FreeBSD : asterisk -- PJSIP endpoint presence disclosure when using ACL (0137167b-6dca-11e8-a671-001999f8d30b)

high Nessus Plugin ID 110465

Language:

Synopsis

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

Description

The Asterisk project reports :

When endpoint specific ACL rules block a SIP request they respond with a 403 forbidden. However, if an endpoint is not identified then a 401 unauthorized response is sent. This vulnerability just discloses which requests hit a defined endpoint. The ACL rules cannot be bypassed to gain access to the disclosed endpoints.

Solution

Update the affected packages.
