CVE-2025-6899Public exploitNetwork attack vector

Authenticated command execution via unsanitized request parameters

Published Jun 30, 2025 · Updated Jun 30, 2025

OS command injection in D-Link DI-7300G+ and DI-8200G 17.12.20A1 and 19.12.25A1 allows remote authenticated users to execute commands. The msp_info.htm handler passes attacker-controlled flag, cmd, and iface parameters to an operating-system command without neutralizing shell metacharacters. Low-privileged web-management access is required, and successful exploitation runs commands in the router firmware context.
