RADIUS Vulnerability – Schneier on Security
RADIUS Vulnerability
New attack against the RADIUS authentication protocol:
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.
This is one of those vulnerabilities that comes with a cool name, its own website, and a logo.
