Title

User timeout parameter values for WebSphere MQ queue managers are not specified in accordance with security requirements. (Cat II impact)

Discussion

Users signed on to a WebSphere MQ queue manager could leave their terminals unattended for long periods of time. This may allow unauthorized individuals to gain access to WebSphere MQ resources and application data. This exposure could compromise the availability, integrity, and confidentiality of some system services and application data.
