Command Injection can occur via the dest_host parameter in a diag_action=ping request to a GponForm/diag_Form URI. Because the router saves ping results in /tmp and transmits them to the user when the user revisits /diag.html, it's quite simple to execute commands and retrieve their output.","published":"2018-05-04T03:29:00.000Z","lastModified":"2026-06-17T01:34:10.000Z","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":["dasannetworks/gpon router firmware"],"epss":{"score":0.99949,"percentile":0.99973,"date":"2026-10-27","history":[]},"kev":{"listed":true,"dateAdded":"2022-03-31","dueDate":"2022-04-21","knownRansomwareCampaignUse":"Known","notes":"The impacted product is end-of-life and should be disconnected if still in use.\nhttps://nvd.nist.gov/vuln/detail/CVE-2018-10562"},"exploits":{"count":1,"verified":false,"firstPublished":"2018-05-03","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":44576,"kind":"exploit","title":"GPON Routers - Authentication Bypass / Command Injection","url":"https://www.exploit-db.com/exploits/44576","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/hardware/remote/44576.sh","file":"exploits/hardware/remote/44576.sh","published":"2018-05-03","added":"2018-05-03","updated":"2018-05-03","author":"vpnmentor","type":"remote","platform":"hardware","port":null,"verified":false,"codes":["CVE-2018-10562","CVE-2018-10561"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":"https://www.vpnmentor.com/blog/critical-vulnerability-gpon-router/"}]},"verdict":{"level":"urgent","text":"Known to be exploited in the wild (CISA KEV, CISA remediation deadline 21 April 2022).
