Description
An attacker can take advantage of user sessions that are left open, thus bypassing the user authentication process. To thwart the vulnerability of open and unused user sessions, the application server must be configured to close the sessions when a configured condition or trigger event is met. Such an event is user inactivity. ColdFusion offers an inactivity parameter that allows the setting system-wide for session timeout. ColdFusion also allows a developer to override the default timeout setting and set a new timeout. To control how large a developer can set the timeout to, a maximum setting is provided.
