Vulnerability Details CVE-ID: CVE-2014-8730 DESCRIPTION: Product could allow a remote attacker to obtain sensitive information, caused by the failure to check the contents of the padding bytes when using CBC cipher suites of some TLS implementations. A remote user with the ability to conduct a man-in-the-middle attack could exploit this vulnerability via a POODLE (Padding Oracle On Downgraded Legacy Encryption) like attack to decrypt sensitive information and calculate the plaintext of secure connections. CVSS Base Score: 4.3 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/99216 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N) Affected Products and Versions IBM SPSS Modeler 16.0 Remediation/Fixes None Workarounds and Mitigations For Windows: 1. Add one system environment variable GSK_STRICTCHECK_CBCPADBYTES=GSK_TRUE 2. Reboot the machine. For Linux/Unix: 1. Stop Modeler Server. 2. Edit modelersrv.sh to add following two lines, GSK_STRICTCHECK_CBCPADBYTES=GSK_TRUE export GSK_STRICTCHECK_CBCPADBYTES to export the environment variable. 3. Start Modeler Server. You should verify that applying this configuration change does not cause any compatibility issues.
