Details

Improperly Implemented path matching for in-toto-golang ### Impact 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). ### Patches The problem has been fixed in version 0.3.0. ### Workarounds Exploiting this vulnerability is dependent on the specific policy applied. ### For more information If you have any questions or comments about this advisory: * Open an issue in [in-toto-golang](http://github.com/in-toto/in-toto-golang) * Email us at [in-toto-public](mailto:in-toto-public@googlegroups.com) * If this is a sensitive security-relevant disclosure, please send a PGP encrypted email to santiagotorres@purdue.edu or jcappos@nyu.edu
