[ASA-201706-2] freeradius: authentication bypass
Arch Linux Security Advisory ASA-201706-2 ========================================= Severity: High Date : 2017-06-02 CVE-ID : CVE-2017-9148 Package : freeradius Type : authentication bypass Remote : Yes Link : Summary ======= The package freeradius before version 3.0.14-3 is vulnerable to authentication bypass. Resolution ========== Upgrade to 3.0.14-3. # pacman -Syu "freeradius>=3.0.14-3" The problem has been fixed upstream in version 3.0.14. Workaround ========== None. Description =========== A security issue has been found in FreeRADIUS < 3.0.14. The implementation of TTLS and PEAP in FreeRADIUS skips inner authentication when it handles a resumed TLS connection. This is a feature but there is a critical catch: the server must never allow resumption of a TLS session until its initial connection gets to the point where inner authentication has been finished successfully. Unfortunately, affected versions of FreeRADIUS fail to reliably prevent resumption of unauthenticated sessions unless the TLS session cache is disabled completely and allow an attacker (e.g. a malicious supplicant) to elicit EAP Success without sending any valid credentials. Impact ====== A remote user can bypass authentication by starting then resuming an unauthenticated TLS session. References ==========
