{"schemaVersion":3,"id":"CVE-2018-16946","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"LG LNB*, LND*, LNU*, and LNV* smart network camera devices have broken access control. Attackers are able to download /updownload/t.report (aka Log & Report) files and download backup files (via download.php) without authenticating. These backup files contain user credentials and configuration information for the camera device. An attacker is able to discover the backup filename via reading the system logs or report data, or just by brute-forcing the backup filename pattern. It may be possible to authenticate to the admin account with the admin password.","dates":{"published":"2018-09-12T01:00:00.000Z","modified":"2024-08-05T10:39:57.673Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.5,"severity":"high","version":"3.0","versionLabel":"v3.0","source":"NVD","vector":"CVSS:3.0/AV:N/AC:L/PR:N/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":7.5,"severity":"high","vector":"CVSS:3.0/AV:N/AC:L/PR:N/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":5,"severity":"medium","vector":"AV:N/AC:L/Au:N/C:P/I:N/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.09348,"percentile":0.95378,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":2.5149999999999992,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.06833},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.06833,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.09348,"percentile":0.95378}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.06833,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.09348,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.09348,"
