{"schemaVersion":3,"id":"CVE-2018-3833","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"An exploitable firmware downgrade vulnerability exists in Insteon Hub running firmware version 1013. The firmware upgrade functionality, triggered via PubNub, retrieves signed firmware binaries using plain HTTP requests. The device doesn't check the firmware version that is going to be installed and thus allows for flashing older firmware images. To trigger this vulnerability, an attacker needs to impersonate the remote server 'cache.insteon.com' and serve any signed firmware image.","dates":{"published":"2018-08-23T14:00:00.000Z","modified":"2024-09-17T02:26:41.031Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":8.6,"severity":"high","version":"3.0","versionLabel":"v3.0","source":"CVE.org","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.0","versionLabel":"v3.0","source":"CVE.org","score":8.6,"severity":"high","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.0","versionLabel":"v3.0","source":"NVD","score":8.6,"severity":"high","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:N","exploitability":null,"impact":null,"computed":false},{"version":"2.0","versionLabel":"v2.0","source":"NVD","score":5,"severity":"medium","vector":"AV:N/AC:L/Au:N/C:N/I:P/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.01119,"percentile":0.65837,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.01119},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.01119,"percentile":0.65837}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.01119,"percentile":null},{"date":"2026-10-05T00:00:
