Executive Summary

This vulnerability is a command injection flaw in the MSI Radix AXE6600 router firmware version v781521. It exists in the accesscontrol function and allows remote attackers to execute arbitrary commands with root privileges on the device. The issue arises from improper handling of special elements in OS commands, enabling unauthenticated remote code execution.

Detection Guidance

Detecting this vulnerability requires checking the firmware version of the MSI Radix AXE6600 router. If the firmware version is v781521 or earlier, the device is vulnerable. Use the router's admin interface or SSH to check the firmware version. No specific commands are provided in the resources.

Impact Analysis

This vulnerability allows attackers to take full control of your router remotely. They can execute malicious commands, install malware, intercept network traffic, or use the device as part of a botnet. Since the router is often a gateway to your network, this could compromise all connected devices and sensitive data.

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 may violate compliance requirements under GDPR and HIPAA. Organizations using this firmware version must address the flaw to maintain regulatory compliance.

Mitigation Strategies

Immediately update the router's firmware to version v782418 or later, as this version includes the patch for the vulnerability. If updating is not possible, consider isolating the device from untrusted networks or disabling remote access features until the update can be applied.
