{"id":"CVE-2018-12227","details":"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.","modified":"2026-02-21T00:50:12.728321Z","published":"2018-06-12T04:29:00.220Z","references":[{"type":"ADVISORY","url":"http://downloads.asterisk.org/pub/security/AST-2018-008.html"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/104455"},{"type":"ADVISORY","url":"https://issues.asterisk.org/jira/browse/ASTERISK-27818"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/201811-11"},{"type":"ADVISORY","url":"https://www.debian.org/security/2018/dsa-4320"},{"type":"FIX","url":"https://issues.asterisk.org/jira/browse/ASTERISK-27818"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/asterisk/asterisk","events":[{"introduced":"0"},{"fixed":"fdaecead781e4216a68c672ad0864ca895a47141"},{"introduced":"85335355efb2d7914a1fe20ed31afcef15fd210c"},{"fixed":"d661052e6d2eddae58bec5a04229c105d11e18f4"},{"introduced":"d4cc63728def7ca06ad3f70547de87bc5c9ef7c0"},{"fixed":"97b17a97812a5b3f30dba94cc7b3b3a2e81473e5"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2018-12227.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}
