Security Bulletin
Summary
SSLv3 contains a vulnerability that has been referred to as the Padding Oracle On Downgraded Legacy Encryption (POODLE) attack. SSLv3 is enabled in Jazz technology (JAF) based products such as Rational Team Concert (RTC), Rational Quality Manager (RQM), Rational Requirements Composer/Rational DOORS Next Generation (RRC/RDNG), Rational Engineering Lifecycle Manager (RELM), Rational Software Architect Design Manager (RSA DM), Rhapsody Design Manager (Rhapsody DM) and also in Web servers that these products run on, namely Apache Tomcat, IBM WebSphere, and IBM HTTP Server.
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

Workarounds and Mitigations
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 or RTC client and a Web server on which the CLM is installed. 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 into which CLM is installed. 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
In addition, the following change must be made in server.startup file (.bat or .sh, as appropriate).
This file is located in <CLM_INSTALL_LOCATION>/server folder:
Find and replace the following text in the follow files:
- server.startup.bat
Find: set JAVA_OPTS=%JAVA_OPTS% -Djazz.connector.sslProtocol=SSL_TLS
Replace with: set JAVA_OPTS=%JAVA_OPTS% -Djazz.connector.sslEnabledProtocols=TLSv1,TLSv1.1,TLSv1.2
- server.startup.sh:
Find: JAVA_OPTS="$JAVA_OPTS -Djazz.connector.sslProtocol=SSL_TLS"
Replace with: JAVA_OPTS="$JAVA_OPTS -Djazz.connector.sslEnabledProtocols=TLSv1,TLSv1.1,TLSv1.2"
And the following change must be made in <CLM_INSTALL_LOCATION>\server\tomcat\conf\server.xml
- Find: sslProtocol="${jazz.connector.sslProtocol}"
Tomcat 6 (6.0.38 and later) and 7 replace with: sslEnabledProtocols="${jazz.connector.sslEnabledProtocols}"
Tomcat 5 and 6 (prior to 6.0.38) replace with: sslProtocols="${jazz.connector.sslEnabledProtocols}"

Important Note
IBM strongly suggests that all System z customers be subscribed 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.
