CVE-2019-1215 is an elevation of privilege vulnerability in Microsoft Windows due to improper handling of objects in memory by the ws2ifsl.sys (Winsock) driver. An attacker who successfully exploits this vulnerability could execute arbitrary code in kernel mode, allowing them to install programs, view, change, or delete data, or create new accounts with full user rights. The vulnerability is distinct from other similar privilege escalation issues in Windows (e.g., CVE-2019-1253, CVE-2019-1278, CVE-2019-1303).

This repository contains a working local privilege escalation exploit for CVE-2019-1215, a use-after-free vulnerability in the ws2ifsl.sys driver on Windows 10 19H1 x64 (build 18362). The main exploit logic is implemented in 'exploit.cpp', which is a C++ file designed to be built with Visual Studio. The exploit works by leveraging the UAF bug in the driver to gain arbitrary kernel read/write, then locates and manipulates the current process token to escalate privileges. It injects custom shellcode into the winlogon.exe process to spawn a SYSTEM-level cmd.exe. The repository includes Visual Studio project files for building the exploit, and a README describing the vulnerability and usage. The exploit is operational and demonstrates a real-world local privilege escalation attack, requiring local access to the target system.
