Possible malicious usage
- Technical and personal data leaks
- Obtain admin access
- Remove all data of the linked PrestaShop
- Display sensitive tables to front-office to unlock potential admin’s ajax scripts of modules protected by token on the ecosystem
--- a/modules/simpleimportproduct/send.php +++ b/modules/simpleimportproduct/send.php $key = Tools::getValue('key'); $key = pSQL($key); - Db::getInstance()->delete('simpleimport_tasks', "import_settings=$key"); + Db::getInstance()->delete('simpleimport_tasks', "import_settings='".$key."'");
- 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.
