Security Bulletin: Multiple vulnerabilities in IBM Java SDK affect IBM Emptoris Strategic Supply Management, and IBM Emptoris Services Procurement.

Summary

The IBM Emptoris Strategic Supply Management Suite and IBM Emptoris Services Procurement products are affected by multiple security vulnerabilities that exist in IBM SDK Java Technology Edition that is shipped with IBM WebSphere Application Server. The security bulletin includes issues disclosed as part of the IBM Java SDK updates in April 2015.

Vulnerability Details

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-2015-0478**
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
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)

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)

CVEID: CVE-2015-1916**
DESCRIPTION:** Server applications which use the IBM Java Secure Socket Extension provider to accept SSL/TLS connections are vulnerable to a denial of service attack due to an unspecified vulnerability.
CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101995 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID: CVE-2015-4000**
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
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/103294 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 Emptoris Contract Management 9.5 through 10.0.4
IBM Emptoris Program Management 10.0.0 through 10.0.4
IBM Emptoris Sourcing 10.0.0 through 10.0.4
IBM Emptoris Spend Analysis 10.0.0 through 10.0.4

Remediation/Fixes

An interim fix has been issued for the IBM WebSphere Application Server (WAS) which will upgrade the IBM Java Development Kit to a version which is not susceptible to this vulnerability. Customers running any of the IBM Emptoris products listed above should apply the interim fix to all IBM WebSphere Application Server installations that are used to run IBM Emptoris applications. See Multiple vulnerabilities in IBM® Java SDK affect WebSphere Application Server April 2015 CPU and Vulnerability with Diffie-Hellman ciphers may affect IBM WebSphere Application Server (CVE-2015-4000) for more details on upgrade versions.

Select the appropriate WebSphere Application Server fix based on the version being used for IBM Emptoris product version. The following table lists the IBM Emptoris application versions along with the corresponding required version of IBM WebSphere Application Server and a link to the corresponding fix version where further installation instructions are provided.

Workarounds and Mitigations

The Logjam attack which affects TLS connections using the Diffie-Hellman (DH) key exchange protocol may affect some configurations in WebSphere Application Server.

WebSphere Application Server has DH and DHE ciphers included in the “STRONG” or “HIGH”, “MEDIUM” and “LOW” cipher lists. They also could be present if you have a “CUSTOM” list of ciphers. You will need to remove any of the ciphers that begin with SSL_* or TLS_* that also have DH or DHE in the Name from your WebSphere Application Server SSL configuration. This does NOT include ciphers that have ECDH or ECDHE in the Name, these are elliptic curve Diffie-Hellman ciphers and they are not affected.

Disclaimer

According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an “industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response.” IBM PROVIDES THE CVSS SCORES ““AS IS”” WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. “Affected Products and Versions” referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
