CVE-2024-56170 — A validation integrity issue was discovered in Fort through 1.6.4 before 2.0.0

Medium CVSS 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 As such, it's prone to a rollback to a previous version if it's served a valid outdated manifest. This leads to outdated route origin validation.

General vulnerability remediation

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Confirm the affected component, deployment paths, reachable interfaces, and enabled features from inventories and configuration, without probing production destructively.
  • Compare the advisory's affected conditions with the repository lockfiles, build manifests, artifacts, and runtime inventory.
  • Identify data sensitivity, trust boundaries, and privilege level for every confirmed affected deployment.

Remediate safely

  • Apply a vendor-supported fix or remove the affected component or feature; record the selected change and its source in the repository.
  • Update direct and transitive dependency locks, generated artifacts, deployment manifests, and asset inventories together.
  • Add a regression test for the documented unsafe condition using inert inputs and preserve rollback instructions.
