Security Advisory

1) Authentication bypass

Description

The vulnerability allows a remote attacker to bypass authentication on the target system.

The weakness exists due to failure when preventing resumption of an unauthenticated session by TLS session cache. A remote attacker can use PEAP or TTLS to bypass authentication and cause the target server to issue an Extensible Authentication Protocol (EAP)

Successful exploitation of the vulnerability may result in unauthorized access to the system.

Remediation

Update to version 3.0.14.
