CVE-2014-4113 is a local elevation-of-privilege vulnerability in the Windows kernel-mode driver win32k.sys affecting multiple Microsoft Windows versions, including Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1. The flaw allows a local user to run a crafted application that triggers vulnerable win32k.sys behavior and executes code in kernel context, resulting in privilege escalation. Reporting on in-the-wild exploitation indicates the exploit was used as a post-compromise step rather than an initial access vector. Technical analysis described exploitation approaches that invoked a kernel-mode callback and then overwrote the current process token to obtain SYSTEM privileges, using null-page techniques on 32-bit systems or mapped-page techniques on 64-bit systems.

This repository contains a single Metasploit module: 'ms14_058_track_popup_menu.rb', which exploits a NULL pointer dereference vulnerability (CVE-2014-4113) in the Windows kernel driver win32k.sys. The exploit is local and requires an existing Meterpreter session on a vulnerable Windows system. It supports both x86 and x64 architectures and targets Windows XP SP3, Windows 2003 SP2, Windows 7 SP1, Windows 2008, and Windows 2008 R2 SP1. The module checks the version of win32k.sys to determine if the target is vulnerable, and then uses Reflective DLL Injection to execute a payload (typically a Meterpreter shell) as SYSTEM. The exploit does not support Windows 8/8.1 or WOW64 sessions. The main file is written in Ruby and is structured as a standard Metasploit local privilege escalation module.
This repository provides a working exploit and trigger for CVE-2014-4113, a local privilege escalation vulnerability in Microsoft Windows (notably Windows 7 SP1 x86). The structure consists of two main Visual Studio C++ projects: 'Exploit' and 'Trigger'. - The 'Trigger' project (Trigger/Trigger/Trigger.cpp) sets up the conditions to trigger the vulnerability by manipulating window messages and menu structures, using hooks and custom window procedures. - The 'Exploit' project (Exploit/Exploit/Exploit.cpp) contains the actual privilege escalation logic. It includes a token stealing shellcode that manipulates kernel structures to assign the SYSTEM process token to the current process. Upon success, it spawns calc.exe as SYSTEM, demonstrating code execution with elevated privileges. The exploit is operational and requires local access to a vulnerable Windows system. It does not use any network endpoints, but interacts with system files and processes. The code is well-commented and provides a clear demonstration of the exploit technique for CVE-2014-4113.
