Descriptions

The File Manager Pro WordPress plugin before 1.8 does not properly check the CSRF nonce in the `fs_connector` AJAX action. This allows attackers to make highly privileged users perform unwanted file system actions via CSRF attacks by using GET requests, such as uploading a web shell.

El complemento File Manager Pro de WordPress anterior a la versión 1.8 no verifica correctamente el nonce de CSRF en la acción AJAX `fs_connector`. Esto permite a los atacantes hacer que usuarios con privilegios elevados realicen acciones no deseadas en el sistema de archivos mediante ataques CSRF mediante solicitudes GET, como cargar una shell web.

The File Manager Pro plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.7.6. This is due to missing or incorrect nonce validation on the fsConnector function. This makes it possible for unauthenticated attackers to rename an arbitrary file and ultimately execute arbitrary code via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
