Security Bulletin: IBM Edge Application Manager is vulnerable to arbitrary code execution due to Apache Log4j (CVE-2021-44228)

Summary

IBM Edge Application Manager (IEAM) 4.3.0 has a dependency on IBM Cloud Pak Foundational Services (IBM Common Services) which includes an unused Operator that contains a vulnerable version of Apache Log4j as described in CVE-2021-44228. An upgrade has been released which includes Apache Log4j version 2.15.0 to address this vulnerability.

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.

Affected Products and Versions

Remediation/Fixes

IBM strongly recommends addressing this vulnerability now by upgrading.

By default subscriptions to the IBM Edge Application Manager (IEAM)operator and its dependent operands are set   
to automatic approval for its update channel. This means that new releases of IEAM or its dependencies for the   
configured channel will be automatically applied.

Note:  A Cluster Administrator can set the approval strategy to Manual. In this case   
a Cluster Administrator will need to manually approve pending changes.

Otherwise, the latest version of IBM Cloud Pak Foundational Services (3.6.7) 
has been released and all IBM Edge Application Manager 4.3.0 instances will be
upgraded automatically without user-intervention if automatic updates are 
enabled.
