{"schemaVersion":3,"id":"CVE-2019-18336","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A vulnerability has been identified in SIMATIC S7-300 CPU family (incl. related ET200 CPUs and SIPLUS variants) (All versions < V3.X.17), SIMATIC TDC CP51M1 (All versions < V1.1.8), SIMATIC TDC CPU555 (All versions < V1.1.1), SINUMERIK 840D sl (All versions < V4.8.6), SINUMERIK 840D sl (All versions < V4.94). Specially crafted packets sent to port 102/tcp (Profinet) could cause the affected device to go into defect mode. A restart is required in order to recover the system. Successful exploitation requires an attacker to have network access to port 102/tcp, with no authentication. No user interation is required. At the time of advisory publication no public exploitation of this security vulnerability was known.","dates":{"published":"2020-03-10T19:16:17.000Z","modified":"2026-06-02T18:36:21.590Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.8,"severity":"high","version":"2.0","versionLabel":"v2.0","source":"NVD","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:C","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","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:N/A:H","exploitability":null,"impact":null,"computed":false},{"version":"2.0","versionLabel":"v2.0","source":"NVD","score":7.8,"severity":"high","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:C","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.01716,"percentile":0.77043,"severity":"low","asOf":"2026-10-18T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-18T00:00:00.000Z","baselineScore":0.01716},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.01716,"percentile":0.77043}],"last30":[{"date":"2026-09-18T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.01716,"percentile":null},{"date":"2026-10-08T00:00:00.000
