change jre
WORKAROUND:
Publish RMC site as static site .
