Summary
SSLv3 contains a vulnerability that has been referred to as the Padding
Oracle On Downgraded Legacy Encryption (POODLE) attack. SSLv3 is enabled
in Platform Cluster Manager and Platform HPC.
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 other
areas that enable the SSLv3 protocol and take appropriate mitigation such
as disabling SSLv3 and remediation actions.
If you have HTTPS enabled, complete the following steps. Otherwise, no
action is required.
For Platform Cluster Manager Standard Edition and Platform HPC:
1. Source your environment.
- - For Platform HPC Version 3.2 or Platform Cluster Manager Version 3.2,
run the following command:
# source /opt/kusu/bin/pcmenv.sh
- - For Platform HPC Version 4.1.1 or 4.1.1.1, run the following command:
# source /opt/pcm/bin/pcmenv.sh
- - For Platform Cluster Manager Version 4.1, 4.1.1, or 4.1.1.1, run the
following command:
# source /opt/pcm/bin/pcmenv.sh
2. Edit the $GUI_CONFDIR/server.xml file. In the connector XML tag, set
the sslProtocol value from SSL to TLS, and save the file. For example:
<Connector port="${CATALINA_HTTPS_START_PORT}" maxHttpHeaderSize="8192"
maxThreads="${CATALINA_MAX_THREADS}" minSpareThreads="25"
maxSpareThreads="75"
enableLookups="false" disableUploadTimeout="true"
acceptCount="100" scheme="https" secure="true"
clientAuth="want" sslProtocol="TLS" algorithm="ibmX509"
compression="on" compressionMinSize="2000"
compressableMimeType="text/html,text/xml,text/css,text/javascript,text/plain"
connectionTimeout="20000" URIEncoding="UTF-8"/>
Note:
If you have a high availability environment enabled in Platform HPC Version
3.2 or Platform Cluster Manager Version 3.2, the server.xml file must be
modified on the master host and on the master candidate host.
If you have a high availability environment enabled in Platform HPC Version
4.1.1 or later, the server.xml must be modified on the primary management
node only.
If you have a high availability environment enabled in Platform Cluster
Manager Version 4.1 or later, the server.xml must be modified on the
primary management node only.
3. Restart the Web Portal service.
- - If a high availability environment is not enabled, run the following
command:
# pmcadmin stop
# pmcadmin start
- - If a high availability environment is enabled:
- - For Platform HPC Version 3.2 or Platform Cluster Manager Version 3.2,
run the following command on the master host:
# pmcadmin stop
# pmcadmin start
- - For Platform HPC Version 4.1.1 or 4.1.1.1, run the following command on
the primary management node:
# pcm-ha-support stop --service WEBGUI
# pcm-ha-support start --service WEBGUI
- - For Platform Cluster Manager Version 4.1, 4.1.1, or 4.1.1.1, run the
following command on the primary management node:
# pcm-ha-support stop --service WEBGUI
# pcm-ha-support start --service WEBGUI
For Platform Cluster Manager Advanced Edition:
1. Edit the install_dir/gui/conf/server.xml file. In the connector XML
tag, set the sslProtocol value from SSL to TLS, and save the file,
where install_dir is the top-level management server installation
directory. install_dir is set to /opt/platform by default. For example:
<Connector port="${CATALINA_HTTPS_START_PORT}" maxHttpHeaderSize="8192"
maxThreads="${CATALINA_MAX_THREADS}" minSpareThreads="25"
maxSpareThreads="75"
enableLookups="false" disableUploadTimeout="true"
acceptCount="100" scheme="https" secure="true"
clientAuth="want" sslProtocol="TLS" algorithm="ibmX509"
compression="on" compressionMinSize="2000"
compressableMimeType="text/html,text/xml,text/css,text/javascript,text/plain"
connectionTimeout="20000" URIEncoding="UTF-8"/>
Note:
If a high availability environment is enabled, the path to the server.xml
is SHAREDDIR/gui/conf/server.xml, where SHAREADDIR is the directory set
by the users during the installation process. The server.xml only needs
to be modified on the primary management node.
2. Restart the Web Portal service.
# egosh user logon -u Admin -x Admin
# egosh service stop WEBGUI
# egosh service start WEBGUI
Note:
If a high availability environment is enabled, only restart the Web Portal
service on the primary management node.
