CVE-2024-21833

Adjacent unauthenticated command execution

Published Jan 10, 2024 · Updated Jun 16, 2025

OS command injection in TP-Link Archer and Deco router firmware allows remote attackers on the LAN or Wi-Fi to execute arbitrary OS commands. The public advisory does not identify the vulnerable request handler, input field, or shell invocation that fails to neutralize untrusted input. Access from the LAN port or Wi-Fi is required, and successful exploitation grants command execution with the device process's privileges.
