Overview

On February 3, 2024, through our coordination with CERT/CC VINCE we became aware of the RADIUS Protocol under RFC2865 is vulnerable to forgery attacks.

D-Link Corporation recognizes the security issue and is in process of developing patches for the issue.

D-Link was aware of the  report early, the solution to mitigate this issue has taken time under the professional guidence of FreeRADIUS.  Patches were made available, however during development we found that mitigation would disable other features in the device, so we require time to develop and FULLY test for patches for our customers.

We will continue to update this announcement as more information is made available.

D-Link takes network security and user privacy very seriously. We have a dedicated task force and product management team on call to address evolving security issues and implement appropriate security measures.

Report Information  

         - Report by: https://www.blastradius.fail/

 
                     - Summary

                         The Blast-RADIUS attack allows a man-in-the-middle attacker between the RADIUS client and server to forge a valid protocol accept message in response to a failed authentication request. This forgery could give the attacker access to network devices and services without the attacker guessing or brute forcing passwords or shared secrets. The attacker does not learn user credentials.
