{"id":"CVE-2017-3225","url":"https://www.cyber-defence.io/tools/cve/CVE-2017-3225","generatedAt":"2026-10-29T04:39:04.168Z","title":"For devices utilizing this environment encryption mode, U-Boot's use of a zero initialization vector may allow attacks against the underlying cryptographic implementation and allow an attacker to decrypt the data.","description":"Das U-Boot is a device bootloader that can read its configuration from an AES encrypted file. For devices utilizing this environment encryption mode, U-Boot's use of a zero initialization vector may allow attacks against the underlying cryptographic implementation and allow an attacker to decrypt the data. Das U-Boot's AES-CBC encryption feature uses a zero (0) initialization vector. This allows an attacker to perform dictionary attacks on encrypted data produced by Das U-Boot to learn information about the encrypted data.","published":"2018-07-24T15:29:01.000Z","lastModified":"2026-06-17T01:17:46.000Z","status":"Modified","sourceIdentifier":"cret@cert.org","cvss":{"version":"3.0","score":4.6,"severity":"MEDIUM","vector":"CVSS:3.0/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"cwe":["CWE-329","CWE-310"],"affected":["denx/u-boot"],"epss":{"score":0.00309,"percentile":0.23685,"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":"low","text":"Lower severity and a low EPSS score (0.31%).
