Vulnerability Details CVEID: CVE-2015-2808 DESCRIPTION: The RC4 algorithm, as used in the TLS protocol and SSL protocol, could allow a remote attacker to obtain sensitive information. An attacker could exploit this vulnerability to remotely expose account credentials without requiring an active man-in-the-middle session. Successful exploitation could 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 Optim Performance Manager for DB2 on Linux, UNIX, and Windows version 4.1 through 4.1.1 IBM InfoSphere Optim Performance Manager for DB2 on Linux, UNIX, and Windows version 5.1 through 5.3.1 Remediation/Fixes OPM Version Download URL 4.1 126.96.36.199 No fix available yet 5.2 5.3 No fix available yet, see Workarounds and Mitigations 5.3.1 Fix Central (Interim Fix 8409) or see Workarounds and Mitigations For OPM versions 4.1 through 188.8.131.52, an IBM Java fix will be made available by April 27, 2015. We will update this Security Bulletin when the IBM Java fixes are available. For OPM versions 5.2 through 5.3, until the IBM Java fix will be made available by April 27, 2015, follow the Workarounds and Mitigation section below. For OPM version 5.3.1, installing the OPM Interim Fix changes the Java Security configuration of the web console server to disallow RC4 cipher suites for HTTPS connections (using the SSL/TLS protocol). If you are not able to install the OPM Interim Fix, follow the Workarounds and Mitigation section below. Workarounds and Mitigations For OPM versions 5.2 through 5.3.1 disable the RC4 cipher suite by adding "RC4" to the list of disabled algorithms defined by the jdk.tls.disabledAlgorithms security property in java.security file. Edit the java.security file that is located in the InfoSphere Optim Performance Manager installation directory: /jre/lib/security/java.security Add the following line and save the file: jdk.tls.disabledAlgorithms=RC4 If the jdk.tls.disabledAlgorithms property was already enabled (without a "#" character at the beginning of the line), i.e.: jdk.tls.disabledAlgorithms=SSLv3 then append the text ", RC4" to the end of the line and save the file. jdk.tls.disabledAlgorithms=SSLv3, RC4 Restart the OPM Web Console server for this change to take effect. You should verify applying this configuration change does not cause any compatibility issues. Not disabling the RC4 stream cipher 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.
