Netcore NR255-V version 1.5.130703 contains a stored cross-site scripting vulnerability in the DHCP dynamic IP display and ARP bind list display components handling hostname fields. A LAN-based attacker can inject malicious script through these hostname fields, which is later rendered by network_config.js and network_security.js in the web management interface.
