Vulnerability details
A validation integrity issue was discovered in Fort through 1.6.4 before 2.0.0. RPKI Relying Parties (such as Fort) are supposed to maintain a backup cache of the remote RPKI data. This can be employed as a fallback in case a…

new fetch fails or yields incorrect files. However, the product currently uses its cache merely as a bandwidth saving tool (because fetching is performed through deltas). If a fetch fails midway or yields incorrect files, there is no viable fallback. This leads to incomplete route origin validation data.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Proper validation of integrity check values is required for reliable tamper detection, directly reducing undetected modification risks.
Requires validation of integrity check values on every resolution response, directly mitigating tampered or corrupted DNS data.
Control mandates proper validation of integrity values (checksums) on prepared data, making flawed validation of those checks ineffective for attackers.
Requires use of proper integrity verification tools, reducing the chance an incorrect check value is accepted.
Requires proper validation of integrity mechanisms, directly mitigating flawed check-value handling.
