2. Review the Remediation/Fixes section in the Security Bulletin: Information disclosure in WebSphere Application Server Liberty (CVE-2018-1755) for available fixes in the version that you are using.
3. Review the Security Bulletin: Information disclosure in WebSphere Application Server Liberty (CVE-2018-1755) for vulnerability details.
   * When installing the fixed WAS Liberty package use <JazzInstallLocation>/server/liberty/wlp as the location of the WAS Liberty installation, where <JazzInstallLocation> is the root folder of your CLM installation
