{"schemaVersion":3,"id":"CVE-2019-9950","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Western Digital My Cloud, My Cloud Mirror Gen2, My Cloud EX2 Ultra, My Cloud EX2100, My Cloud EX4100, My Cloud DL2100, My Cloud DL4100, My Cloud PR2100 and My Cloud PR4100 firmware before 2.31.174 is affected by an authentication bypass vulnerability. The login_mgr.cgi file checks credentials against /etc/shadow. However, the \"nobody\" account (which can be used to access the control panel API as a low-privilege logged-in user) has a default empty password, allowing an attacker to modify the My Cloud EX2 Ultra web page source code and obtain access to the My Cloud as a non-Admin My Cloud device user.","dates":{"published":"2019-04-24T17:17:57.000Z","modified":"2024-08-04T22:10:08.903Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":9.8,"severity":"critical","version":"3.0","versionLabel":"v3.0","source":"NVD","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.0","versionLabel":"v3.0","source":"NVD","score":9.8,"severity":"critical","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"2.0","versionLabel":"v2.0","source":"NVD","score":7.5,"severity":"high","vector":"AV:N/AC:L/Au:N/C:P/I:P/A:P","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.02304,"percentile":0.83097,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-20T00:00:00.000Z","baselineScore":0.02304},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.01968,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.02304,"percentile":0.83097}],"last30":[{"date":"2026-09-20T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.01968,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.02304,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.02304,"percentile":n
