CVE-2025-10440Network attack vector

Authenticated command execution via injected hname argument

Published Sep 15, 2025 · Updated Sep 15, 2025

OS command injection in D-Link DI-series firmware 16.07.26A1, 17.12.20A1, and 19.12.10A1 allows remote authenticated users to run commands. The jhttpd sub_4621DC handler in usb_paswd.asp uses the attacker-controlled hname argument in an operating-system command without neutralizing command syntax. A low-privileged web-management session is required; exploitation executes commands with jhttpd's privileges and enables gateway data changes or service interruption.
