Descriptions

Within the Umbraco CMS, a configuration element named "UmbracoApplicationUrl" (or just "ApplicationUrl") is used whenever application code needs to build a URL pointing back to the site. For example, when a user resets their password and the application builds a password reset URL or when the administrator invites users to the site. For Umbraco versions less than 9.2.0, if the Application URL is not specifically configured, the attacker can manipulate this value and store it persistently affecting all users for components where the "UmbracoApplicationUrl" is used. For example, the attacker is able to change the URL users receive when resetting their password so that it points to the attackers server, when the user follows this link the reset token can be intercepted by the attacker resulting in account takeover.

Dentro del CMS Umbraco, un elemento de configuración llamado "UmbracoApplicationUrl" (o simplemente "ApplicationUrl") es usado siempre que el código de la aplicación necesita construir una URL que apunte al sitio. Por ejemplo, cuando un usuario restablece su contraseña y la aplicación construye una URL de restablecimiento de contraseña o cuando el administrador invita a usuarios al sitio. Para las versiones de Umbraco inferiores a 9.2.0, si la URL de la aplicación no está configurada específicamente, el atacante puede manipular este valor y almacenarlo de forma persistente afectando a todos los usuarios de los componentes en los que es usado "UmbracoApplicationUrl". Por ejemplo, el atacante es capaz de cambiar la URL que reciben los usuarios al restablecer su contraseña para que apunte al servidor del atacante, cuando el usuario sigue este enlace el token de restablecimiento puede ser interceptado por el atacante resultando en la toma de la cuenta
