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. Remediation/Fixes Please consult the security bulletin Security Bulletin: Vulnerability with RSA Export Keys may affect IBM WebSphere Application Server (CVE-2015-0138) for vulnerability details and information about fixes.
