Applications used for nonlocal maintenance sessions using the MQ Appliance WebGUI must implement cryptographic mechanisms to protect the confidentiality and integrity of nonlocal maintenance and diagnostic communications.

From IBM MQ Appliance v9.0 NDM Security Technical Implementation Guide

SV-89681r1_rule Applications used for nonlocal maintenance sessions using the MQ Appliance WebGUI must implement cryptographic mechanisms to protect the confidentiality and integrity of nonlocal maintenance and diagnostic communications.

Vulnerability discussion

This requires the use of secure protocols instead of their unsecured counterparts, such as SSH instead of telnet, SCP instead of FTP, and HTTPS instead of HTTP. If unsecured protocols (lacking cryptographic mechanisms) are used for sessions, the contents of those sessions will be susceptible to manipulation, potentially allowing alteration and hijacking of maintenance sessions.Satisfies: SRG-APP-000411-NDM-000330, SRG-APP-000412-NDM-000331

Check content

Log on to the MQ Appliance CLI as a privileged user. Display the SSL Server Profile associated with the WebGUI (CLI). Enter: co show web-mgmt Verify the following: An ssl-server is associated with the WebGUI. [Note the name of the ssl-server.] List parameters of the SSL Server (CLI). Enter: co crypto ssl-server show Verify the following: protocols TLSv1d2 If TLS protocol is not configured for use with the ssl-server, this is a finding.

Fix text

Log on to the MQ Appliance CLI as a privileged user. Display the SSL Server Profile associated with the WebGUI (CLI). Enter: co show web-mgmt [Note the name of the ssl-server.] Define the cache parameters of the SSL Server (CLI). Enter: co crypto ssl-server protocols TLSv1d2 exit exit write mem y

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.
