Vulnerability Details Please consult the Security Bulletin: Vulnerability with RSA Export Keys may affect IBM WebSphere Application Server (CVE-2015-0138) for vulnerability details and information about fixes. 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 IBM Rational RequisitePro, RequisiteWeb Server component. Version 7.1.3.x, 7.1.4.x Status This vulnerability only applies to RequisiteWeb component, and it only applies if one of the following conditions exist: - - You have installed RequisiteWeb server into an existing WAS profile, and that profile supports a non-default set of ciphers. - - You modified the default set of ciphers in the WAS profile created during the installation of RequisitePro. Version 7.1.0.x, 7.1.1.x, 7.1.2.x Status This vulnerability only applies to the RequisiteWeb component, other parts of RequisitePro are not affected. In addition, this vulnerability only applies if you modified the RequisiteWeb WAS profile by changing its set of supported ciphers. Remediation/Fixes Review the security bulletin referenced above and apply the relevant fixes to your WAS installation and WAS profiles used for RequisiteWeb. Affected version Applying the fix 7.1.3.x, 7.1.4.x Apply the appropriate WebSphere Application Server directly to your RequisiteWeb server host. No particular RequisitePro steps are necessary. 7.1.0.x, 7.1.1.x and Document 1390803 explains how to update 7.1.2.x WebSphere Application Server for RequisiteWeb servers for 7.1.0.x, 7.1.1.x and 7.1.2.x releases.
