✅ Remediation

For OpenShift Container Platform 4.8 see the following documentation, which will be updated shortly for this release, for important instructions on how to upgrade your cluster and fully apply this errata update: https://docs.openshift.com/container-platform/4.8/release_notes/ocp-4-8-release-notes.html For Red Hat OpenShift Logging 5.2, see the following instructions to apply this update: https://docs.openshift.com/container-platform/4.7/logging/cluster-logging-upgrading.html Workaround: For Log4j 2 versions up to and including 2.16.0, this flaw can be mitigated by: - In PatternLayout in the Log4j logging configuration, replace Context Lookups like ${ctx:loginId} or $${ctx:loginId} with Thread Context Map patterns (%X, %mdc, or %MDC) like %X{loginId}. - Otherwise, in the Log4j logging configuration, remove references to Context Lookups like ${ctx:loginId} or $${ctx:loginId} where they originate from sources external to the application such as HTTP headers or user input.
