{"schemaVersion":3,"id":"CVE-2018-3907","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"An exploitable vulnerability exists in the REST parser of video-core's HTTP server of the Samsung SmartThings Hub STH-ETH-250 - Firmware version 0.20.17. The video-core process incorrectly handles pipelined HTTP requests, which allows successive requests to overwrite the previously parsed HTTP method, 'on_url' callback. An attacker can send an HTTP request to trigger this vulnerability.","dates":{"published":"2018-08-24T00:00:00.000Z","modified":"2024-09-16T23:31:23.692Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":10,"severity":"critical","version":"3.1","versionLabel":"v3.1","source":"NVD","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.0","versionLabel":"v3.0","source":"CVE.org","score":9.1,"severity":"critical","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":10,"severity":"critical","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.0","versionLabel":"v3.0","source":"NVD","score":9.1,"severity":"critical","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"2.0","versionLabel":"v2.0","source":"NVD","score":6.4,"severity":"medium","vector":"AV:N/AC:L/Au:N/C:N/I:P/A:P","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.01435,"percentile":0.72707,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-19T00:00:00.000Z","baselineScore":0.01435},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.01435,"percentile":0.72707}],"last30":[{"date":"2026-09-19T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.01435,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.01435,"percentile":null},{"date
