Descripción

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