This repository is a proof-of-concept (POC) exploit for CVE-2023-28229, a local privilege escalation (EoP) and sandbox escape vulnerability in the Microsoft Windows CNG KeyIso RPC service. The exploit is implemented in C and consists of several source and header files, with the main logic in 'exp/hax.c'. The exploit works by abusing a use-after-free (UAF) condition in the KeyIso RPC service, allowing the attacker to load an arbitrary DLL (by default, 'C:\Users\User\Desktop\hax.dll') into a privileged process such as lsass.exe. The code orchestrates a race condition using multiple threads to trigger the UAF, sprays fake provider objects, and manipulates the RPC interface to achieve code execution. The repository includes the necessary IDL file ('keyiso.idl') to interact with the KeyIso RPC interface. The exploit requires local code execution on a vulnerable Windows system and does not target remote systems. The structure is typical for a Visual Studio C project, with solution and project files, and the main entry point is 'exp/hax.c'.
This repository contains a working exploit for CVE-2023-28229, a privilege escalation (EoP) and sandbox escape vulnerability in the Windows CNG KeyIso RPC service. The main exploit is implemented in C (exp/hax.c) and targets a Use-After-Free (UAF) in the KeyIso RPC interface, allowing an attacker to load an arbitrary DLL (C:\Users\User\Desktop\hax.dll) into the LSASS process, resulting in SYSTEM-level code execution. The exploit orchestrates a race condition using multiple threads and sprays fake provider objects to trigger the UAF and hijack code execution. Additionally, the repository includes a batch script (bin/build.bat) that can be used to propagate a worm across the local network by copying itself to remote hosts via SMB (using net use to connect to 192.168.1.x addresses) and establishing persistence via the Windows registry. The script also includes commands to download and execute further payloads using PowerShell from a remote URL (placeholder <URL HERE>), and disables security features such as Windows Defender and Task Manager. The codebase is structured as a Visual Studio C project with supporting IDL and header files for the KeyIso RPC interface. The exploit is operational and provides a SYSTEM shell or arbitrary code execution if successful. The batch script demonstrates weaponization potential by enabling automated lateral movement and payload delivery.
