(fixed in 12.1.2 HF2), or 13.0.0-13.0.0 HF2 (fixed in 13.0.0 HF3) a virtual server configured with a Client SSL profile may be vulnerable to an Adaptive Chosen Ciphertext attack (AKA Bleichenbacher attack) against RSA, which when exploited, may result in plaintext recovery of encrypted messages and/or a Man-in-the-middle (MiTM) attack, despite the attacker not having gained access to the server's private key itself, aka a ROBOT attack.","dates":{"published":"2017-11-17T19:00:00.000Z","modified":"2024-08-05T15:18:49.948Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.4,"severity":"high","version":"3.0","versionLabel":"v3.0","source":"NVD","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.0","versionLabel":"v3.0","source":"NVD","score":7.4,"severity":"high","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/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:P/I:N/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.19637,"percentile":0.97366,"severity":"medium","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-19T00:00:00.000Z","baselineScore":0.19637},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.19553,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.19553,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.19553,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.19553,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.19553,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.15063,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.19637,"percentile":0.97366}],"last30":[{"date":"2026-09-19T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.15063,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.19637,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.19637,"percentile":nu
