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 OS/390 & z/OS Data Collection: - MQSRPT(ssid) NOTE: ssid is the queue manager name (a.k.a., subsystem identifier). Automated Analysis Refer to the following report produced by the OS/390 & z/OS Data Collection: - PDI(ZWMQ0051) b) Review the Security switches identified in response to the DISPLAY SECURITY command in each ssid report(s). If the all of the following switches specify ON, there is NO FINDING. SUBSYSTEM CONNECTION COMMAND CONTEXT ALTERNATE USER PROCESS NAMELIST QUEUE COMMAND RESOURCES c) If SUBSYSTEM specifies OFF, this is a FINDING with a severity of Category I. d) If any of the other above switches specify OFF (other than the exception mentioned below), this is a FINDING downgrade the severity to a Category II. e) If COMMAND RESOURCE Security switch specify OFF, there is NO FINDING. NOTE: At the discretion of the IAO, COMMAND RESOURCE Security switch may specify OFF, by defining ssid.NO.CMD.RESC.CHECKS in the TYPE(MQA).

The IAO will ensure that all Switch Profiles do not have the resource ssid.NO defined to the MQADMIN resource class with the exception of ssid.NO.CMD.RESC.CHECKS. ssid is the queue manager name (a.k.a., subsystem identifier). Ensure that all of the following switches specify ON. SUBSYSTEM CONNECTION COMMAND CONTEXT ALTERNATE USER PROCESS NAMELIST QUEUE COMMAND RESOURCES Example: $KEY(ssid) TYPE(MQA) ALTERNATE.USER.- UID(*) PREVENT CONTEXT.- UID(*) PREVENT RESLEVEL UID(*) PREVENT - UID(*) PREVENT NOTE: At the discretion of the IAO, COMMAND RESOURCE Security switch may specify OFF, by defining ssid.NO.CMD.RESC.CHECKS in the TYPE(MQA). Example: $KEY(ssid) TYPE(MQA) NO.CMD.RESC.CHECKS 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.
