{"schemaVersion":3,"id":"CVE-2018-13811","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A vulnerability has been identified in SIMATIC STEP 7 (TIA Portal) (All Versions < V15.1). Password hashes with insufficient computational effort could allow an attacker to access to a project file and reconstruct passwords. The vulnerability could be exploited by an attacker with local access to the project file. No user interaction is required to exploit the vulnerability. The vulnerability could allow the attacker to obtain certain passwords from the project. At the time of advisory publication no public exploitation of this vulnerability was known.","dates":{"published":"2018-12-13T16:00:00.000Z","modified":"2024-08-05T09:14:47.273Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":5.5,"severity":"medium","version":"3.0","versionLabel":"v3.0","source":"NVD","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.0","versionLabel":"v3.0","source":"NVD","score":5.5,"severity":"medium","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","exploitability":null,"impact":null,"computed":false},{"version":"2.0","versionLabel":"v2.0","source":"NVD","score":2.1,"severity":"low","vector":"AV:L/AC:L/Au:N/C:P/I:N/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.0024,"percentile":0.14135,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-19T00:00:00.000Z","baselineScore":0.0024},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00255,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.0024,"percentile":0.14135}],"last30":[{"date":"2026-09-19T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00255,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.0024,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.0024,"percen
