Affected Products and Versions
Rational Test Control Panel component in Rational Test Virtualization Server and Rational Test Workbench versions:
- All 8.0.x
- All 8.5.0.x
Versions 8.5.1 and later are unaffected as they do not use Apache Tomcat.
Remediation/Fixes
The fixes for the CVEs mentioned above have been incorporated into the 7.0.54 release of Apache Tomcat. You should upgrade your installation by following the instructions below.
- Download the fix for your product from Fix Central:
- Rational Test Workbench - 7.0.54-Rational-RTW-Tomcat-zip
- Rational Test Virtualization Server - 7.0.54-Rational-RTVS-Tomcat-zip
- Unzip the downloaded file to a directory.
- Stop the server.
- In the existing RTCP installation, save the files logging.properties and server.xml to a separate location.
The default installation locations for these files are: - Windows: C:\Program Files\IBM\RationalTestControlPanel\conf\
- AIX, Linux, Solaris: /opt/IBM/RationalTestControlPanel/conf/
- Copy the contents of the unzipped Tomcat directory (except for the LICENSE file) into the RationalTestControlPanel directory, overwriting the existing files.
- Copy the two configuration files you saved earlier back into /conf.
- Start the server.
Notes:
- When updating an installation to a later version of Rational Test Control Panel, the security fix detailed above will have to be re-applied after the RTCP update
- When removing an installation that has had the security fix applied, not all the files will be removed by IBM Installation Manager, and some files will have to be removed manually.
