SSLv3 is enabled in IBM Rational Method Composer. 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. 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).

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 .
