Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS : FreeRADIUS vulnerability (USN-7055-1)

critical Nessus Plugin ID 208094

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-7055-1 advisory.

 Goldberg, Miro Haller, Nadia Heninger, Mike Milano, Dan Shumow, Marc Stevens, and Adam Suhl discovered that FreeRADIUS incorrectly authenticated certain responses. An attacker able to intercept communications between a RADIUS client and server could possibly use this issue to forge responses, bypass authentication, and access network devices and services.

 This update introduces new configuration options called limit_proxy_state and require_message_authenticator that default to auto but should be set to yes once all RADIUS devices have been upgraded on a network.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Solution

Update the affected packages.
