Workarounds and Mitigations
IBM Support Assistant is configured with a basic user registry to support authentication and authorization for access to the Administration console. For details on how to change the configuration refer to the Securing Communications section of the IBM Support Assistant Team Server Knowledge Center.
An “ssl” element can be added so the default ssl configuration will not use SSLv3. The sslProtocol attribute in the ssl element defines what protocol is used. Setting it to TLS will override the default.
- Open a command prompt, then change directory to the <isa_install>/ISA5/wlp/usr/servers/isa directory.
- Open the server.xml file with a text editor
- Add "ssl" element
<ssl id="defaultSSLConfig"
keyStoreRef="defaultKeyStore"
sslProtocol="TLS" />
Refer to the Security Bulletin for WebSphere Application Server Liberty Profile for details.
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.
