{"schemaVersion":3,"id":"CVE-2018-0382","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A vulnerability in the session identification management functionality of the web-based interface of Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to hijack a valid user session on an affected system. The vulnerability exists because the affected software does not properly clear previously assigned session identifiers for a user session when a user authenticates to the web-based interface. An attacker could exploit this vulnerability by using an existing session identifier to connect to the software through the web-based interface. Successful exploitation could allow the attacker to hijack an authenticated user's browser session on the system. Versions 8.1 and 8.5 are affected.","dates":{"published":"2019-04-17T21:35:14.963Z","modified":"2024-11-19T19:11:56.991Z","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:N/I:H/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.0","versionLabel":"v3.0","source":"CVE.org","score":5.3,"severity":"medium","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"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:N/I:H/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:N/I:P/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.02041,"percentile":0.80855,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-19T00:00:00.000Z","baselineScore":0.02041},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.02041,"percentile":0.80855}],"last30":[{"date":"2026-09-19T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.02041,"percentile":null},{"date":"
