{"id":"CVE-2022-0317","aliases":["GHSA-99cg-575x-774p","GO-2022-0294"],"url":"https://o3.security/vulnerability/CVE-2022-0317","summary":"Improper Input Validation in AKPublic.Verify in go-attestation","details":"An improper input validation vulnerability in go-attestation before 0.3.3 allows local users to provide a maliciously-formed Quote over no/some PCRs, causing AKPublic.Verify to succeed despite the inconsistency. Subsequent use of the same set of PCR values in Eventlog.Verify lacks the authentication performed by quote verification, meaning a local attacker could couple this vulnerability with a maliciously-crafted TCG log in Eventlog.Verify to spoof events in the TCG log, hence defeating remotely-attested measured-boot. We recommend upgrading to Version 0.4.0 or above.","published":"2022-02-04T22:33:03.136Z","modified":"2026-08-12T03:51:38.915638841Z","cvss":{"score":4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/google/go-attestation","fixedVersion":"0.4.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/0xxx/CVE-2022-0317.json"},{"type":"ADVISORY","url":"https://github.com/google/go-attestation/security/advisories/GHSA-99cg-575x-774p"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-0317"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:38.915638841Z"}}
