Descriptions

The User Post Gallery WordPress plugin through 2.19 does not limit what callback functions can be called by users, making it possible to any visitors to run code on sites running it.

El complemento User Post Gallery de WordPress hasta la versión 2.19 no limita las funciones de devolución de llamada que pueden invocar los usuarios, lo que permite a cualquier visitante ejecutar código en los sitios que lo ejecutan.

The User Post Gallery - UPG plugin for WordPress is vulnerable to authorization bypass which leads to remote command execution due to the use of a nopriv AJAX action and user supplied function calls and parameters in versions up to, and including 2.19. This makes it possible for unauthenticated attackers to call arbitrary PHP functions and perform actions like adding new files that can be webshells and updating the site's options to allow anyone to register as an administrator.
