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.","categories":["Unclassified"],"product":"asterisk","vendor":"asterisk","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-57185","source_modified_at":"2026-10-27T16:40:27.615Z","fetched_at":"2026-10-27T21:14:11.489891Z","product":"asterisk","vendor":"asterisk","versions":[{"version":"< 20.20.1","status":"affected"},{"version":">= 21.0.0-pre1, < 21.12.3","status":"affected"},{"version":">= 22.0.0-pre1, < 22.10.1","status":"affected"},{"version":">= 23.0.0-pre1, < 23.4.1","status":"affected"}],"defaultStatus":null},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-57185","source_modified_at":"2026-10-27T16:40:27.615Z","fetched_at":"2026-10-27T21:14:11.489891Z","product":"certified-asterisk","vendor":"asterisk","versions":[{"version":"< 20.7-cert11","status":"affected"},{"version":">= 22.8-cert1-pre1, < 22.8-cert3","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-27T16:40:27.615Z","modified_at":"2026-10-27T16:40:27.615Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-57185","fetched_at":"2026-10-27T21:14:11.489891Z","source_modified_at":"2026-10-27T16:40:27.615Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/asterisk/asterisk/security/advisories/GHSA-8jw3-ccr9-xrmf","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/07aec894a1fdfa7fa989d3ab40fdf0dcda8005bb","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/1039bed76fa3248f58b6880e4b3f1421ef98b01f","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/1b2d99d8eb9206d37fd47115996f67fd28bd056f","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/3100a0d331affbf0995b8c57aaddb31cf3971f6e","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/57ce484a45b098de417f19265c95c64497782e36","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/919f2ffda03329c9014bedcb3c7789d38660c9ed","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/dafff9fb60281817225f1ce6371a5aa2fbb967a4","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/releases/tag/20.20.1","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/releases/tag/21.12.3","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/releases/tag/22.10.1","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/releases/tag/23.4.1","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/releases/tag/certified-20.7-cert11","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/releases/tag/certified-22.8-cert3","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/tree/24.0.0-pre1","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-27T16:40:27.615Z","content_hash":"944b9bda6370c8bb0629826106952977944ca903254a9035cef577845209c50c"}}
