Descriptions

The Tawk.To Live Chat WordPress plugin before 0.6.0 does not have capability and CSRF checks in the tawkto_setwidget and tawkto_removewidget AJAX actions, available to any authenticated user. The first one allows low-privileged users (including simple subscribers) to change the 'tawkto-embed-widget-page-id' and 'tawkto-embed-widget-widget-id' parameters. Any authenticated user can thus link the vulnerable website to their own Tawk.to instance. Consequently, they will be able to monitor the vulnerable website and interact with its visitors (receive contact messages, answer, ...). They will also be able to display an arbitrary Knowledge Base. The second one will remove the live chat widget from pages.

El plugin Tawk.To Live Chat de WordPress versiones anteriores a 0.6.0, no dispone de comprobaciones de capacidad y CSRF en las acciones AJAX tawkto_setwidget y tawkto_removewidget, disponibles para cualquier usuario autenticado. La primera permite a usuarios con pocos privilegios (incluidos los simples suscriptores) cambiar los parámetros "tawkto-embed-widget-page-id" y "tawkto-embed-widget-widget-id". Así, cualquier usuario autenticado puede vincular el sitio web vulnerable a su propia instancia de Tawk.to. En consecuencia, podrán supervisar el sitio web vulnerable e interactuar con sus visitantes (recibir mensajes de contacto, responder, ...). También podrán mostrar una Base de Conocimientos arbitraria. El segundo eliminará el widget de chat en vivo de las páginas
