Description

An issue was discovered in Asterisk Open Source 13.x before 13.21.1, 14.x before 14.7.7, and 15.x before 15.4.1 and Certified Asterisk 13.18-cert before 13.18-cert4 and 13.21-cert before 13.21-cert2. 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.

Affected configurations

• digium asterisk (>= 13.0.0 < 13.21.1) • digium asterisk (> 14.0.0 < 14.7.7) • digium asterisk (>= 15.0.0 < 15.4.1) • digium certified asterisk 13.18 • digium certified asterisk 13.21 • debian debian linux 9.0
