CVE-2017-9148 FreeRADIUS vulnerability
Title: FreeRADIUS vulnerability
Summary: FreeRADIUS would allow unintended access over the network.
Stefan Winter and Luboš Pavlíček discovered that FreeRADIUS incorrectly
handled the TLS session cache. A remote attacker could possibly use this
issue to bypass authentication by resuming an unauthenticated session.
Instructions: In general, a standard system update will make all the necessary changes.

CVE-2017-9148 [CRITICAL] CWE-287 freeradius: TLS resumption authentication bypass
freeradius: TLS resumption authentication bypass
The TLS session cache in FreeRADIUS 2.1.1 through 2.1.7, 3.0.x before 3.0.14, 3.1.x before 2017-02-04, and 4.0.x before 2017-02-04 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.
An authentication bypass flaw was found in the way the EAP module in FreeRADIUS handled TLS session resumption. A remote unauthenticated attacker could potentially use this flaw to bypass the inner authentication check in FreeRADIUS by resuming an older unauthenticated TLS session.
Mitigation: Disable TLS session caching in FreeRADIUS by setting "enable = no" in the cache subsection of EAP module settings, which are in /etc/raddb/mod
