FreeBSD : FreeRADIUS -- TLS resumption authentication bypass (673dce46-46d0-11e7-a539-0050569f7e80)

critical Nessus Plugin ID 100581

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

Stefan Winter reports :

The TLS session cache in FreeRADIUS before 3.0.14 fails to reliably prevent resumption of an unauthenticated session, which allows remote attackers (such as malicious 802.1X supplicants) to bypass authentication via PEAP or TTLS.

Solution

Update the affected packages.
