            // redirect after import

Other recommendations

  • It’s recommended to upgrade to the latest version of the module creativepopup.
  • Upgrade PrestaShop to the latest version to disable multiquery executions (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_ with 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 this set of rules.
