CVE-2024-3596: RADIUS Protocol CVE-2024-3596
First published: Wed Feb 07 2024(Updated: )
A fundamental design flaw within the RADIUS protocol has been proven to be exploitable, compromising the integrity in the RADIUS Access-Request process. The attack allows a malicious user to modify packets in a way that would be indistinguishable to a RADIUS client or server. To be successful, the attacker must have the ability to inject themselves between the client and server.
