An attacker can exploit this vulnerability to remotely expose account credentials without requiring an active man-in-the-middle session. Successful exploitation might allow an attacker to retrieve credit card data or other sensitive information. This vulnerability is commonly referred to as "Bar Mitzvah Attack". CVSS Base Score: 5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101851 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N) Affected Products and Versions IBM Decision Optimization Center: v3.8 and earlier Remediation/Fixes The recommended solution is to download and install IBM Java SDK version 6 Service Refresh 16 Fix Pack 3 with fixes for CVE-2015-0138 (FREAK) and CVE-2015-2808 (Bar Mitzvah) as soon as practicable. Before installing a newer version of IBM Java SDK, ensure that you: Close any open programs that you have running; Rename the initial directory of the IBM Java SDK (for example: with .old at the end), Download and install IBM Java SDK version 6 Service Refresh 16 Fix Pack 3 or later from Fix Central Check the build number with the command "java -version". The fix is correctly installed if the build number is equal to pwa6460sr16fp3ifix-20150407_01(SR16 FP3+IV70681+IV71888). You must verify that applying this fix does not cause any compatibility issues. The fix disables RC4 stream cipher by default. If you change this setting you will expose yourself to the attack described above. IBM recommends that you review your entire environment to identify other areas where you have enabled the RC4 stream cipher and take appropriate mitigation and remediation actions. Further information is available about this vulnerability in Websphere Application Server and here are the detailed instructions for updating IBM Java SDK.
