In ASUS RT-AX3000, ZenWiFi AX (XT8), RT-AX88U, and other ASUS routers with firmware < 3.0.0.4.386.42095 or < 9.0.0.4.386.41994, when IPv6 is used, a routing loop can occur that generates excessive network traffic between an affected device and its upstream ISP's router. This occurs when a link prefix route points to a point-to-point link, a destination IPv6 address belongs to the prefix and is not a local IPv6 address, and a router advertisement is received with at least one global unique IPv6 prefix for which the on-link flag is set. En ASUS RT-AX3000, ZenWiFi AX (XT8), RT-AX88U y otros enrutadores ASUS con versiones de firmware anteriores a 3.0.0.4.386.42095 o versiones anteriores a 9.0.0.4.386.41994, cuando una IPv6 es usada, puede ocurrir un bucle de enrutamiento que genera un tráfico excesivo de red entre un dispositivo afectado y el enrutador de su ISP aguas arriba. Esto ocurre cuando una ruta de prefijo de enlace apunta a un enlace punto a punto, una dirección IPv6 de destino pertenece al prefijo y no es una dirección IPv6 local, y un anuncio de enrutador es recibido con al menos un prefijo IPv6 único global para el cual el flag on-link se establece • https://www.asus.com/Networking-IoT-Servers/Whole-Home-Mesh-WiFi-System/ZenWiFi-WiFi-Systems/ASUS-ZenWiFi-AX-XT8-/HelpDesk_BIOS https://www.asus.com/Networking-IoT-Servers/WiFi-6/All-series/RT-AX3000/HelpDesk_BIOS https://www.asus.com/Networking-IoT-Servers/WiFi-6/All-series/RT-AX55/HelpDesk_BIOS https://www.asus.com/Networking-IoT-Servers/WiFi-6/All-series/RT-AX56U/HelpDesk_BIOS https://www.asus.com/Networking-IoT-Servers/WiFi-6/All-series/RT-AX58U/HelpDesk_BIOS https://www. • CWE-834: Excessive Iteration •

An issue was discovered in the Merlin.PHP component 0.6.6 for Asuswrt-Merlin devices. An attacker can execute arbitrary commands because api.php has an eval call, as demonstrated by the /6/api.php?function=command&class=remote&Cc='ls' URI. NOTE: the vendor indicates that Merlin.PHP is designed only for use on a trusted intranet network, and intentionally allows remote code execution ** EN DISPUTA ** Se ha descubierto un problema en la versión 0.6.6 del componente Merlin.PHP para dispositivos Asuswrt-Merlin.
