Workarounds and Mitigations
For the IBM XIV XCLI and XIV GUI, edit the file <install-dir>\jre\lib\security\java.security: change the last line to "jdk.tls.disabledAlgorithms=SSLv3, RC4". After editing and saving, restart the application.
For the IBM Hyper-Scale Manager, edit the file $JAVA_IBM_HOME/lib/security/java.security, where JAVA_IBM_HOME is by default /home/msms/hyperscale/jre, and change the last line to "jdk.tls.disabledAlgorithms=SSLv3, RC4". After editing and saving, restart the application.
You should verify applying this fix does not cause any compatibility issues. The fix disables RC4 stream cipher by default.
IBM recommends that you review your entire environment to identify other areas where you have enabled the RC4 stream cipher and take appropriate mitigation and remediation actions.
