Asus DSL-N14U-B1 1.1.2.3805 allows remote attackers to cause a Denial of Service (DoS) via a TCP SYN scan using nmap.

An issue was discovered on ASUS DSL-N14U-B1 1.1.2.3805 devices. An attacker can upload arbitrary file content as a firmware update when the filename SettingsDSL-N14U-B1.trx is used. Once this file is loaded, shutdown measures on a wide range of services are triggered as if it were a real update, resulting in a persistent outage of those services.
