CVE-2024-56170

Estado: AnalizadaMedia (5.3)—

A validation integrity issue was discovered in Fort through 1.6.4 before 2.0.0. RPKI manifests are listings of relevant files that clients are supposed to verify. Assuming everything else is correct, the most recent version of a manifest should be prioritized over other versions, to prevent replays, accidental or otherwise. Manifests contain the manifestNumber and thisUpdate fields, which can be used to gauge the relevance of a given manifest, when compared to other manifests. The former is a serial-like sequential number, and the latter is the date on which the manifest was created.

However, the product does not compare the up-to-dateness of the most recently fetched manifest against the cached manifest. As such, it's prone to a rollback to a previous version if it's served a valid outdated manifest. This leads to outdated route origin validation.

Suponiendo que todo lo demás sea correcto, se debe priorizar la versión más reciente de un manifiesto sobre otras versiones, para evitar repeticiones, accidentales o de otro tipo. Los manifiestos contienen los campos manifestNumber y thisUpdate, que se pueden usar para medir la relevancia de un manifiesto determinado, en comparación con otros manifiestos. El primero es un número secuencial de tipo serial y el segundo es la fecha en la que se creó el manifiesto. Sin embargo, el producto no compara la actualidad del manifiesto obtenido más recientemente con el manifiesto almacenado en caché. Como tal, es propenso a una reversión a una versión anterior si se entregó un manifiesto desactualizado válido. Esto conduce a una validación de origen de ruta desactualizada."
