{"schemaVersion":3,"id":"CVE-2018-10990","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"On Arris Touchstone Telephony Gateway TG1682G 9.1.103J6 devices, a logout action does not immediately destroy all state on the device related to the validity of the \"credential\" cookie, which might make it easier for attackers to obtain access at a later time (e.g., \"at least for a few minutes\"). NOTE: there is no documentation stating that the web UI's logout feature was supposed to do anything beyond removing the cookie from one instance of a web browser; a client-side logout action is often not intended to address cases where a person has made a copy of a cookie outside of a browser.","dates":{"published":"2018-05-14T14:00:00.000Z","modified":"2024-08-05T07:54:35.986Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":8,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"NVD","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":8,"severity":"high","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"2.0","versionLabel":"v2.0","source":"NVD","score":7.5,"severity":"high","vector":"AV:N/AC:M/Au:S/C:P/I:P/A:C","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.01073,"percentile":0.64612,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.01073},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.01073,"percentile":0.64612}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.01073,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.01073,"percentile":null},{"da
