Descriptions

Meshtastic firmware is a device firmware for the Meshtastic project. The Meshtastic firmware does not check for packets claiming to be from the special broadcast address (0xFFFFFFFF) which could result in unexpected behavior and potential for DDoS attacks on the network. A malicious actor could craft a packet to be from that address which would result in an amplification of this one message into every node on the network sending multiple messages. Such an attack could result in degraded network performance for all users as the available bandwidth is consumed. This issue has been addressed in release version 2.5.6. All users are advised to upgrade. There are no known workarounds for this vulnerability.

El firmware Meshtastic es un firmware de dispositivo para el proyecto Meshtastic. El firmware Meshtastic no comprueba los paquetes que dicen provenir de la dirección de difusión especial (0xFFFFFFFF), lo que podría generar un comportamiento inesperado y la posibilidad de ataques DDoS en la red. Un actor malintencionado podría crear un paquete que diga que proviene de esa dirección, lo que daría como resultado una amplificación de este mensaje en cada nodo de la red que envíe múltiples mensajes. Un ataque de este tipo podría provocar una degradación del rendimiento de la red para todos los usuarios, ya que se consume el ancho de banda disponible. Este problema se ha solucionado en la versión 2.5.6. Se recomienda a todos los usuarios que actualicen. No existen workarounds conocidas para esta vulnerabilidad.
