{"schemaVersion":3,"id":"CVE-2004-2760","aliases":["DEBIAN-CVE-2004-2760"],"status":"published","duplicateOf":null,"title":null,"description":"sshd in OpenSSH 3.5p1, when PermitRootLogin is disabled, immediately closes the TCP connection after a root login attempt with the correct password, but leaves the connection open after an attempt with an incorrect password, which makes it easier for remote attackers to guess the password by observing the connection state, a different vulnerability than CVE-2003-0190.  NOTE: it could be argued that in most environments, this does not cross privilege boundaries without requiring leverage of a separate vulnerability.","dates":{"published":"2008-08-04T10:00:00.000Z","modified":"2024-08-08T01:36:25.323Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.8,"severity":"medium","version":"2.0","versionLabel":"v2.0","source":"NVD","vector":"AV:N/AC:M/Au:N/C:P/I:P/A:P","computed":false,"selection":"backend-summary"},"metrics":[{"version":"2.0","versionLabel":"v2.0","source":"NVD","score":6.8,"severity":"medium","vector":"AV:N/AC:M/Au:N/C:P/I:P/A:P","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.08665,"percentile":0.95106,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.08665},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.08665,"percentile":0.95106}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.08665,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.08665,"percentile
