CVE-2024-45234

Severity CVSS v4.0:
Pending analysis

Description

An issue was discovered in Fort before 1.6.3. A malicious RPKI repository that descends from a (trusted) Trust Anchor can serve (via rsync or RRDP) an ROA or a Manifest containing a signedAttrs encoded in non-canonical form. This bypasses Fort's BER decoder, reaching a point in the code that panics when faced with data not encoded in DER. Because Fort is an RPKI Relying Party, a panic can lead to Route Origin Validation unavailability, which can lead to compromised routing.
