{"schema":"threatline.record/2","record":{"id":"CVE-2026-57195","aliases":["GHSA-3rhj-hhw7-m6fw"],"summary":"Asterisk: NULL Pointer Dereference in HTTP AMI Digest Authentication","details":"Asterisk is an open source private branch exchange and telephony toolkit. Prior to Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3, a NULL pointer dereference in the `Asterisk Manager Interface (AMI)` may allow an unauthenticated attacker to crash Asterisk when `Digest Authentication` is used via `HTTP`. The Asterisk `HTTP` web server, AMI, and AMI access via `HTTP` must all be enabled; each is disabled by default. The attacker must be able to connect to the `HTTP` server, which binds only to `127.0.0.1` by default even when enabled. 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-2026-57195","source_modified_at":"2026-10-27T21:04:25.747Z","fetched_at":"2026-10-28T01:10:53.534015Z","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-2026-57195","source_modified_at":"2026-10-27T21:04:25.747Z","fetched_at":"2026-10-28T01:10:53.534015Z","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":7.5,"severity":"High","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-27T21:04:25.747Z","modified_at":"2026-10-27T21:04:25.747Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-57195","fetched_at":"2026-10-28T01:10:53.534015Z","source_modified_at":"2026-10-27T21:04:25.747Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/asterisk/asterisk/security/advisories/GHSA-3rhj-hhw7-m6fw","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/10c5b2efcacab03bf04a229f81cc24e76fe42c41","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/362ef847e7e057b7626e476ddcfe7328ea314db4","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/5d5d8d8ef7f16774820b1889ae73d8d2ab14af45","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/87a1f43e4c465b885163665aa89172ed0f392663","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/a1fcfdf9b91ed58cc8fb9da8d135da60bae7345d","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/abba42c58fee2226a709583afdbeec75cf1dde8b","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/fff89162cdd702e8a143701f138edd8dceab154f","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":"2026-10-27T21:04:25.747Z","content_hash":"0410e13f11b7781b658e9a8e45179282919a6426432adabc7212db8deb45e947"}}
