Prior to Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3, an authenticated attacker may crash Asterisk through a buffer over-read in the `PJSIP MWI body parser` by sending a carefully crafted `SIP NOTIFY` request. The attacker must pass SIP authentication using either a username/password or `source IP address matching`. This issue is fixed in Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-126","CWE-170"],"vendors":[],"products":[],"references":[{"url":"https://github.com/asterisk/asterisk/commit/07aec894a1fdfa7fa989d3ab40fdf0dcda8005bb","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/1039bed76fa3248f58b6880e4b3f1421ef98b01f","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/1b2d99d8eb9206d37fd47115996f67fd28bd056f","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/3100a0d331affbf0995b8c57aaddb31cf3971f6e","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/57ce484a45b098de417f19265c95c64497782e36","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/919f2ffda03329c9014bedcb3c7789d38660c9ed","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/dafff9fb60281817225f1ce6371a5aa2fbb967a4","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/20.20.1","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/21.12.3","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/22.10.1","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/23.4.1","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/certified-20.7-cert11","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/certified-22.8-cert3","tags":[]},{"url":"https://github.com/asterisk/asterisk/security/advisories/GHSA-8jw3-ccr9-xrmf","tags":[]},{"url":"https://github.com/asterisk/asterisk/tree/24.0.0-pre1","tags":[]}],"exploitRefs":[{"url":"https://github.com/asterisk/asterisk/commit/07aec894a1fdfa7fa989d3ab40fdf0dcda8005bb","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/1039bed76fa3248f58b6880e4b3f1421ef98b01f","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/1b2d99d8eb9206d37fd47115996f67fd28bd056f","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/3100a0d331affbf0995b8c57aaddb31cf3971f6e","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/57ce484a45b098de417f19265c95c64497782e36","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/919f2ffda03329c9014bedcb3c7789d38660c9ed","tags":[]},{"url":"https://github.com/asterisk/asterisk/commit/dafff9fb60281817225f1ce6371a5aa2fbb967a4","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/20.20.1","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/21.12.3","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/22.10.1","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/23.4.1","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/certified-20.7-cert11","tags":[]},{"url":"https://github.com/asterisk/asterisk/releases/tag/certified-22.8-cert3","tags":[]},{"url":"https://github.com/asterisk/asterisk/security/advisories/GHSA-8jw3-ccr9-xrmf","tags":[]},{"url":"https://github.com/asterisk/asterisk/tree/24.0.0-pre1","tags":[]}],"hasPoc":true,"ai":null}
