{"schemaVersion":3,"id":"CVE-2021-1528","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A vulnerability in the CLI of Cisco SD-WAN Software could allow an authenticated, local attacker to gain elevated privileges on an affected system. This vulnerability exists because the affected software does not properly restrict access to privileged processes. An attacker could exploit this vulnerability by invoking a privileged process in the affected system. A successful exploit could allow the attacker to perform actions with the privileges of the root user.","dates":{"published":"2021-06-04T16:45:40.937Z","modified":"2024-11-07T22:09:53.223Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.8,"severity":"high","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:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":7.8,"severity":"high","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7.8,"severity":"high","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"2.0","versionLabel":"v2.0","source":"NVD","score":7.2,"severity":"high","vector":"AV:L/AC:L/Au:N/C:C/I:C/A:C","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00248,"percentile":0.14984,"severity":"low","asOf":"2026-10-18T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-18T00:00:00.000Z","baselineScore":0.00248},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00248,"percentile":0.14984}],"last30":[{"date":"2026-09-18T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00248,"percentile":null},{"date":"20
