Researchers from the University of California, San Diego, have published a practical exploit for this flaw, marking the first successful demonstration of an attack against the RADIUS protocol. The FreeRADIUS Server Project has promptly responded with guidance and updates to mitigate this significant threat.
The FreeRADIUS Server Project has provided the following recommendations to secure systems:
require_message_authenticator = true in all client definitions.
limit_proxy_state = yes.require_message_authenticator attribute is present in all Access-Request packets and upgrade other RADIUS servers to prevent the attack.The discovery of CVE-2024-6387 underscores the importance of diligent cybersecurity practices and the necessity of safeguarding and continuously monitoring systems. Organizations must act promptly to patch vulnerable systems and strengthen their security posture to mitigate the risks associated with this severe vulnerability.
While the BlastRADIUS vulnerability (CVE-2024-3596) requires a man-in-the-middle position, implying a network may already be compromised if exploited, immediate action is crucial. FreeRADIUS users are advised to implement the recommended configuration changes and stay updated with the latest security guidance to protect their networks.
