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.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
