Affected Products and Versions
This vulnerability is known to affect the following offerings:
Affected IBM InfoSphere Master Data Management Server
|IBM InfoSphere Master Data Management||10.1|
|IBM InfoSphere Master Data Management||11.0|
|IBM InfoSphere Master Data Management||11.3|
|IBM InfoSphere Master Data Management||11.4|
|IBM InfoSphere Master Data Management||11.5|

The recommended solution is to apply the fix as soon as practical. Please see below for information on how to fix.
If you have customized the UI and you already have the source code available in RAD you can skip step#1 and #2.
1. Locate the com.ibm.mdm.sample.ba.webapp.ear.zip file from MDM sample.
2. Import the projects into RAD and follow Downloading, configuring and deploying the sample
3. Open web.xml from CustomerBusinessAdminWeb so
- enable com.sun.faces.enableHighAvailability in Web.xml
Refer the code below
If set to true while server-side state saving is being used, a serialized representation
of the view is stored on the server. This allows for failover and sever clustering support.
Default is false. This parameter is not available in JSF 1.0.</description>
- After the code changes do build all
4. Export CustomerBusinessAdmin as EAR
Then From RAD, File -> Export -> Ear File (Under Java EE)
in EAR Export wizard
- select EAR Project name as 'CustomerBusinessAdmin'
- Then provide the destination , that earfile name
5. Deploy the this new exported EAR on server
Note: Before installing EAR on server make sure ClientAuthentication.properties and mdmUIConfiguration.properties of propertiesUI.jar have valid connection properties.
