SV-76847r1_rule ColdFusion must set a maximum session time-out value.

Vulnerability discussion

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.

Check content

Within the Administrator Console, navigate to the "Memory Variables" page under the "Server Settings" menu. If the "Session Variables" setting under the "Maximum Timeout" section is set greater than "1" hour, this is a finding.

Fix text

Navigate to the "Memory Variables" page under the "Server Settings" menu. Set the "Session Variables" setting under the "Maximum Timeout" section to "1" hour or less and select the "Submit Changes" button.

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.
