A command injection vulnerability has been identified in the DHCP option processing logic in multiple TP-Link router models, due to insufficient validation of externally supplied DHCP option data. An adjacent attacker may exploit this vulnerability by supplying crafted DHCP responses, potentially resulting in unauthorized command execution during device initialization or provisioning workflows. This typically occurs when the device is in a factory-default or unconfigured state. Successful exploitation may allow an adjacent, unauthenticated attacker to execute arbitrary commands with elevated privileges, potentially leading to full compromise of the affected device and unauthorized administrative control.
