CWE-94Published: February 10, 2010· Updated: Jun 16, 2026
10.0
CVSS v3.1
Official Description
The TCP/IP implementation in Microsoft Windows Vista Gold, SP1, and SP2 and Server 2008 Gold and SP2, when a custom network driver is used, does not properly handle local fragmentation of Encapsulating Security Payload (ESP) over UDP packets, which allows remote attackers to execute arbitrary code via crafted packets, aka "Header MDL Fragmentation Vulnerability."
Technical Analysis
CVE-2010-0240 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.
