In NETGEAR Nighthawk X10-R900 prior to 1.0.4.24 by sending a DHCP discover request containing a malicious hostname field an attacker may execute stored XSS attacks against this device. When the malicious DHCP request is received the device will generate a log entry containing the malicious hostname. This log entry may then be viewed at Advanced settings->Administration->Logs to trigger the exploit. Although this value is inserted into a textarea tag converted to all-caps and limited in length attacks are still possible.
