CVE-2022-40486Public exploitNetwork attack vector

Authenticated code execution via backup XML handler injection

Published Sep 28, 2022 · Updated May 21, 2025

Code injection in TP-Link Archer AX10 V1 firmware 1.3.1 Build 20220401 allows remote authenticated users to execute arbitrary code. The restore path imports modified backup XML whose renamed button node bypasses protection for a handler parameter and installs an attacker-chosen command. Administrative web-interface access and a configuration restore are required; triggering the injected handler opens a shell on the router.
