CVE-2009-0418

26
FAUCET Score

CVE-2009-0418 describes a critical vulnerability in the IPv6 Neighbor Discovery Protocol (NDP) implementation within HP-UX operating systems (B.11.11, B.11.23, and B.11.31). This flaw allows remote attackers to manipulate the Forward Information Base (FIB) by sending spoofed NDP messages, leading to a denial of service, unauthorized network traffic interception, and potentially arbitrary code execution. With a CVSS score of 9.3 (Critical), the vulnerability is easily exploitable over the network with medium attack complexity, posing significant risks to confidentiality, integrity, and availability. Despite its severity, there is no evidence of active exploitation, publicly available exploit code, or significant community discussion or media coverage, suggesting it is not currently a high-profile threat.
