Vulnerability Details

CVE-2015-0204 was fixed in IBM SDK, Java Technology Edition under CVE-2015-0138. Both CVEs are included in this advisory for completeness.

CVEID:CVE-2015-0488**
DESCRIPTION:*An unspecified vulnerability 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&gt;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 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&gt;for the current score
CVSS Environmental Score: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)

CVEID:CVE-2015-0204**
DESCRIPTION:*A vulnerability in the OpenSSL ssl3_get_key_exchange function could allow a remote attacker to downgrade the security of certain TLS connections. An OpenSSL client accepts the use of an RSA temporary key in a non-export RSA key exchange ciphersuite. This could allow a remote attacker using man-in-the-middle techniques to facilitate brute-force decryption of TLS/SSL traffic between vulnerable clients and servers. This vulnerability is also known as the FREAK attack.
CVSS Base Score: 4.3
CVSS Temporal Score: See<https://exchange.xforce.ibmcloud.com/vulnerabilities/99707&gt;for the current score
CVSS Environmental Score: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/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&gt;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&gt;for the current score
CVSS Environmental Score: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID:CVE-2015-0138**
DESCRIPTION:*A vulnerability in various IBM SSL/TLS implementations could allow a remote attacker to downgrade the security of certain SSL/TLS connections. An IBM SSL/TLS client implementation could accept the use of an RSA temporary key in a non-export RSA key exchange ciphersuite. This could allow a remote attacker using man-in-the-middle techniques to facilitate brute-force decryption of TLS/SSL traffic between vulnerable clients and servers. This vulnerability is also known as the FREAK attack.

Affected Products and Versions

The following IBM Java versions are affected:

• IBM SDK, Java 2 Technology Edition, Version 5.0 Service Refresh 16 Fix Pack 9 and earlier releases
• IBM SDK, Java Technology Edition, Version 6 Service Refresh 16 Fix Pack 3 and earlier releases

• IBM SDK, Java Technology Edition, Version 8 GA **

IBM supplied the Java Runtime Environment (JRE) from the IBM SDK Java Technology Edition Versions with the following:

The 7.1.x versions of Maximo Asset Management, Maximo Asset Management Essentials, Maximo Asset Management for Energy Optimization, Maximo for Government, Maximo for Nuclear Power, Maximo for Transportation, Maximo for Life Sciences, Maximo for Oil and Gas, Maximo for Utilities, Tivoli Asset Management for IT, Tivoli Service Request Manager, and Tivoli Change and Configuration Management Database bundled the JRE from IBM SDK Java 2 Technology Edition Version 5.

The 7.2.x versions of Tivoli Asset Management for IT, Tivoli Service Request Manager, and Tivoli Change and Configuration Management Database bundled the JRE from IBM SDK Java 2 Technology Edition Version 5.

The 7.5.x versions of Maximo Asset Management, Maximo Asset Management Essentials, Maximo for Government, Maximo for Nuclear Power, Maximo for Transportation, Maximo for Life Sciences, Maximo for Oil and Gas, Maximo for Utilities, and SmartCloud Control Desk bundled the JRE from IBM SDK Java Technology Edition Version 6.

The 7.6.x versions of Maximo Asset Management bundled the JRE from IBM SDK Java Technology Edition Version 7.

TRIRIGA for Energy Optimization 1.1.x bundled the JRE from IBM SDK Java Technology Edition Version 6.

It is likely that earlier unsupported versions are also affected by these vulnerabilities. Remediation is not provided for product versions that are no longer supported. IBM recommends that customers running unsupported versions upgrade to the latest supported version of products in order to obtain remediation for the vulnerabilities.

Remediation/Fixes

There are two areas where the vulnerabilities in the Java SDK/JDK or JRE may require remediation:

1. Application Server – Update the Websphere Application Server. Refer to JDK Fixes for Websphere Application Server for additional information on updating and maintaining the JDK component within Websphere. Customers with Oracle Weblogic Server, which is not an IBM product and is not shipped by IBM, will also want to update their server.
2. Browser Client - Update the Java plug-in used by the browser on client systems, using the remediated JRE version referenced on developerWorks JavaTM Technology Security Alerts or referenced on Oracle’s latest Critical Patch Update (which can be accessed via developerWorks JavaTM Technology Security Alerts). Updating the browser Java plug-in may impact some applets such as Maximo Asset Management Scheduler. Download from IBM FixCentral the latest Maximo Asset Management Scheduler Interim Fix for Version 7.1 or Maximo Asset Management Fix Pack for Version 7.5.0.2 or later, which includes the resolution for APAR IV11560.

Due to the threat posed by a successful attack, IBM strongly recommends that customers apply fixes as soon as possible.

Workarounds and Mitigations

Until you apply the fixes, it may be possible to reduce the risk of successful attack by restricting network protocols required by an attack. For attacks that require certain privileges or access to certain packages, removing the privileges or the ability to access the packages from unprivileged users may help reduce the risk of successful attack. Both approaches may break application functionality, so IBM strongly recommends that customers test changes on non-production systems. Neither approach should be considered a long-term solution as neither corrects the underlying problem.

Mitigation instructions for CVE-2015-2808 are available here:

• IBM SDK, Java Technology Edition, Version 8

• IBM SDK, Java Technology Edition, Version 7R1
• IBM SDK, Java Technology Edition, Version 7

No equivalent mitigation is available for IBM SDK, Java Technology Edition, Version 6, and IBM SDK, Java 2 Technology Edition, Version 5.0.
