{"schemaVersion":3,"id":"CVE-2021-1407","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Multiple vulnerabilities in the web-based management interface of Cisco Unified Communications Manager (Unified CM), Cisco Unified Communications Manager IM &amp; Presence Service (Unified CM IM&amp;P), Cisco Unified Communications Manager Session Management Edition (Unified CM SME), and Cisco Unity Connection could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against an interface user. These vulnerabilities exist because the web-based management interface does not properly validate user-supplied input. An attacker could exploit these vulnerabilities by persuading an interface user to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive browser-based information.","dates":{"published":"2021-04-08T04:06:03.200Z","modified":"2024-11-08T23:28:40.089Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.1,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":6.1,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":6.1,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/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":0.00823,"percentile":0.56595,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-19T00:00:00.000Z","baselineScore":0.00823},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00823,"percentile":0.56595}],"last30":[{"date":"2026-09-19T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00823,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00823,"percentile":nu
