====== Spectrum Scale errors ======

===== Log4J =====

Problem Determination: 

Determine if you are using any of the versions of IBM Spectrum Scale or ESS impacted by this vulnerability.

Workaround/Mitigation:

Customers are advised to edit the file /etc/sysconfig/gpfsgui on each node running the GUI to include a line like this

LOG4J_FORMAT_MSG_NO_LOOKUPS=true

Final file content should look similar to this example:
<cli ptompt='$'>
$ cat /etc/sysconfig/gpfsgui

# mitigation for log4j issue
LOG4J_FORMAT_MSG_NO_LOOKUPS=true

# IP tables
UPDATE_IPTABLES=true

# Setup iptables rules only on these (comma separated) interfaces
UPDATE_IPTABLES_INTERFACES=
GUI_HTTP_PORT=80
GUI_HTTPS_PORT=443
</cli>

After the file has been changed for each node running the GUI , the GUI process must be restarted, by issuing the command "systemctl restart gpfsgui".

Note: 

    For the IBM Spectrum Scale on AWS Marketplace version "Spectrum Scale 5.0.5.3 BYOL v1.3.1", the IBM Spectrum Scale GUI is not started by default. If the IBM Spectrum Scale GUI was started either using the "mmcloudworkflows gui_service start" command or manually, login to the node on which the IBM Spectrum Scale GUI is running and follow the steps detailed above.
    For IBM Spectrum Scale Container Native Storage Access environments, a fix will be made available on Github  (https://github.com/IBM/ibm-spectrum-scale-container-native) which will pull updated images via IBM Cloud Container Registry.  In the meantime, to help mitigate the risk, customers should patch the GUI statefulset and set the LOG4J_FORMAT_MSG_NO_LOOKUPS="true" environment variable to force this change:
        For CNSA v5.1.1.3, v5.1.1.4, v5.1.2.1:  oc set env -c liberty -e LOG4J_FORMAT_MSG_NO_LOOKUPS=true sts/ibm-spectrum-scale-gui -nibm-spectrum-scale
        For CNSA v5.1.1.1: oc set env -c liberty -e LOG4J_FORMAT_MSG_NO_LOOKUPS=true sts/ibm-spectrum-scale-gui -nibm-spectrum-scale-ns
