The video-core process incorrectly handles pipelined HTTP requests, which allows successive requests to overwrite the previously parsed HTTP method, 'onmessagecomplete' callback. An attacker can send an HTTP request to trigger this vulnerability.","published":"2018-08-24T00:29:00.000Z","lastModified":"2026-06-17T01:58:00.000Z","status":"Modified","sourceIdentifier":"talos-cna@cisco.com","cvss":{"version":"3.1","score":8.6,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:N"},"cwe":["CWE-444"],"affected":["samsung/sth-eth-250 firmware"],"epss":{"score":0.01251,"percentile":0.69314,"date":"2026-10-28","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (1.25%).
