{"id":"CVE-2021-3978","details":"When copying files with rsync, octorpki uses the \"-a\" flag 0, which forces rsync to copy binaries with the suid bit set as root. Since the provided service definition defaults to root ( https://github.com/cloudflare/cfrpki/blob/master/package/octorpki.service ) this could allow for a vector, when combined with another vulnerability that causes octorpki to process a malicious TAL file, for a local privilege escalation.","aliases":["GHSA-3pqh-p72c-fj85","GO-2022-0580"],"modified":"2026-04-12T01:58:28.895045Z","published":"2025-01-29T10:15:07.750Z","references":[{"type":"ADVISORY","url":"https://github.com/cloudflare/cfrpki/security/advisories/GHSA-3pqh-p72c-fj85"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/cloudflare/cfrpki","events":[{"introduced":"0"},{"fixed":"667e707530e3a32cfa5f135637a38608300d4c9d"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.4.2"}],"cpe":"cpe:2.3:a:cloudflare:octorpki:*:*:*:*:*:*:*:*","source":"CPE_FIELD"}}],"versions":["1.0.0","1.0.1","1.0.2","1.0.3","v1.1.0","v1.1.1","v1.1.2","v1.1.3","v1.1.4","v1.2.0","v1.2.0-pre","v1.2.1","v1.2.2","v1.3.0","v1.4.1"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2021-3978.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"}]}
