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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5},"cwes":["CWE-126","CWE-170"],"references":["https://github.com/asterisk/asterisk/commit/07aec894a1fdfa7fa989d3ab40fdf0dcda8005bb","https://github.com/asterisk/asterisk/commit/1039bed76fa3248f58b6880e4b3f1421ef98b01f","https://github.com/asterisk/asterisk/commit/1b2d99d8eb9206d37fd47115996f67fd28bd056f","https://github.com/asterisk/asterisk/commit/3100a0d331affbf0995b8c57aaddb31cf3971f6e","https://github.com/asterisk/asterisk/commit/57ce484a45b098de417f19265c95c64497782e36"],"products":[],"source":"nvd","synced_at":"2026-10-27T17:36:04.447049452+00:00"},"epss":null,"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
