CVE-2022-43624

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 routers allows remote attackers on the adjacent network to execute arbitrary code through the management portal. The SetStaticRouteIPv6Settings handler passes an unvalidated string from a StaticRouteIPv6List subelement into a system call. Access nominally requires authentication, but the authentication mechanism is bypassable, yielding root-context execution.
