CVEID: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. The IBM SDK for Java Technology Edition has changed the default to eliminate the POODLE vulnerability. There is a new system property com.ibm.jsse2.disableSSLv3 It is defaulted to true so that it will not use SSLv3. If you want to take the risk you may turn SSLv3 back on with the system property: com.ibm.jsse2.disableSSLv3=false

CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/97013 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)

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. You should verify disabling SSLv3 does not cause any compatibility issues.
