Note:
As a result of the CVE CVE-2016-2183 vulnerability the cryptographic algorithm 3DES_EDE_CBC is no longer considered secure. Installing any of the above fixes or altering the below configuration will disable all uses of the 3DES_EDE_CBC algorithm through Java. Any cipher suite used during TLS handshaking which tries to use 3DES_EDE_CBC is not accepted.
Workarounds and Mitigations
For CVE-2016-2183:
Users can address the issue by updating the java.security file to disable the use of the 3DES_EDE_CBC algorithm.
1. Edit the java.security file in the jre/lib/security directory of the IBM Integration Bus or WebSphere Message Broker installation.
For example:
v10:
c:\Program Files\IBM\IIB\10.0.0.2\common\jdk\jre\lib\security\java.security
/opt/ibm/iib/10.0.0.2/common/jdk/jre/lib/security/java.security (LinuxX64 only)
/opt/ibm/iib/10.0.0.2/common/jre/lib/security/java.security
v9 & v8 (@ 8.0.0.7 or later):
c:\Program Files\IBM\MQSI\9.0.0.4\jre17\lib\security\java.security
/opt/ibm/mqsi/9.0.0.4/jre17/lib/security/java.security
c:\Program Files\IBM\MQSI\8.0.0.6\jre17\lib\security\java.security
/opt/ibm/mqsi/8.0.0.6/jre17/lib/security/java.security
2. Add DESede to the jdk.tls.disabledAlgorithms property
For example:
jdk.tls.disabledAlgorithms=SSLv3, RC4, DH keySize < 768, MD5withRSA, DESede
