Descriptions

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.

En NETGEAR Nighthawk X10-R900 versiones anteriores a 1.0.4.24, mediante el envío de una petición de detección de DHCP que contiene un campo hostname malicioso, un atacante puede ejecutar ataques de tipo XSS almacenado contra este dispositivo. Cuando es recibida una petición DHCP maliciosa, el dispositivo generará una entrada de registro que contiene el hostname malicioso. Esta entrada de registro puede entonces ser visualizada en Advanced settings-)Administration-)Logs para activar la explotación. Aunque este valor es insertado en una textarea tag, converted to all-caps, y limited in length, los ataques aún son posibles.
