To exploit this, a user needs to be tricked to use an image from a specially crafted website and add it to HTML editor areas of OX App Suite, for example E-Mail Compose or OX Text. This specific attack circumvents typical XSS filters and detection mechanisms since the code is not loaded from an external service but injected locally.

A\u00f1adir im\u00e1genes de recursos externos a los editores HTML con drag&drop puede potencialmente permitir una ejecuci\u00f3n de c\u00f3digo script en el contexto de un usuario activo.

Este ataque espec\u00edfico evita los filtros XSS y los mecanismos de detecci\u00f3n t\u00edpicos, ya que el c\u00f3digo no se carga desde un servicio externo sino que se inyecta localmente. El c\u00f3digo script malicioso puede ser ejecutado en un contexto de usuario.
