ClearQuest Web/CQ OSLC Server/CM Server Component

1. 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.
2. Review the following WAS security bulletin:
