Security Bulletin

Summary

The "FREAK: Factoring Attack on RSA-EXPORT keys" TLS/SSL client and server
vulnerability affects IBM WebSphere Application Server Full Profile (and IBM
WebSphere Application Server Hypervisor Edition) that is used by WebSphere
Process Server (and WebSphere Process Server Hypervisor Editions).

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 Process Server V7.0
    WebSphere Process Server Hypervisor Editions V6.2, V7.0

For earlier unsupported versions of the above products IBM recommends
upgrading to a fixed, supported version of the products.
