Workarounds and Mitigations
Manual Procedure to Update the Help system
The Help system shipped along with the Operations Center includes the affected log4j versions. To manually update the Help system:
1. Download the following from Apache:
Apache Log4j 2 binary(zip) apache-log4j-2.16.0-bin.zip
https://logging.apache.org/log4j/2.0/download.html
2. Stop the Operations Center service (which also stops the Help system)
AIX - /opt/tivoli/tsm/ui/utils/stopserver.sh
Linux -
8.1.9 and Lower (including v7) - service opscenter.rc stop
8.1.10 and higher - systemctl stop opscenter.service
Windows - From the Services window, stop the IBM Spectrum® Protect Operations Center service.
4. Unzip the apache-log4j-2.16.0-bin.zip
5. From the unzipped directory apache-log4j-2.16.0-bin copy the log4j2.16 jars and remove the earlier ones
6. From
AIX and Linux - /opt/tivoli/tsm/ui/Liberty/usr/servers/guiServer/apps/TSM_HELP.war/WEB-INF/lib/
Windows - c:\Program Files\Tivoli\TSM\\ui\Liberty\usr\servers\guiServer\apps/TSM_HELP.war/WEB-INF/lib\
Replace:
log4j-api-2.8.2.jar
log4j-1.2-api-2.8.2.jar
log4j-core-2.8.2.jar
log4j-slf4j-impl-2.8.2.jar
with
log4j-api-2.16.0.jar
log4j-1.2-api-2.16.0.jar
log4j-core-2.16.0.jar
log4j-slf4j-impl-2.16.0.jar
7. Restart OC service
AIX - /opt/tivoli/tsm/ui/utils/startserver.sh
Linux -
8.1.9 and Lower (including v7) - service opscenter.rc start
8.1.10 and higher - systemctl start opscenter.service
Windows - From the Services window, start the IBM Spectrum® Protect Operations Center service.
