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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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. (CVE-2019-25025)

Note that Nessus relies on the presence of the package as reported by the vendor.
