Workarounds and Mitigations
Direct the GUI's Liberty profile webserver to disable use of the SSLv3 and older protocols. This is done by editing the webserver configuration to set the minimum protocol to be Transport Layer Security (TLS) 1.0.
Use the following procedure to edit the webserver configuration:
1. Locate the file server.xml in its current directory:
Windows: C:\IBM\tivoli\tsm\tdpvmware\webserver\usr\servers\veProfile
Linux: /opt/tivoli/tsm/tdpvmware/common/webserver/usr/servers/veProfile
2. Edit the server.xml file with a text editor as follows:
a) Locate the existing line that starts with <keyStore id="defaultKeyStore" ...
b) Insert the following 2 lines below it:
<ssl id="veSSLConfig" sslProtocol="TLS" keyStoreRef="defaultKeyStore"/>
<sslDefault sslRef="veSSLConfig"/>
c) Save the changes to server.xml
3. In same directory as server.xml, save the jvm.options file that is attached to this bulletin and located after the Disclaimer.
4. Restart the webserver as follows:
Windows:
a. Click Start > Control Panel > Administrative Tools > Services
b. Right-click Data Protection for VMware Web Server Service and click Restart
Linux: Issue the following command as root:
service webserver restart
The GUI is now operational with SSLv3 and older protocols disabled.
IBM recommends that you review your entire environment to identify areas that enable the SSLv3 protocol and take appropriate mitigation and remediation actions. The most immediate mitigation action that can be taken is disabling SSLv3. You should verify disabling SSLv3 does not cause any compatibility issues.
