A critical remote code execution vulnerability in Limatek System LimRAD NAC poses a severe risk to organizational infrastructure.

This vulnerability, categorized as CWE-434, involves the unrestricted upload of dangerous file types, which enables remote code inclusion. An attacker can leverage this flaw to execute arbitrary code on the underlying system.

With a CVSS score of 9.8, this vulnerability is classified as Critical. Successful exploitation could lead to a total compromise of the affected system, resulting in unauthorized access to internal network management functions, exfiltration of sensitive configuration data, and potential lateral movement within the environment.

Immediate Action: Upgrade LimRAD NAC to version 5.5.7.3.9 or higher immediately to address the file upload restriction flaw.

Proactive Monitoring: Review system logs for unauthorized file uploads or anomalous HTTP requests to the NAC management interface.

Compensating Controls: Implement Web Application Firewall (WAF) rules to inspect and block suspicious file extensions and MIME types uploaded to the web interface.

Public Exploit Available: false

The severity of this remote code execution vulnerability necessitates immediate attention. Administrators must prioritize updating the LimRAD NAC software to version 5.5.7.3.9 to eliminate the attack vector, as failure to do so leaves the network infrastructure exposed to complete takeover.
