CVE-2026-2151Public exploitNetwork attack vector

Authenticated command execution via unsanitized DMZ address

Published Feb 8, 2026 · Updated Feb 8, 2026

OS command injection in the D-Link DIR-615 4.10 DMZ Host Feature allows remote authenticated users to execute commands through dmz_ipaddr. The adv_firewall.php handler passes the attacker-controlled DMZ address into an operating-system command without neutralizing command elements. Administrative privileges are required, and injected commands execute in the router's operating-system context.
