CVE-2024-38080 is an elevation of privilege vulnerability in Windows Hyper-V caused by an integer overflow condition. Successful exploitation allows an authenticated attacker to elevate privileges on a vulnerable Windows system and obtain execution in the security context of the SYSTEM account. The vulnerability affects the Hyper-V component and was reported as actively exploited in the wild at the time of disclosure.

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.
