mtnbill the vulnerability CVE-2021-44832 is described on the Apache Log4J web site as:
Apache Log4j2 vulnerable to RCE via JDBC Appender when attacker controls configuration
If the attacker controls the configuration of logging on your Jenkins controller, they are already an administrator on that Jenkins controller. They can perform many operations as an administrator. Altering the logging configuration is the least of your concerns if an attacker has become an administrator on your Jenkins controller.
You're certainly welcome to press MicroFocus to update the plugin to use a newer version of Apache Log4j2, but I suspect that the upgrade from 2.17.0 to 2.17.2 will not change the actual risk to your Jenkins controller. It may satisfy scanners that can only check for the presence of a library version, but won't provide much more than that.
Micro Focus Application Automation Tools Plugin 7.2 fixed
JENKINS-67357by upgrading to log4j 2.17.0. https://logging.apache.org/log4j/2.x/security.html says log4j 2.17.1 fixes "CVE-2021-44832: Apache Log4j2 vulnerable to RCE via JDBC Appender when attacker controls configuration."
