Vulnerability from variot
login_radius on OpenBSD 3.2, 3.5, and possibly other versions does not verify the shared secret in a response packet from a RADIUS server, which allows remote attackers to bypass authentication by spoofing server replies. OpenBSD is reported prone to an authentication bypass vulnerability when using Radius authentication. This issue can be leveraged by spoofing traffic on a vulnerable network and carrying out a man-in-the-middle attack to gain unauthorized access to an OpenBSD computer. This vulnerability arises if an OpenBSD computer is configured to use Radius authentication and may allow an attacker to gain unauthorized access to the OpenBSD computer. The vulnerability is confirmed in OpenBSD 3.2 and OpenBSD 3.5. Other versions may be vulnerable as well
