CVE-2020-9377Known exploitationNetwork attack vector

Authenticated command execution via cmd parameter

Published Jul 9, 2020 · Updated Oct 21, 2025

Command injection in D-Link DIR-610 command.php allows remote authenticated users to execute operating-system commands via cmd. The endpoint executes attacker-supplied cmd input; accessible records do not disclose the underlying implementation, and the referenced exploit is unavailable. Exploitation requires management-interface access and authentication; the vendor identifies hardware revision Ax without specifying affected firmware versions.
