Executive Summary

This vulnerability is a command injection flaw in the MSI Radix AXE6600 router firmware version v781521. It exists in the dmz function and allows remote attackers to execute arbitrary commands on the device with root privileges.

Detection Guidance

To detect this vulnerability, check if your MSI Radix AXE6600 router is running firmware version v781521 or earlier. Log in to the router's admin panel and navigate to the firmware version section. Alternatively, use network scanning tools to identify devices with open ports and check their firmware versions.

Impact Analysis

Attackers can exploit this to gain full control of your router, potentially intercepting network traffic, installing malware, or using the device as part of a botnet. Unauthorized root access could also lead to further compromise of connected systems.

Compliance Impact

This vulnerability allows remote attackers to execute arbitrary commands with root privileges on the affected MSI Radix AXE6600 router. Such unauthorized access could lead to data breaches, unauthorized data access, or system compromise, which are critical violations under GDPR and HIPAA. Organizations using this firmware may fail to meet compliance requirements for data protection and access controls.

Mitigation Strategies

Immediately update the router's firmware to version v782418 or later, which contains the fix for this vulnerability. If an update is not available, disable the DMZ function on the router as a temporary workaround to prevent exploitation.
