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.
