{"schema":"threatline.record/2","record":{"id":"CVE-2026-77056","aliases":[],"summary":"Use of Default Credentials in boneIO","details":"boneIO black_debian_images ships with a Mosquitto MQTT broker that uses the same default credentials on all devices. These credentials are publicly documented on github, and there is no indication in the instructions to change them. A remote attacker can use them to gain full read and write access to the broker, allowing control of connected relays, blinds, and gates, and injection of fake entities into a linked Home Assistant installation.\n\nThis issue was fixed in version 1.6.0 of the image: MQTT passwords are generated per device at first boot. Devices upgraded from earlier versions keep their existing broker credentials; from boneio 1.6.0 the web panel reports credentials that are still the published defaults, and the owner has to change them.","categories":["Unclassified"],"product":"black_debian_images","vendor":"boneIO","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-77056","source_modified_at":"2026-10-26T16:46:44.867Z","fetched_at":"2026-10-26T19:10:57.178988Z","product":"black_debian_images","vendor":"boneIO","versions":[{"status":"affected","version":"1.2.0","lessThan":"1.6.0","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-77056","source_modified_at":"2026-10-26T16:46:44.867Z","fetched_at":"2026-10-26T19:10:57.178988Z","package":{"name":"black_debian_images","ecosystem":null},"version":"1.6.0","basis":"first unaffected version stated in the CVE record"}],"cvss":7.1,"severity":"High","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-26T14:45:53.279Z","modified_at":"2026-10-26T16:46:44.867Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-77056","fetched_at":"2026-10-26T19:10:57.178988Z","source_modified_at":"2026-10-26T16:46:44.867Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://cert.pl/en/posts/2026/10/CVE-2026-77052","tags":["third-party-advisory"]},{"source":"CVE List","url":"https://boneio.eu/en/docs/black","tags":["product"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-26T16:25:44.166478Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-26T16:46:44.867Z","content_hash":"08bd05ef90e5f7409efcfe6a3b9d00127246959ea1b247b1bf59e00828aee574"}}
