Name of the Vulnerable Software and Affected Versions Fort versions 1.6.4 and earlier, up to but not including 2.0.0

Description A validation integrity issue was discovered in the product. RPKI Relying Parties, such as Fort, are supposed to maintain a backup cache of the remote RPKI data, which 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, leading to incomplete route origin validation data.

Recommendations For Fort versions 1.6.4 and earlier, up to but not including 2.0.0, update to version 2.0.0 or later to resolve the issue. As a temporary workaround, consider implementing an alternative fallback mechanism for handling incomplete or incorrect RPKI data until a patch is available.
