Drupalgeddon2 exploit is possible on Drupal 7.59 after updating

Hello Evebody,

For security purpose and to follow Drupal recommendation we make an update from Drupal version 7.56 to version 7.59.

Security advisories : https://www.drupal.org/SA-CORE-2018-004 ( If you are running 7.x, upgrade to Drupal 7.59 )

Problem is that after update performing we make a vulnerability test with Drupalgeddon2 ruby file and it woks well like on Drupal 7.56 version.

So I want to know if Drupal 7.59 doesn't resolve this issue (Remote Code Execution - SA-CORE-2018-004).

What can I do in my case to solve it ?

It necessary to perform an upgrade to Drupal 8.5 version to solve this issue ?

Thank you for your assistance.
