OS command injection in the TP-Link Archer C20 v6 web management interface enables an authenticated administrator to execute arbitrary system commands by submitting crafted WAN configuration inputs that bypass insufficient input validation. Full device compromise - confidentiality, integrity, and availability - is achievable for all traffic routed through the affected device. TP-Link has released a patched firmware; no public exploit code or CISA KEV listing has been identified at time of analysis.
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.
Hardcoded credentials in TP-Link router firmware allow attackers with physical access to gain unauthorized access to privileged functions, potentially leading to full device compromise. Affected models include TL-WR845N v4, TL-WR850N v3, Archer C20 v6, and Archer MR200 v5. No evidence of active exploitation or public exploit code exists at this time, and the physical access requirement limits remote exploitation risk.
