BIG-IP, 3-DNS, and OpenBSD login_radius security bypass
| bigip-3dns-openbsd-security-bypass (20237) |  High Risk |
Description:
Big-IP, 3-DNS Controller, and OpenBSD could allow a remote attacker to bypass security caused by a vulnerability in the login_radius. The login_radius fails to properly check the shared secret regarding replies received from the radius server. If the radius authentication is enabled, a remote attacker could send a specially-crafted spoofed response with origin being the radius server to bypass security restrictions.
Consequences:
