| Descripción | Several DHCP/DNS routes serialize attacker-controlled strings with %s into pseudo-JSON, and the web UI parses the response with eval('('+data+')'). The strongest case is dhcp_dynamicip_show.cgi: DHCP client hostnames are stored without quote escaping and later executed in the administrator browser. The same unescaped reflection pattern is reused for static DHCP names, dnsmasq hosts, IP-DNS rule names, and DDNS fields, so an unauthenticated LAN client can persist JavaScript by choosing a malicious DHCP hostname. |
