CVE-2009-0418

Estado: ModificadaAlta (9.3)—

The IPv6 Neighbor Discovery Protocol (NDP) implementation in HP HP-UX B.11.11, B.11.23, and B.11.31 does not validate the origin of Neighbor Discovery messages, which allows remote attackers to cause a denial of service (loss of connectivity), read private network traffic, and possibly execute arbitrary code via a spoofed message that modifies the Forward Information Base (FIB), a related issue to CVE-2008-2476.

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).
