Description
The vulnerability allows a remote user to escalate privileges on the system.
The vulnerability exists because when using the `Rack::Session::Pool` middleware, simultaneous rack requests can restore a deleted rack session. A remote user can trigger a long running request (within that same session) adjacent to the user logging out, in order to retain illicit access even after a user has attempted to logout.
Remediation
Install updates from vendor's website.
