CVE-2023-50214

Unauthenticated root code execution via unvalidated tar input

Published May 3, 2024 · Updated Aug 2, 2024

OS command injection in D-Link G416 firmware before 1.09B01 allows remote attackers on the LAN to execute arbitrary code as root. The HTTP service on TCP port 80 passes an unvalidated, user-supplied string from nodered tar file handling into a system call. No authentication is required, but the attacker must have LAN-side access to a non-US hardware revision Ax router.
