CVE-2024-9140Network attack vector

Unauthenticated code execution via command-filter bypass

Published Jan 3, 2025 · Updated Jan 3, 2025

OS command injection in Moxa router and security-appliance firmware allows remote attackers to execute arbitrary code through crafted input. Special characters bypass command-input restrictions and reach improperly restricted OS commands in the affected device firmware. Network access without authentication is sufficient, and successful exploitation grants arbitrary command execution with system-wide impact.
