{"schemaVersion":3,"id":"CVE-2022-29957","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"The Emerson DeltaV Distributed Control System (DCS) through 2022-04-29 mishandles authentication. It utilizes several proprietary protocols for a wide variety of functionality. These protocols include Firmware upgrade (18508/TCP, 18518/TCP); Plug-and-Play (18510/UDP); Hawk services (18507/UDP); Management (18519/TCP); Cold restart (18512/UDP); SIS communications (12345/TCP); and Wireless Gateway Protocol (18515/UDP). None of these protocols have any authentication features, allowing any attacker capable of communicating with the ports in question to invoke (a subset of) desired functionality.","dates":{"published":"2022-07-26T21:14:50.000Z","modified":"2024-08-03T06:33:43.178Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.8,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"NVD","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7.8,"severity":"high","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00218,"percentile":0.11629,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.00218},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00218,"percentile":0.11629}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00218,"percentile":null},{"date":"2026-10-13T00:00:00.0
