CVE-2024-45234: Nicmx Fort-Validator

High severity, CVSS 7.5. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Nicmx Fort-Validator: before 1.6.3 (fixed in 1.6.3)
