CWE-20Published: October 3, 2008· Updated: Jun 16, 2026
10.0
CVSS v3.1
Official Description
The IPv6 Neighbor Discovery Protocol (NDP) implementation on IBM zSeries servers does not validate the origin of Neighbor Discovery messages, which allows remote attackers to cause a denial of service (loss of connectivity) or read private network traffic via a spoofed message that modifies the Forward Information Base (FIB), a related issue to CVE-2008-2476.
Technical Analysis
CVE-2008-4404 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
