The know-how protection feature in affected products does not properly update the encryption of existing program blocks when a project file is updated.\n\nThis could allow attackers with access to the project file to recover previous - yet unprotected - versions of the project without the knowledge of the know-how protection password.","dates":{"published":"2023-06-13T08:17:10.136Z","modified":"2024-12-10T13:53:26.912Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.2,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:P/RL:T/RC:C","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":6.2,"severity":"medium","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:P/RL:T/RC:C","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":5.5,"severity":"medium","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.0012,"percentile":0.01722,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-19T00:00:00.000Z","baselineScore":0.0012},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.0012,"percentile":0.01722}],"last30":[{"date":"2026-09-19T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.0012,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.0012,"percentile":null}
