gsd-2019-25025
Vulnerability from gsd
Modified
2021-03-08 00:00
Details
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.
## Recommendation
Users should upgrade to `activerecord-session_store` version 2.0.0 or later.
