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 by default
in IBM WebSphere Application Server Community Edition.
Vulnerability Details
CVE ID: CVE-2014-3566
DESCRIPTION: IBM WebSphere Application Server Community Edition 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 Application Server Community Edition 3.0.0.4
Workarounds and Mitigations
When using WebSphere Application Server Community Edition (WASCE) with the
JSSE connectors, the SSL protocol to be used can be configured via
<WASCE_HOME>\var\catalina\server.xml. The following example shows how the
SSLProtocol in an https connector is configured.
<!-- Define a SSL HTTP/1.1 Connector on port 8443
This connector uses the JSSE configuration, when using APR, the
connector should be using the OpenSSL style configuration
described in the APR documentation -->
<Connector SSLEnabled="true" address="${ServerHostname}" clientAuth="false"
executor="DefaultThreadPool"
keystoreFile="../security/keystores/geronimo-default"
keystorePass="{Simple}rO0ABXNyABlqYXZheC5jcnlwdG8uU2VhbGVkT2JqZWN0PjY9psO3VHACAARbAA1lbmNvZGVkUGFyYW1zdAACW0JbABBlbmNyeXB0ZWRDb250ZW50cQB+AAFMAAlwYXJhbXNBbGd0ABJMamF2YS9sYW5nL1N0cmluZztMAAdzZWFsQWxncQB+AAJ4cHB1cgACW0Ks8xf4BghU4AIAAHhwAAAAEArVToThqcjvbXFD5C2uUmpwdAADQUVT"
maxThreads="150" name="TomcatWebSSLConnector" port="${HTTPSPort + PortOffset}"
protocol="HTTP/1.1" scheme="https" secure="true"
sslProtocol="TLSv1,TLSv1.1,TLSv1.2"/>
When using WASCE with APR/Native connectors, the SSL protocol to be used can
be configured via <WASCE_HOME>\var\catalina\server.xml. The following example
shows how the SSLProtocol in an https connector is configured.
<Connector port="443" maxHttpHeaderSize="8192"
maxThreads="150"
enableLookups="false" disableUploadTimeout="true"
acceptCount="100" scheme="https" secure="true"
SSLEnabled="true"
SSLProtocol="TLSv1"
SSLCertificateFile="${catalina.base}/conf/localhost.crt"
SSLCertificateKeyFile="${catalina.base}/conf/localhost.key" />
