CVE-2014-4076 is a local privilege-escalation vulnerability in the TCP/IP implementation of Microsoft Windows Server 2003 SP2. A local user can exploit the IPv4 or IPv6 driver through a crafted IOCTL call. The vulnerability involves a NULL-pointer dereference and can enable escalation to SYSTEM privileges. APT28 has exploited this vulnerability for privilege escalation.

This repository contains a single Metasploit module (ms14_070_tcpip_ioctl.rb) that exploits a local privilege escalation vulnerability (CVE-2014-4076) in the Microsoft Windows TCP/IP driver (tcpip.sys) on Windows Server 2003 SP2 (32-bit). The exploit works by opening a handle to the \\.\tcp device and sending a specially crafted IOCTL to trigger a NULL pointer dereference, allowing the attacker to execute custom shellcode in kernel mode. The module includes logic to check the target's architecture and driver version, and only attempts exploitation if the system is vulnerable. Upon successful exploitation, the module elevates the attacker's privileges to SYSTEM and executes a user-supplied payload (typically Meterpreter shellcode). The code is written in Ruby and is designed to be run within the Metasploit Framework. The only fingerprintable endpoints are the device path (\\.\tcp) and the driver file path (%WINDIR%\system32\drivers\tcpip.sys).
