Remediation/Fixes

The recommended solution is to apply the Interim Fix (iFix) or Cumulative Fix (CF) containing APAR JR58572 as soon as practical:


IBM Business Process Manager also needs JR58611:

WebSphere Application Server is shipped as a component of IBM Business Process Manager, WebSphere Process Server and WebSphere Enterprise Service Bus. WebSphere Application Server Liberty is shipped as a component of the optional BPM component Process Federation Server. Please consult the security bulletin

for vulnerability details and information about fixes for WebSphere Application Server and WebSphere Application Server Liberty.

Because IBM Business Process Manager V7.5, V8.0 and WebSphere Process Server V7.0 are out of general support, fixes for V7.0, V7.5, V8.0 for these products and WebSphere Enterprise Service Bus V7.0 and V7.5 and WebSphere Enterprise Service Bus Registry Edition V7.0 and V7.5 can be requested from IBM support by eligible customers.
