CVE-2014-4076 is a local elevation-of-privilege vulnerability in the Windows TCP/IP stack on Microsoft Windows Server 2003 SP2. The flaw affects tcpip.sys and tcpip6.sys and was addressed by Microsoft in bulletin MS14-070. Available reporting describes the root cause as a NULL-pointer dereference in tcpip.sys that can be triggered through a specially crafted IOCTL request sent to the TCP device via DeviceIoControl. Successful exploitation allows a local user to elevate privileges to a higher integrity context, including SYSTEM.

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).
