Security Bulletin: Multiple vulnerabilities in IBM Java SDK affect IBM SPSS Collaboration and Deployment Services (CVE-2015-0478, CVE-2015-0488, CVE-2015-2808, CVE-2015-4000)

Summary

There are multiple vulnerabilities in IBM SDK Java Technology Edition, Versions 1.6 and 1.7 that are used by IBM SPSS Collaboration and Deployment Services. These issues were disclosed as part of the IBM Java SDK updates in April 2015 and IBM Java SDK update addressing TLS protocol vulnerability involving DHE_EXPORT ciphersuite commonly referred as “logjam attack.”

Vulnerability Details

CVEID: CVE-2015-0478 DESCRIPTION: An unspecified vulnerability in Oracle Java SE and JRockit related to the JCE component could allow a remote attacker to obtain sensitive information.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/102339 for the current score

CVEID: CVE-2015-0488 DESCRIPTION: An unspecified vulnerability in Oracle Java SE and Jrockit related to the JSSE component could allow a remote attacker to cause a denial of service.
CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/102336 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

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

CVEID: CVE-2015-4000**
DESCRIPTION:** The TLS protocol could allow a remote attacker to obtain sensitive information, caused by the failure to properly convey a DHE_EXPORT ciphersuite choice. An attacker could exploit this vulnerability using man-in-the-middle techniques to force a downgrade to 512-bit export-grade cipher. Successful exploitation could allow an attacker to recover the session key as well as modify the contents of the traffic. This vulnerability is commonly referred to as “Logjam”.
CVSS Base Score: 4.3

Remediation/Fixes

Product

| VRMF| APAR| Remediation/First Fix
—|—|—|—
SPSS Collaboration and Deployment Services| 4.2.1| PI43535| 4.2.1
SPSS Collaboration and Deployment Services| 5.0| PI43535| 5.0

You should verify applying this fix does not cause any compatibility issue in your environment.

If you change the default setting after applying the fix, 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 Diffie-Hellman key-exchange protocol used in TLS and take appropriate mitigation and remediation actions.
