Cross-site request forgery (CSRF) vulnerability in NETGEAR DGN2200 routers with firmware 10.0.0.20 through 10.0.0.50 allows remote attackers to hijack the authentication of users for requests that perform DNS lookups via the host_name parameter to dnslookup.cgi. NOTE: this issue can be combined with CVE-2017-6334 to execute arbitrary code remotely.
