CVSS: 3.3EPSS: 0%CPEs: 1EXPL: 0CVE-2022-23649 – Improper Certificate Validation in Cosign
https://notcve.org/view.php?id=CVE-2022-23649
Cosign provides container signing, verification, and storage in an OCI registry for the sigstore project. Prior to version 1.5.2, Cosign can be manipulated to claim that an entry for a signature exists in the Rekor transparency log even if it doesn't. This requires the attacker to have pull and push permissions for the signature in OCI. This can happen with both standard signing with a keypair and "keyless signing" with Fulcio. If an attacker has access to the signature in OCI, they can manipulate cosign into believing the entry was stored in Rekor even though it wasn't. • https://github.com/sigstore/cosign/commit/96d410a6580e4e81d24d112a0855c70ca3fb5b49 https://github.com/sigstore/cosign/security/advisories/GHSA-ccxc-vr6p-4858 • CWE-295: Improper Certificate Validation •
