Descriptions

The Better Search plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.5.2. This is due to missing or incorrect nonce validation on the bsearch_process_settings_import() and bsearch_process_settings_export() functions. This makes it possible for unauthenticated attackers to import and export settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

El plugin Better Search para WordPress es vulnerable a ataques de tipo Cross-Site Request Forgery (CSRF) en versiones hasta la 2.5.2 inclusive. Esto se debe a la falta o incorrecta validación nonce en las funciones "bsearch_process_settings_import()" y "bsearch_process_settings_export()". Esto hace posible que atacantes no autenticados importen y exporten configuraciones a través de una solicitud manipulada concedida y puedan engañar a un administrador del sitio para que realice una acción como hacer clic en un enlace.
