Summary

Netcore NR268 from 1.7.121109 contains a cross-site scripting flaw (CWE-79) in its DHCP Handler component. The eval function of dhcp_dynamicip_show.cgi does not neutralize the Hostname argument, so injected script runs in the page. A remote attacker needs no privileges, but a user must interact with the page. A public exploit is linked in the references.
