CVSS 3.0
5.3 mediumCVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:NCVE-2018-12227
Medium (5.3). EPSS 3.4% chance of exploitation in the next 30 days.
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.
