This relates to handle_request in router/httpd/httpd.c and auth_check in web_hook.o. An attacker-supplied value of '\\0' matches the device's default value of '\\0' in some situations. Note: All versions of Lyra Mini and earlier which are unsupported (End-of-Life, EOL) are also affected by this vulnerability, Consumers can mitigate this vulnerability by disabling the remote access features from WAN."},{"lang":"es","value":"La aplicación de administrador en los dispositivos ASUS GT-AC2900 versiones anteriores a 3.0.0.4.386.42643, permite una omisión de autenticación cuando es
