Possible malicious usage

  • Technical and personal data leaks
  • Obtain admin access
  • Remove all data of the linked PrestaShop
  • Display sensitives tables to front-office to unlock potential admin’s ajax scripts of modules protected by token on the ecosystem

Other recommendations

  • It’s recommended to delete the module
  • 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_ by a new longer arbitrary prefix. Nevertheless, be warned that this is useless against blackhats with DBA senior skill 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.
