CVE-2025-13800Public exploitNetwork attack vector

Authenticated command execution via unsanitized mac parameter

Published Dec 1, 2025 · Updated Dec 1, 2025

Command injection in NBR1005GPEV2 250814-r037c allows remote authenticated users to execute commands via a crafted mac argument. The set_mesh_disconnect function in /send_order.cgi places the mac argument into a command context without neutralizing command syntax. Reachability requires low-privilege access to the network management interface; successful injection executes commands on the router.
