CVE-2024-38080 is an elevation-of-privilege vulnerability in Microsoft Windows Hyper-V. Available reporting describes the flaw as an integer overflow in the Hyper-V component that can be exploited to bypass user-mode protections and elevate privileges. Successful exploitation allows an attacker who already has limited access on the target system to escalate from ordinary user permissions to SYSTEM. The vulnerability was addressed by Microsoft in the July 2024 security updates and has been reported as actively exploited in the wild.

This repository contains a proof-of-concept (POC) exploit for CVE-2024-38080, a vulnerability in Microsoft Windows (likely related to Hyper-V and the VidExoBroker device). The main exploit code is in 'poc/main.c', which is a C program designed to be built with Visual Studio (project files are provided). The exploit checks for the presence of a Hyper-V hypervisor, creates a partition, and crafts a large input buffer filled with process handles. It then sends this buffer to the VidExoBroker device using a specific IOCTL code (SEND_IOCTL), while a separate thread listens for a response using another IOCTL (RECV_IOCTL). The exploit is local and requires access to a Windows system with Hyper-V enabled. The code demonstrates the vulnerability but does not include a weaponized or post-exploitation payload. The repository is structured as a typical Visual Studio C project, with one main code file and supporting project/solution files.
