If present with a valid public key, it enables SSH on port 22 with root login. The /config partition is not protected by measured boot, is mutable and unencrypted.\n\nThis enables an attacker with physical access to the device to take out the disk, modify the /config partition using a separate server, then insert it, without the inserted key being flagged as an integrity voilation my measured boot and remote attestation.\n\n### Patches\n\nPatched in 9.4.3-lts\n\n### Workarounds\n\nNone (apart from preventing physical access to the device)","affected":[{"package":{"name":"github.com/lf-edge/eve","ecosystem":"Go","purl":"pkg:golang/github.com/lf-edge/eve"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.0.0-20220708121648-5fef4d92e758"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/02/GHSA-3mq9-xhgq-r7gj/GHSA-3mq9-xhgq-r7gj.json"}}],"references":[{"type":"WEB","url":"https://github.com/lf-edge/eve/security/advisories/GHSA-3mq9-xhgq-r7gj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-43631"},{"type":"WEB","url":"https://github.com/lf-edge/eve/commit/5fef4d92e75838cc78010edaed5247dfbdae1889"},{"type":"WEB","url":"https://github.com/lf-edge/eve/commit/aa3501d6c57206ced222c33aea15a9169d629141"},{"type":"WEB","url":"https://asrg.io/security-advisories/cve-2023-43631"},{"type":"WEB","url":"https://asrg.io/security-advisories/ssh-as-root-unlockable-without-triggering-measured-boot"},{"type":"PACKAGE","url":"https://github.com/lf-edge/eve"}],"database_specific":{"cwe_ids":["CWE-522","CWE-922"],"github_reviewed":true,"github_reviewed_at":"2026-02-04T20:46:16Z","nvd_published_at":null,"severity":"MODERATE"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:P/AC:L/PR:L/UI:N/S:C/C:L/I:H/A:N"}]}
