CVE-2024-45234Network attack vector

Route-validation crash via non-canonical signed attributes

Published Aug 24, 2024 · Updated Nov 3, 2025

Denial of service in NIC Mexico FORT Validator before 1.6.3 allows remote attackers to crash route-origin validation via crafted RPKI objects. The BER decoder accepts non-canonical signedAttrs in an ROA or Manifest and passes them to a DER-only code path that panics on the encoding. The object must come from a malicious repository beneath a trusted Trust Anchor; the resulting crash interrupts Route Origin Validation and can undermine routing decisions.
