{"schemaVersion":3,"id":"CVE-2020-3520","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A vulnerability in Cisco Data Center Network Manager (DCNM) Software could allow an authenticated, local attacker to obtain confidential information from an affected device. The vulnerability is due to insufficient protection of confidential information on an affected device. An attacker at any privilege level could exploit this vulnerability by accessing local filesystems and extracting sensitive information from them. A successful exploit could allow the attacker to view sensitive data, which they could use to elevate their privilege.","dates":{"published":"2020-08-26T16:15:29.248Z","modified":"2024-11-13T18:13:33.343Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":5.5,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","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},{"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},{"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":0.00287,"percentile":0.19858,"severity":"low","asOf":"2026-10-18T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-18T00:00:00.000Z","baselineScore":0.00287},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00287,"percentile":0.19858}],"last30":[{"date":"2026-09-18T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00287,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00287,"percentile":null},{
