5.6 · MEDIUMOverview
CVE-2021-41087 is a medium-severity vulnerability affecting in-toto in-toto-golang. It was published on September 21, 2021 and has a CVSS 3.1 base score of 5.6 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.6, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
in-toto-golang is a go implementation of the in-toto framework to protect software supply chain integrity. In affected versions authenticated attackers posing as functionaries (i.e., within a trusted set of users for a layout) are able to create attestations that may bypass DISALLOW rules in the same layout. An attacker with access to trusted private keys, may issue an attestation that contains a disallowed artifact by including path traversal semantics (e.g., foo vs dir/../foo). Exploiting this vulnerability is dependent on the specific policy applied. The problem has been fixed in version 0.3.0.
Remediation
Check the references section for vendor advisories and patches from in-toto. Update in-toto-golang to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
