{"id":"ALPINE-CVE-2019-18790","details":"An issue was discovered in channels/chan_sip.c in Sangoma Asterisk 13.x before 13.29.2, 16.x before 16.6.2, and 17.x before 17.0.1, and Certified Asterisk 13.21 before cert5. A SIP request can be sent to Asterisk that can change a SIP peer's IP address. A REGISTER does not need to occur, and calls can be hijacked as a result. The only thing that needs to be known is the peer's name; authentication details such as passwords do not need to be known. This vulnerability is only exploitable when the nat option is set to the default, or auto_force_rport.","modified":"2026-09-10T06:17:54.522393574Z","published":"2019-11-22T17:15:11.740Z","upstream":["CVE-2019-18790"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2019-18790"}],"affected":[{"package":{"name":"asterisk","ecosystem":"Alpine:v3.10","purl":"pkg:apk/alpine/asterisk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"13.0.0"},{"fixed":"16.3.0-r3"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-18790.json"}},{"package":{"name":"asterisk","ecosystem":"Alpine:v3.11","purl":"pkg:apk/alpine/asterisk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"13.0.0"},{"fixed":"16.6.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-18790.json"}},{"package":{"name":"asterisk","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/asterisk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"13.0.0"},{"fixed":"16.6.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-18790.json"}},{"package":{"name":"asterisk","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/asterisk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"13.0.0"},{"fixed":"16.6.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-18790.json"}},{"package":{"name":"asterisk","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/asterisk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"13.0.0"},{"fixed":"16.6.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-18790.json"}},{"package":{"name":"asterisk","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/asterisk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"13.0.0"},{"fixed":"16.6.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-18790.json"}},{"package":{"name":"asterisk","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/asterisk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"13.0.0"},{"fixed":"16.6.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-18790.json"}},{"package":{"name":"asterisk","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/asterisk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"13.0.0"},{"fixed":"16.6.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-18790.json"}},{"package":{"name":"asterisk","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/asterisk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"13.0.0"},{"fixed":"16.6.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-18790.json"}},{"package":{"name":"asterisk","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/asterisk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"13.0.0"},{"fixed":"16.6.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-18790.json"}},{"package":{"name":"asterisk","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/asterisk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"13.0.0"},{"fixed":"16.6.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-18790.json"}},{"package":{"name":"asterisk","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/asterisk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"13.0.0"},{"fixed":"16.6.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-18790.json"}},{"package":{"name":"asterisk","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/asterisk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"13.0.0"},{"fixed":"16.6.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-18790.json"}},{"package":{"name":"asterisk","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/asterisk?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"13.0.0"},{"fixed":"16.6.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-18790.json"}},{"package":{"name":"asterisk","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/aste
