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.
