Descriptions

The Content Blocks (Custom Post Widget) plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 3.3.0 via the plugin's 'content_block' shortcode. This makes it possible for authenticated attackers, with contributor-level access and above, to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included.

El complemento Content Blocks (Widget de publicación personalizado) para WordPress es vulnerable a la inclusión de archivos locales en todas las versiones hasta la 3.3.0 incluida a través del código corto 'content_block' del complemento. Esto hace posible que atacantes autenticados, con acceso de nivel de colaborador y superior, incluyan y ejecuten archivos arbitrarios en el servidor, permitiendo la ejecución de cualquier código PHP en esos archivos. Esto se puede utilizar para eludir los controles de acceso, obtener datos confidenciales o lograr la ejecución de código en los casos en que se puedan cargar e incluir imágenes y otros tipos de archivos "seguros".
