CVE-2025-41427Network attack vector

Authenticated command injection via Connection Diagnostics request

Published Jun 24, 2025 · Updated Jun 25, 2025

OS command injection in ELECOM WRC-X3000GS-series firmware allows remote authenticated users to execute commands through crafted requests. The Connection Diagnostics page passes request data containing unneutralized OS-command elements into a system command. Access to the authenticated management interface is required, and successful exploitation runs arbitrary OS commands on the router.
