CVSS v3.1

Official Description

The TCP/IP implementation in Microsoft Windows Vista Gold, SP1, and SP2 and Server 2008 Gold and SP2, when IPv6 is enabled, does not properly perform bounds checking on ICMPv6 Router Advertisement packets, which allows remote attackers to execute arbitrary code via crafted packets, aka "ICMPv6 Router Advertisement Vulnerability."

Technical Analysis

CVE-2010-0239 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.

A proof-of-concept (PoC) exploit exists for CVE-2010-0239. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
