Command injection in TP-Link Archer and TL-MR series routers allows an adjacent unauthenticated attacker on the same broadcast domain to execute arbitrary commands with elevated privileges by supplying crafted DHCP option responses. The flaw resides in DHCP client option processing during device initialization and is most reliably triggered when the router is in factory-default or unconfigured state. No public exploit identified at time of analysis, but the vendor (TP-Link) has confirmed the issue and released firmware patches.
