{"cve":"CVE-2017-8417","nvd":{"published":"2019-07-02T21:15:10.633","modified":"2026-06-17T01:26:21.393","status":"Modified","description":"An issue was discovered on D-Link DCS-1100 and DCS-1130 devices. The device requires that a user logging into the device provide a username and password. However, the device allows D-Link apps on the mobile devices and desktop to communicate with the device without any authentication. As a part of that communication, the device uses custom version of base64 encoding to pass data back and forth between the apps and the device. However, the same form of communication can be initiated by any process including an attacker process on the mobile phone or the desktop and this allows a third party to retrieve the device's password without any authentication by sending just 1 UDP packet with custom base64 encoding. The severity of this attack is enlarged by the fact that there more than 100,000 D-Link devices out there.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-255"],"references":["http://packetstormsecurity.com/files/153226/Dlink-DCS-1130-Command-Injection-CSRF-Stack-Overflow.html","https://github.com/ethanhunnt/IoT_vulnerabilities/blob/master/Dlink_DCS_1130_security.pdf","https://seclists.org/bugtraq/2019/Jun/8","http://packetstormsecurity.com/files/153226/Dlink-DCS-1130-Command-Injection-CSRF-Stack-Overflow.html","https://github.com/ethanhunnt/IoT_vulnerabilities/blob/master/Dlink_DCS_1130_security.pdf"],"products":["dlink:dcs-1100_firmware","dlink:dcs-1130_firmware"],"source":"nvd","synced_at":"2026-10-19T20:57:00.690689396+00:00"},"epss":{"cve":"CVE-2017-8417","score":0.03753,"percentile":0.89885,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
