CVE-2016-0095 is a local privilege escalation vulnerability in the kernel-mode driver (win32k.sys) of multiple Microsoft Windows versions, including Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8.1, Windows Server 2012 Gold and R2, Windows RT 8.1, and Windows 10 Gold and 1511. The vulnerability allows a local attacker to execute a crafted application that exploits improper handling of objects in the kernel, resulting in elevation of privileges to SYSTEM.

This repository is a proof-of-concept (PoC) exploit for CVE-2016-0095 (MS16-034), targeting Windows 7 Ultimate x64. The exploit consists of a C file (cve-2016-0095.c) and an x64 assembly file (__asm.asm) containing custom shellcode. The C code allocates a null page, sets up specific memory values to bypass checks, and triggers a vulnerability in the Windows GDI subsystem by manipulating bitmaps and region objects. The shellcode attempts to escalate privileges by modifying the current process's EPROCESS structure to inherit the SYSTEM process's token. After running the exploit, it spawns a command shell (cmd). The exploit must be run locally on a vulnerable system and requires the ability to execute native code. The repository is structured as a simple PoC with clear separation between the exploit logic (C) and the privilege escalation payload (assembly).
