{"schemaVersion":3,"id":"CVE-2019-1866","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Cisco Webex Business Suite before 39.1.0 contains a vulnerability that could allow an unauthenticated, remote attacker to affect the integrity of the application. The vulnerability is due to improper validation of host header values. An attacker with a privileged network position, either a man-in-the-middle or by intercepting wireless network traffic, could exploit this vulnerability to manipulate header values sent by a client to the affected application. The attacker could cause the application to use input from the header to redirect a user from the Cisco Webex Meetings Online site to an arbitrary site of the attacker's choosing.","dates":{"published":"2020-04-13T16:55:12.071Z","modified":"2024-11-15T17:32:13.647Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":4.3,"severity":"medium","version":"2.0","versionLabel":"v2.0","source":"NVD","vector":"AV:N/AC:M/Au:N/C:N/I:P/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":3.1,"severity":"low","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":3.7,"severity":"low","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"2.0","versionLabel":"v2.0","source":"NVD","score":4.3,"severity":"medium","vector":"AV:N/AC:M/Au:N/C:N/I:P/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00336,"percentile":0.25685,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.00336},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00336,"percentile":0.25685}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00336,"percentile":null},{"date":"2026-10-08T00:00:0
