Description
Rack::Session is a session management implementation for Rack. In versions starting from 2.0.0 to before 2.1.1, when using the Rack::Session::Pool middleware, and provided the attacker can acquire a session cookie (already a major issue), the session may be restored if the attacker 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. This issue has been patched in version 2.1.1.
Problem types
CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition
