The victim must use the command scp -rp to download a file hierarchy containing, anywhere inside, this crafted subdirectory. NOTE: the vendor points out that \"this attack can achieve no more than a hostile peer is already able to achieve within the scp protocol\" and \"utimes does not fail under normal circumstances.","published":"2020-06-01T16:15:14.000Z","lastModified":"2026-10-14T10:17:26.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},"cwe":["CWE-20"],"affected":["openbsd/openssh"],"epss":{"score":0.02232,"percentile":0.82654,"date":"2026-10-26","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 (2.23%).
