CVE-2022-43627

Root code execution via static-route command injection

Published Mar 29, 2023 · Updated Feb 14, 2025

OS command injection in D-Link DIR-1935 1.03 firmware allows remote attackers on an adjacent network to execute arbitrary code as root. The SetStaticRouteIPv4Settings handler passes an unvalidated string from a StaticRouteIPv4Data subelement to a system call. The request requires management authentication, but the router's existing authentication mechanism can be bypassed, resulting in root-level appliance control.
