{"schemaVersion":3,"id":"CVE-2021-31850","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A denial-of-service vulnerability in Database Security (DBS) prior to 4.8.4 allows a remote authenticated administrator to trigger a denial-of-service attack against the DBS server. The configuration of Archiving through the User interface incorrectly allowed the creation of directories and files in Windows system directories and other locations where sensitive data could be overwritten. The former could lead to a DoS, whilst the latter could lead to data destruction on the DBS server.","dates":{"published":"2021-12-08T11:00:13.000Z","modified":"2024-08-03T23:10:30.698Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.1,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:N/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":6.1,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:N/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":6.1,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:N/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"2.0","versionLabel":"v2.0","source":"NVD","score":4.9,"severity":"medium","vector":"AV:N/AC:M/Au:S/C:N/I:P/A:P","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00999,"percentile":0.62123,"severity":"low","asOf":"2026-10-18T00:00:00.000Z","change":{"pp":0.032000000000000084,"baselineDate":"2026-09-18T00:00:00.000Z","baselineScore":0.00967},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00999,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00999,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00999,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00999,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00999,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00999,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00999,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00999,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00999,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00999,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00999,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00999,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00999,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00999,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00999,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00999,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00999,"percentile":0.62123}],"last30":[{"date":"2026-09-18T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00967,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00999,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00999,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00999,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00999,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00999,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00999,"
