PrestaShop is an open source e-commerce web application that, prior to version 8.0.1, is vulnerable to cross-site request forgery (CSRF). When authenticating users, PrestaShop preserves session attributes. Because this does not clear CSRF tokens upon login, this might enable same-site attackers to bypass the CSRF protection mechanism by performing an attack similar to a session-fixation. The problem is fixed in version 8.0.1.
PrestaShop is an open-source e-commerce solution. Versions prior to 1.7.8.8 did not properly restrict host filesystem access for users. Users may have been able to view the contents of the upload directory without appropriate permissions. This issue has been addressed and users are advised to upgrade to version 1.7.8.8. There are no known workarounds for this issue.
In PrestaShop before version 1.7.6.9 an attacker is able to list all the orders placed on the website without being logged by abusing the function that allows a shopping cart to be recreated from an order already placed. The problem is fixed in 1.7.6.9.
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.
In PrestaShop before 1.7.6.0 RC2, the id_address_delivery and id_address_invoice parameters are affected by an Insecure Direct Object Reference vulnerability due to a guessable value sent to the web application during checkout. An attacker could leak personal customer information. This is PrestaShop bug #14444.
In the orders section of PrestaShop before 1.7.2.5, an attack is possible after gaining access to a target store with a user role with the rights of at least a Salesman or higher privileges. The attacker can then inject arbitrary PHP objects into the process and abuse an object chain in order to gain Remote Code Execution. This occurs because protection against serialized objects looks for a 0: followed by an integer, but does not consider 0:+ followed by an integer.
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).
