Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of HNAP login requests. The issue results from the lack of proper implementation of the authentication algorithm. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the router. Was ZDI-CAN-9470.","provenance":"source","from":"CVE.org"},"summary":{"text":"A flaw in the handling of HNAP login requests in the D-Link DIR-867, DIR-878, and DIR-882 routers running firmware 1.10B04 stems from an incorrect implementation of the authentication algorithm. An attacker on an adjacent network can exploit it without authenticating or any user interaction, bypassing login to escalate privileges and execute code on the router.","provenance":"ai","model":"claude-haiku-5-5","generatedAt":"2026-10-29T07:15:20Z"},"cvss":{"score":8.8,"severity":"HIGH","version":"3.0","vector":"CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","provenance":"source","from":"CVE.org CNA"},"epss":{"score":0.78408,"percentile":0.99581,"date":"2026-10-29","provenance":"source"},"kev":null,"vulncheckKev":null,"exploited":false,"otx":{"pulseCount":0,"pulses":[],"provenance":"machine"},"cwes":[{"id":"CWE-303","name":"Incorrect Implementation of Authentication Algorithm"}],"references":[{"url":"https://www.zerodayinitiative.com/advisories/ZDI-20-267/","tags":["x_refsource_MISC"]},{"url":"https://supportannouncement.us.dlink.com/announcement/publication.aspx?name=SAP10157","tags":["x_refsource_MISC"]}],"techniques":[],"reports":[],"affected":[],"advisories":[],"euvd":{"id":"EUVD-2020-29705","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2020-29705","exploited":false,"exploitedSince":null,"provenance":"source"},"exploits":[],"exploitSources":null,"exploitRefs":[],"flow":[],"timeline":[{"date":"2020-03-23","kind":"published","label":"Published (CVE.org)","url":"https://www.cve.org/CVERecord?id=CVE-2020-8863","provenance":"source"}],"speed":{"daysToPublicExploit":null,"firstExploitFrom":null,"daysToKev":null},"priority":{"score":26.1,"factors":[{"name":"In a KEV catalog","points":0.0,"detail":"not listed"},{"name":"Recent KEV listing","points":0.0,"detail":"not listed"},{"name":"Known ransomware use","points":0.0,"detail":"not known"},{"name":"EPSS percentile","points":19.92,"detail":"percentile 0.9958"},{"name":"Named in threat reports","points":0.0,"detail":"0 reports"},{"name":"Public exploit code","points":0.0,"detail":"none found"},{"name":"Mentioned in OTX pulses","points":0.0,"detail":"0 pulses"},{"name":"CVSS severity","points":6.16,"detail":"base score 8.8"},{"name":"End-of-life product","points":0.0,"detail":"supported or unknown"}]}}
