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
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/97013
for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)
Affected products and versions
All versions of are IBM Flex System 40Gb Ethernet/IB6131 40Gb Infiniband Switch Firmware affected.
Remediation/Fixes:
None.
Workaround(s) & Mitigation(s):
You can help avoid this vulnerability by upgrading to firmware versions 3.3.4100 and later and restricted these products to use only TLS 1.2 by following the instructions here: The command is "web https ssl ciphers <ssl|TLS1.2>" Search for "web https" in the manual. After following these steps, connecting to the system will require a web browser that supports TLS 1.2. Firmware versions prior to 3.3.4100 do not allow you to restrict products to only using TLS 1.2.
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.
