IT08240| http://www-933.ibm.com/support/fixcentral/swg/selectFixes?parent=ibm~WebSphere&product=ibm/WebSphere/WebSphere+DataPower+XC10+Appliance&release=2.1.0.3&platform=All&function=all
Verify that applying this fix does not cause any compatibility issues. The fix disables RC4 stream cipher by default. If you change this setting you will expose yourself to the attack described above. 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.
For WebSphere DataPower XC10 Appliance Version 2.1 will need to apply the appropriate fix. This will disable the RC4 algorithm used on the appliance.
