FreeBSD : openvox -- Flawed Hostname Check allows Puppet Client Impersonation (6cd47e21-d8db-11f1-8d43-18cf5efc6bb4)

critical Nessus Plugin ID 376438

Synopsis

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

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 6cd47e21-d8db-11f1-8d43-18cf5efc6bb4 advisory.

The OpenVoxProject reports:
Trapperkeeper is the framework we use for running our Clojure based applications and trapperkeeper-authorization is the shared authentication library that parses OpenVoxs auth.conf file and such. This file allows authentication rules to be specified in multiple ways, including plain strings (foo.example.com), wildcards (*.example.com), or regular expressions (/lab-\d{3}.example.com/).
Plain strings and wildcard matches were handled by the same logic and this resulted in wildcard behavior incorrectly showing up in all non-regex rules. The end result of this meant that a certificate name of evil.target.example.com would be allowed to impersonate target.example.com and access information or perform actions as the target certname. In some non-default configurations, this could even inject exported resources into arbitrary agent catalogs across the infrastructure.

Tenable has extracted the preceding description block directly from the FreeBSD 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.
