FreeRADIUS before 3.0.19 does not prevent use of reflection for authentication spoofing, aka a "Dragonblood" issue, a similar issue to CVE-2019-9497.

The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CESA-2019:1142 advisory.

  - freeradius: eap-pwd: fake authentication using reflection (CVE-2019-11234)

  - freeradius: eap-pwd: authentication bypass via an invalid curve attack (CVE-2019-11235)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

An update for freeradius is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

FreeRADIUS is a high-performance and highly configurable free Remote Authentication Dial In User Service (RADIUS) server, designed to allow centralized authentication and authorization for a network.

Security Fix(es) :

* freeradius: eap-pwd: authentication bypass via an invalid curve attack (CVE-2019-11235)
