WebSphere MQ MQCONN Class resources are protected improperly.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-6962	ZWMQ0052	SV-7542r2_rule		Medium

Description
WebSphere MQ resources allow for the control of administrator functions, connections, commands, queues, processes, and namelists. Some resources provide the ability to disable or bypass security checking. Failure to properly protect WebSphere MQ resources may result in unauthorized access. This exposure could compromise the availability, integrity, and confidentiality of system services, applications, and customer data.
