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.
