Vulnerability discussion

If an MQ Appliance device management session or connection remains open after management is completed, it may be hijacked by an attacker and used to compromise or damage the MQ Appliance network device. Nonlocal MQ Appliance device management and diagnostic activities are those activities conducted by individuals communicating through a network, either an external network (e.g., the Internet) or an internal network. In the event the remote node has abnormally terminated or an upstream link from the managed device is down, the management session will be terminated, thereby freeing device resources and eliminating any possibility of an unauthorized user being orphaned to an open idle session of the managed device.

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.
