Vulnerability discussion

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.

a) Refer to the following report produced by the ACF2 Data Collection and Data Set and Resource Data Collection: - SENSITVE.RPT(MQADMIN) - ACF2CMDS.RPT(RESOURCE) – Alternate report Automated Analysis Refer to the following report produced by the Data Set and Resource Data Collection: - PDI(ZWMQ0060) b) Ensure the following items are in effect: NOTE: ssid is the queue manager name (a.k.a., subsystem identifier). 1) A RESLEVEL resource (i.e., ssid.RESLEVEL) is defined for each queue manager to TYPE(MQA) (i.e., MQADMIN resource class) with a default access of PREVENT. 2) Access authorization to these RESLEVEL resources restricts all access. No users are permitted access to ssid.RESLEVEL resources. c) If both of the items in (b) are true, there is NO FINDING. d) If either item in (b) is untrue, this is a FINDING.

Fix text

The IAO will ensure that a ssid.RESLEVEL profile is only defined for each queue manager. Ensure the following items are in effect: NOTE: ssid is the queue manager name (a.k.a., subsystem identifier). 1) A RESLEVEL resource (i.e., ssid.RESLEVEL) is defined for each queue manager to TYPE(MQA) (i.e., MQADMIN resource class) with a default access of PREVENT. 2) Access authorization to these RESLEVEL resources restricts all access. No users are permitted access to ssid.RESLEVEL resources. Example: $KEY(ssid) TYPE(MQA) RESLEVEL UID(*) PREVENT

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
