Vulnerability Details
CVEID: CVE-2016-2183
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error in the DES/3DES cipher, used as a part of the SSL/TLS protocol. By capturing large amounts of encrypted traffic between the SSL/TLS server and the client, a remote attacker able to conduct a man-in-the-middle attack could exploit this vulnerability to recover the plaintext data and obtain sensitive information. This vulnerability is known as the SWEET32 Birthday attack.

Affected Products and Versions
IBM Application Delivery Intelligence 1.0.1, 1.0.1.1, and 1.0.2
Remediation/Fixes
Customers need to do the following to apply the fix:
1. Stop the server. Navigate to the unzipped-archive/adi/server directory and run this script: server.shutdown
2. Delete jre directory from unzipped-archive/server/jre
3. Download ibm-java-jre-7.1-4.1, unzip it and copy the jre directory to unzipped-archive/server (you are providing the jre directory that you deleted in step 2).

4. Navigate to the unzipped-archive/adi/server directory, open server.startup script using prefered text editor (e.g., Notepad for Windows or Vim Editor for Linux) and add one more option to the healthcenter parameter set:
Windows:
Modify the line numbered 125 (where HEALTHCENTER_OPTS parameter located) by adding a new healthcenter option:
-Dsun.rmi.registry.registryFilter=javax.rmi.CORBA.Stub
Before modification:
set HEALTHCENTER_OPTS=-agentlib:healthcenter -Dcom.ibm.java.diagnostics.healthcenter.agent.port=1972
After modification:
set HEALTHCENTER_OPTS=-agentlib:healthcenter -Dcom.ibm.java.diagnostics.healthcenter.agent.port=1972 -Dsun.rmi.registry.registryFilter=javax.rmi.CORBA.Stub
Linux:
Modify the line numbered 157 (where HEALTHCENTER_OPTS parameter located) by adding a new healthcenter option:
-Dsun.rmi.registry.registryFilter=javax.rmi.CORBA.Stub
Before modification:
export HEALTHCENTER_OPTS="-agentlib:healthcenter -Dcom.ibm.java.diagnostics.healthcenter.agent.port=1972"
After modification:
export HEALTHCENTER_OPTS="-agentlib:healthcenter -Dcom.ibm.java.diagnostics.healthcenter.agent.port=1972
-Dsun.rmi.registry.registryFilter=javax.rmi.CORBA.Stub"
Note, if the line numbers are not exactly matched, search parameter -Dcom.ibm.java.diagnostics.healthcenter.agent in server.startup script to find the line containing the health center parameter.
5. Start the server. Navigate to the unzipped-archive/adi/server directory and run this script: server.startup
