ClearQuest Web/CQ OSLC Server/CM Server Component
- Determine the WAS version used by your CM server. Navigate to the CM profile directory (either the profile you specified when installing ClearQuest, or <clearquest-home>/cqweb/cqwebprofile), then execute the script: bin/versionInfo.sh (UNIX) or bin\versionInfo.bat (Windows). The output includes a section "IBM WebSphere Application Server". Make note of the version listed in this section.
- Review the following WAS security bulletin:
Security Bulletin: Multiple Vulnerabilities in IBM® Java SDK affect WebSphere Application Server January 2020 CPU
and apply the latest available fix for the version of WAS used for CM server.
Note: there may be newer security fixes for WebSphere Application Server. Follow the link above (in the section "Get Notified about Future Security Bulletins") to subscribe to WebSphere product support alerts for additional Java SDK fixes.
