Security Bulletin: IBM Cloud Pak for Multicloud Management Monitoring is potentially vulnerable to execution of arbitrary code due to its use of Apache Log4j (CVE-2022-23302)

Security Bulletin

Summary

Apache Log4j is used by IBM Cloud Pak for Multicloud Management Monitoring as part of its logging infrastructure. Apache Log4j v1.2 has been removed and replaced by Log4j v2.17.1. Components that use Apache Log4j v1.2 are not exposed outside the cluster and are not configured to use the vulnerable Log4j v1 classes. Furthermore, it will take extraordinary measures by a malicious insider to attempt to reconfigure the components to be vulnerable.
