The issue occurs when the attacker sends an arbitrary input to a \"PingTest\" device common gateway interface that could lead to common injection. An attacker who successfully triggers the command injection could achieve full system compromise. Later, it was independently found that these are also affected: DIR-855L, DAP-1533, DIR-862L, DIR-615, DIR-835, and DIR-825.","published":"2019-09-27T12:15:10.000Z","lastModified":"2026-06-17T02:22:58.000Z","status":"Analyzed","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","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"},"cwe":["CWE-78"],"affected":["dlink/dir-655 firmware","dlink/dir-866l firmware","dlink/dir-652 firmware","dlink/dhp-1565 firmware","dlink/dir-855l firmware","dlink/dap-1533 firmware","dlink/dir-862l firmware","dlink/dir-615 firmware","dlink/dir-835 firmware","dlink/dir-825 firmware"],"epss":{"score":0.99996,"percentile":0.99989,"date":"2026-10-30","history":[]},"kev":{"listed":true,"dateAdded":"2022-03-25","dueDate":"2022-04-15","knownRansomwareCampaignUse":"Unknown","notes":"The impacted product is end-of-life and should be disconnected if still in use.\nhttps://nvd.nist.gov/vuln/detail/CVE-2019-16920"},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"Known to be exploited in the wild (CISA KEV, CISA remediation deadline 15 April 2022).
