Summary
There are multiple vulnerabilities in current releases of the IBM SDK, Java
Technology Edition that affect IBM Tivoli Federated Identity Manager and IBM
Tivoli Federated Identity Manager Business Gateway. These issues were
disclosed as part of the IBM Java SDK updates in January 2016 and includes
the vulnerability commonly referred to as SLOTH.
Vulnerability Details
CVEID:
CVE-2016-0466
DESCRIPTION:
An unspecified vulnerability related to the JAXP 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/109948
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVEID:
CVE-2016-0448
DESCRIPTION:
An unspecified vulnerability related to the JMX component could allow a
remote attacker to obtain sensitive information.
CVSS Base Score: 4
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/109949
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:S/C:P/I:N/A:N)
CVEID:
CVE-2015-7575
DESCRIPTION:
The TLS protocol could allow weaker than expected security caused by a
collision attack when using the MD5 hash function for signing a
ServerKeyExchange message during a TLS handshake. An attacker could exploit
this vulnerability using man-in-the-middle techniques to impersonate a TLS
server and obtain credentials. This vulnerability is commonly known as
"SLOTH".
CVSS Base Score: 7.1
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/109415
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/UI:U/C:H/I:L/A:N)
Affected Products and Versions
Principal Product and Version(s) Affected Supporting Product and Version
IBM Tivoli Federated Identity Manager 6.2 IBM WebSphere Application Server 6.1
IBM Tivoli Federated Identity Manager Business Gateway 6.2
IBM Tivoli Federated Identity Manager 6.2.1 IBM WebSphere Application Server 6.1, 7.0
IBM Tivoli Federated Identity Manager Business Gateway 6.2.1
IBM Tivoli Federated Identity Manager 6.2.2 IBM WebSphere Application Server 6.1, 7.0, 8.0, 8.5
IBM Tivoli Federated Identity Manager Business Gateway 6.2.2
Remediation/Fixes
IBM Tivoli Federated Identity Manager and IBM Tivoli Federated Identity
Manager Business Gateway is affected through IBM WebSphere Application
Server. If you use one of the affected versions of WebSphere, update your IBM
WebSphere Application Server SDK with the appropriate Interim Fix based on
information in the WebSphere security bulletin
(Security Bulletin: Multiple vulnerabilities in IBM Java SDK affect WebSphere
Application Server January 2016 CPU (CVE-2016-0475, CVE-2016-0466,
CVE-2015-7575, CVE-2016-0448)).
Workarounds and Mitigations
For CVE-2015-7575:
Users of Java 7 and later can address the issue by updating the
/jre/lib/security/java.security file as follows (both steps are required):
Add MD5 to the jdk.certpath.disabledAlgorithms property - e.g.
jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024,
MD5
Add MD5withRSA to the jdk.tls.disabledAlgorithms property - e.g.
jdk.tls.disabledAlgorithms=SSLv3, RC4, DH keySize < 768,
MD5
Java 6 requires code changes in the JSSE component in addition to the
java.security file modifications, so upgrading the JDK is the only solution.
