CVE-2010-0232 is a local privilege escalation vulnerability in the Microsoft Windows kernel affecting Windows NT 3.1 through Windows 7 on 32-bit x86 systems where support for 16-bit applications is enabled. The flaw exists in the handling of BIOS calls associated with the Windows Virtual DOS Machine (NTVDM) subsystem. Specifically, the kernel does not properly validate certain BIOS calls when a user crafts a malicious VDM_TIB structure in the Thread Environment Block (TEB) and invokes NtVdmControl to start NTVDM. This can trigger improperly handled exceptions in the general protection fault handler, nt!KiTrap0D, resulting in elevation of privilege. Microsoft refers to this as the Windows Kernel Exception Handler Vulnerability.

This repository contains a working local privilege escalation exploit for CVE-2010-0232, targeting a flaw in the #GP trap handler (KiTrap0D) in 32-bit x86 versions of Microsoft Windows NT (from NT 3.1 up to Windows 7). The exploit is implemented in C across two main files: vdmallowed.c (the orchestrator) and vdmexploit.c (the payload and VDM routines). The exploit works by manipulating the Virtual DOS Machine (NTVDM) subsystem and the VDM_TIB structure to trick the kernel into switching the kernel stack to an attacker-controlled address, allowing arbitrary code execution in kernel mode. The exploit ultimately spawns a SYSTEM shell (cmd.exe) for the attacker. The Makefile is used to build the exploit components. The repository also includes detailed advisories and documentation explaining the vulnerability, its exploitation, and mitigations. The attack vector is local, requiring the attacker to execute code on the target system with NTVDM enabled. Notable fingerprintable endpoints include references to system binaries (cmd.exe, debug.exe) and the use of the NTDLL library for direct system calls.
