SQL injection vulnerability in the City Autocomplete (cityautocomplete) module from ebewe.net for PrestaShop, prior to version 1.8.12 (for PrestaShop version 1.5/1.6) or prior to 2.0.3 (for PrestaShop version 1.7), allows remote attackers to execute arbitrary SQL commands via the type, inputname. or q parameter in the autocompletion.php front controller.

modules/orderfiles/ajax/upload.php in the Customer Files Upload addon 2018-08-01 for PrestaShop (1.5 through 1.7) allows remote attackers to execute arbitrary code by uploading a php file via modules/orderfiles/upload.php with auptype equal to product (for upload destinations under modules/productfiles), order (for upload destinations under modules/files), or cart (for upload destinations under modules/cartfiles).

In PrestaShop from version 1.5.0.0 and before version 1.7.6.8, users are allowed to send compromised files. These attachments allowed people to input malicious JavaScript which triggered an XSS payload. The problem is fixed in version 1.7.6.8.

In PrestaShop from version 1.5.0.0 and before version 1.7.6.6, the authentication system is malformed and an attacker is able to forge requests and execute admin commands. The problem is fixed in 1.7.6.6.
