Descriptions

The activerecord-session_store (aka Active Record Session Store) component through 1.1.3 for Ruby on Rails does not use a constant-time approach when delivering information about whether a guessed session ID is valid. Consequently, remote attackers can leverage timing discrepancies to achieve a correct guess in a relatively short amount of time. This is a related issue to CVE-2019-16782.

El componente activerecord-session_store (también se conoce como Active Record Session Store) hasta 1.1.3 para Ruby en Rails, no usa un enfoque de tiempo constante al entregar información sobre si una ID de sesión adivinada es válida. En consecuencia, los atacantes remotos pueden aprovechar las discrepancias de tiempo para lograr una conjetura correcta en un período de tiempo relativamente corto. Este es un problema relacionado al CVE-2019-16782
