An authenticated OS command injection vulnerability exists in Netgear routers (tested on the DGN2200B model) firmware versions 1.0.0.36 and prior via the pppoe.cgi endpoint. A remote attacker with valid credentials can execute arbitrary commands via crafted input to the pppoe_username parameter. This flaw allows full compromise of the device and may persist across reboots unless configuration is restored.
