{"schemaVersion":3,"id":"CVE-2025-20139","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A vulnerability in chat messaging features of Cisco Enterprise Chat and Email (ECE) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition.\n\n This vulnerability is due to improper validation of user-supplied input to chat entry points. An attacker could exploit this vulnerability by sending malicious requests to a messaging chat entry point in the affected application. A successful exploit could allow the attacker to cause the application to stop responding, resulting in a DoS condition. The application may not recover on its own and may need an administrator to manually restart services to recover.","dates":{"published":"2025-04-02T16:16:17.546Z","modified":"2025-04-02T16:33:45.699Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.5,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00653,"percentile":0.50337,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":0.010999999999999985,"baselineDate":"2026-09-19T00:00:00.000Z","baselineScore":0.00642},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00653,"percentile":0.50337}],"last30":[{"date":"2026-09-19T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00642,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00653,"percentile":null},{"date":"2026-10-10T00:00
