Descriptions

The Welcart e-Commerce WordPress plugin before 2.9.5 does not validate files to be uploaded, as well as does not have authorisation and CSRF in an AJAX action handling such upload. As a result, any authenticated users, such as subscriber could upload arbitrary files, such as PHP on the server

El complemento Welcart e-Commerce de WordPress anterior a 2.9.5 no valida los archivos que se van a cargar, además de que no tiene autorización ni CSRF en una acción AJAX que maneje dicha carga. Como resultado, cualquier usuario autenticado, como un suscriptor, podría cargar archivos arbitrarios, como PHP, en el servidor.

The Welcart e-Commerce plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the upload_certificate_file function in all versions up to, and including, 2.9.4. This makes it possible for subscribers or higher to upload arbitrary files on the affected site's server which may make remote code execution possible.
