      "value": "The web console for Mimosa B5, B5c, and C5x firmware through 2.8.0.2 is vulnerable to stored XSS in the set_banner() function of /var/www/core/controller/index.php. An unauthenticated attacker may set the contents of the /mnt/jffs2/banner.txt file, stored on the device's filesystem, to contain arbitrary JavaScript. The file contents are then used as part of a welcome/banner message presented to unauthenticated users who visit the login page for the web console. This vulnerability does not occur in the older 1.5.x firmware versions."

Un atacante no autenticado puede ajustar el contenido del archivo /mnt/jffs2/banner.txt, almacenado en el sistema de archivos del dispositivo, para que contenga JavaScript arbitrario. El contenido del archivo es usado entonces como parte de un mensaje de welcome/banner presentado a usuarios no autenticados que visitan la p\u00e1gina de inicio de sesi\u00f3n de la consola web. Esta vulnerabilidad no ocurre en las versiones de firmware 1.5.x m\u00e1s antiguas"
