CVE-2024-45235: Nicmx Fort Validator

High severity, CVSS 7.5. EPSS: 0.3% 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) a resource certificate containing an Authority Key Identifier extension that lacks the keyIdentifier field. Fort references this pointer without sanitizing it first. Because Fort is an RPKI Relying Party, a crash 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)
