For PrestaShop 1.7, with sendingblue version 4.x, remove all files ajaxXXX.php especially ajaxOrderTracking.php.

Other recommandations

It’s highly recommended to upgrade the module to the latest version or to delete the module if unused.
Upgrade PrestaShop to the latest version to disable multiquery execution (separated by “;”) - be warned that this functionality WILL NOT protect your SHOP against injection SQL which uses the UNION clause to steal data.
Change the default database prefix ps_ by a new longer arbitrary prefix. Nevertheless, be warned that this is useless against blackhats with DBA senior skills because of a design vulnerability in DBMS
Activate OWASP 942’s rules on your WAF (Web application firewall), be warned that you will probably break your backoffice and you will need to pre-configure some bypasses against these set of rules.
