While the server is hung, print jobs over the network are blocked and the web interface is inaccessible. An attacker can continuously send this malformed request to keep the device inaccessible to legitimate traffic.","published":"2017-11-10T02:29:19.000Z","lastModified":"2026-06-17T01:09:02.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.0","score":7.5,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"cwe":[],"affected":["brother/dcp-j132w firmware"],"epss":{"score":0.59386,"percentile":0.99116,"date":"2026-10-27","history":[{"date":"2026-09-21","score":0.54338,"percentile":0.98987},{"date":"2026-09-22","score":0.59386,"percentile":0.99077}]},"kev":{"listed":false},"exploits":{"count":1,"verified":false,"firstPublished":"2017-11-02","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":43119,"kind":"exploit","title":"Debut Embedded HTTPd 1.20 - Denial of Service","url":"https://www.exploit-db.com/exploits/43119","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/hardware/dos/43119.py","file":"exploits/hardware/dos/43119.py","published":"2017-11-02","added":"2017-11-06","updated":"2017-11-06","author":"z00n","type":"dos","platform":"hardware","port":null,"verified":false,"codes":["CVE-2017-16249"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":null}]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 59.4%, higher than 99% of all known CVEs.
