GSD-2019-25025

Vulnerability from gsd - Updated: 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.

GHSA-CVW2-XJ8R-MJF7

Vulnerability from github – Published: 2021-03-09 00:45 – Updated: 2023-09-05 22:00

Summary

Activerecord-session_store Vulnerable to Timing Attack

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

This has been fixed in version 2.0.0. All users are advised to update to this version or later.

Severity

5.3 (Medium)
