CVE-2026-71993 is a critical OS command injection vulnerability affecting MSI Radix AXE6600 router firmware up to and including version v781521. The flaw is in the router's OpenVPN-related functionality, where insufficient neutralization of special elements in command input allows attacker-controlled data to be incorporated into operating system commands. Available reporting also indicates the issue can be triggered through the MAC filtering-related input path associated with the vulnerable OpenVPN handling. A remote, unauthenticated attacker can send crafted input to cause arbitrary command execution on the device, resulting in execution as root on the underlying system.
