CVE-2024-45239

Estado: ModificadaAlta (7.5)—

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 null eContent field. Fort dereferences the 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.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

Fort elimina la referencia al puntero sin desinfectarlo primero. Debido a que Fort es una parte de confianza de RPKI, una falla puede provocar que la validación del origen de la ruta no esté disponible, lo que puede comprometer el enrutamiento."
