CVE-2024-7479 is a privilege escalation vulnerability in TeamViewer Remote Clients for Windows prior to version 15.58.4. The vulnerability arises from improper verification of cryptographic signatures during the installation of a VPN driver via the TeamViewer_service.exe component. This flaw allows a local unprivileged attacker to bypass signature checks and install arbitrary drivers, potentially leading to privilege escalation.

This repository provides a working proof-of-concept exploit for CVE-2024-7479, a vulnerability in TeamViewer for Windows (tested on version 15.57.5) that allows improper signature verification during driver installation. The main exploit script, CVE-2024-7479_PoC.py, implements the TeamViewer IPC protocol to authenticate with the local TeamViewer service (127.0.0.1:5939), and abuses the driver installation process to load an arbitrary (malicious) driver. The exploit orchestrates the renaming and copying of required files (TeamViewerVPN.cat, TeamViewerVPN.inf, dbutil_2_3.sys), sends crafted IPC packets to trigger the vulnerable code path, and finally launches BYOVDKit.exe to gain SYSTEM privileges by opening a SYSTEM shell. The exploit requires local access, a vulnerable TeamViewer installation, and the presence of BYOVDKit.exe and dbutil_2_3.sys in the working directory. The repository includes a README with detailed usage instructions and references, a LICENSE file, and a requirements.txt specifying Python dependencies.
This repository provides a proof-of-concept (PoC) exploit for CVE-2024-7479 and CVE-2024-7481, which are local privilege escalation vulnerabilities in TeamViewer for Windows. The exploit targets the TeamViewer SYSTEM service (TeamViewer_service.exe), which listens for IPC connections on localhost TCP port 5939. By spoofing the authentication handshake and sending a specially crafted IPC message, an unprivileged user can instruct the service to load an arbitrary kernel driver (SYS file) via a custom INF file, bypassing signature checks and GUI-based privilege restrictions. The exploit is implemented in C++ and consists of a Visual Studio project with supporting files for MD5 hashing, hexdump output, and IPC message structures. The main exploit logic resides in PoC.TV.Service.IPC/Main.cpp, which handles the socket communication, authentication spoofing, and driver installation request. The README provides detailed background, usage instructions, and references to advisories and blog posts. The exploit is version-dependent and may require minor modifications to match the target TeamViewer version. No remote or network attack is possible; the attack vector is strictly local, requiring code execution on the target machine.
