Modified date:

Summary
The FREAK: Factoring Attack on RSA-EXPORT keys" TLS/SSL client and server
vulnerability may affect some configurations of WebSphere Application Server
used by WebSphere Service Registry and Repository.
Vulnerability Details
CVEID: CVE-2015-0138
DESCRIPTION: A vulnerability in various IBM SSL/TLS implementations could
allow a remote attacker to downgrade the security of certain SSL/TLS
connections. An IBM SSL/TLS client implementation could accept the use of an
RSA temporary key in a non-export RSA key exchange ciphersuite. This could
allow a remote attacker using man-in-the-middle techniques to facilitate
brute-force decryption of TLS/SSL traffic between vulnerable clients and
servers.
This vulnerability is also known as the FREAK attack.
CVSS Base Score: 4.3
CVSS Temporal Score: See
http://exchange.xforce.ibmcloud.com/#/vulnerabilities/100691 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)
Affected Products and Versions
WebSphere Service Registry and Repository versions 8.5, 8.0, 7.5, 7.0.
Workarounds and Mitigations
Please note that a default installed configuration of WebSphere Application
Server and WebSphere Service Registry and Repository uses a "STRONG" or "HIGH"
secure cipher list, which is not does not use RSA Export ciphers, so you would
not be affected if you have not changed your ciphers.
For advice on mitigating FREAK on servers which deviate from this default
configuration, please apply the mitigations indicated in the WebSphere
Application Server bulletin at
http://www-01.ibm.com/support/docview.wss?uid=swg21698613. You should verify
applying this configuration change does not cause any compatibility issues.

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.
