What to do
Workaround: The DoSFilter can be configured to not use sessions for tracking usage by setting the trackSessions init parameter to false. This will then use only the IP tracking mechanism, which is not vulnerable. Sessions can also be configured to have aggressive passivation or inactivation limits.
