{"schema":"threatline.record/2","record":{"id":"CVE-2026-57203","aliases":["GHSA-xgj6-2gc5-5x9c"],"summary":"Asterisk: Local privilege escalation through ast_loggrabber's world-writable helper location","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, `ast_loggrabber` executes a `Python script` from the world-writable `/tmp` directory. An attacker already authorized to open a shell session on the Asterisk server may place a malicious script there and gain elevated privileges or execute code when an administrator runs `ast_loggrabber` as a user with elevated privileges. 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-2026-57203","source_modified_at":"2026-10-27T21:48:40.078Z","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-2026-57203","source_modified_at":"2026-10-27T21:48:40.078Z","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":6.9,"severity":"Medium","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-27T21:48:40.078Z","modified_at":"2026-10-27T21:48:40.078Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-57203","fetched_at":"2026-10-28T01:10:53.534015Z","source_modified_at":"2026-10-27T21:48:40.078Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/asterisk/asterisk/security/advisories/GHSA-xgj6-2gc5-5x9c","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/022407ec47adebe27b7ec8bcf5626e5a02fe1551","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/a51c4e3d6bccce4bc4226c43e78952573a62f165","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/ba8e5bdecd5280fc0ab230df59e41ea21b3a052f","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/bd63fe121d0e86867863bd98b5771e592273b035","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/c0fc2ae54cb6289a48a80333432f5fdf5a40c7de","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/f18ac4c964781f671e400342790bf40679698067","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":"2026-10-27T21:48:40.078Z","content_hash":"c94048e6d4175e5e5b0046f4515f30bc2f652a49aa38e68b1a505501967fe830"}}
