Security Bulletin
Summary
Log4J is used by IBM App Connect Enterprise Certified Container for logging when generating a bar file that contains a JDBC connector and when running a flow that contains a JDBC connector. IBM App Connect Enterprise Certified Container Designer Authoring operands and Integration Server operands that use the JDBC connector may be vulnerable to remote code execution due to CVE-2021-44228. This bulletin provides patch information to address the reported Log4j vulnerability (CVE-2021-44228).
Vulnerability Details
CVEID: CVE-2021-44228
DESCRIPTION: Apache Log4j could allow a remote attacker to execute arbitrary code on the system, caused by the failure to protect against attacker controlled LDAP and other JNDI related endpoints by JNDI features. By sending a specially crafted code string, an attacker could exploit this vulnerability to load arbitrary Java code on the server and take complete control of the system.
Note: The vulnerability is also called Log4Shell or LogJam.

Remediation/Fixes
IBM strongly recommends addressing the vulnerability now by upgrading the operator and any DesignerAuthoring and IntegrationServer operands .
App Connect Enterprise Certified Container 1.4, 1.5, 2.0, 2.1 and 3.0 (Continuous Delivery)
Upgrade to App Connect Enterprise Certified Container Operator version 3.1.0 or higher, and ensure that all DesignerAuthoring and IntegrationServer components are at 12.0.3.0-r1 or higher. Documentation on the upgrade process is available at https://www.ibm.com/docs/en/app-connect/containers_cd?topic=releases-upgrading-operator
Alternatively you can update the operator version to 3.0.0 or higher, then apply a set of iFix images for the DesignerAuthoring and IntegrationServer operands. Instructions on upgrading the Operator and applying the iFix images for the Continuous Delivery release are available at https://www.ibm.com/support/pages/node/6527178
App Connect Enterprise Certified Container 1.1 EUS (Extended Update Support)
Upgrade to App Connect Enterprise Certified Container Operator version 1.1.5 or higher, and ensure that all DesignerAuthoring and IntegrationServer components are at 11.0.0.15-r1-eus or higher. Documentation on the upgrade process is available at https://www.ibm.com/docs/en/app-connect/containers_eus?topic=releases-upgrading-operator
Alternatively you can update to Operator version 1.1.4 or higher, then apply a set of iFix images for the DesignerAuthoring and IntegrationServer operands. Instructions on upgrading the Operator and applying the iFix images for the Continuous Delivery release are available at https://www.ibm.com/support/pages/node/6527180
Note: For other versions prior to 1.4 IBM strongly recommends upgrading to a supported level and following the instructions above for the Continuous Delivery versions
