CVE-2022-43642

Admin code execution via unvalidated system-call input

Published Mar 29, 2023 · Updated Feb 14, 2025

OS command injection in D-Link DIR-825 firmware 1.0.9 and earlier allows attackers to execute arbitrary code via adjacent-network requests. The xupnpd YouTube plugin on TCP port 4044 passes a user-supplied string to a system call without proper validation. Authentication is not required, and injected commands run with admin privileges on the router.
