{"schemaVersion":3,"id":"CVE-2017-8415","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"An issue was discovered on D-Link DCS-1100 and DCS-1130 devices. The device has a custom telnet daemon as a part of the busybox and retrieves the password from the shadow file using the function getspnam at address 0x00053894. Then performs a crypt operation on the password retrieved from the user at address 0x000538E0 and performs a strcmp at address 0x00053908 to check if the password is correct or incorrect. However, the /etc/shadow file is a part of CRAM-FS filesystem which means that the user cannot change the password and hence a hardcoded hash in /etc/shadow is used to match the credentials provided by the user. This is a salted hash of the string \"admin\" and hence it acts as a password to the device which cannot be changed as the whole filesystem is read only.","dates":{"published":"2019-07-02T20:13:08.000Z","modified":"2024-08-05T16:34:22.971Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":10,"severity":"high","version":"2.0","versionLabel":"v2.0","source":"NVD","vector":"AV:N/AC:L/Au:N/C:C/I:C/A:C","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":9.8,"severity":"critical","vector":"CVSS:3.1/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":10,"severity":"high","vector":"AV:N/AC:L/Au:N/C:C/I:C/A:C","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.0393,"percentile":0.90246,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-19T00:00:00.000Z","baselineScore":0.0393},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.0393,"percentile":0.90246}],"last30":[{"date":"2026-09-19T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.0393,"percentile":null},{"date":"2
