CVE-2021-24084 is an information disclosure vulnerability in Windows Mobile Device Management (MDM). The vulnerability allows an attacker to gain access to sensitive information that should otherwise be protected by the operating system's security boundaries. The flaw exists in the way Windows MDM handles certain requests, potentially exposing user or system data to unauthorized parties.

This repository contains a Windows local privilege escalation exploit targeting the Fax service, as referenced in the linked 0patch blog post. The main entry point is 'WindowsMDMLPE.cpp', which orchestrates the exploit steps. The exploit abuses Windows service and registry manipulation to escalate privileges to SYSTEM. It sets up a reverse shell server (see 'ReverseShellServer.cpp') that listens on TCP port 1440 on localhost. Upon successful exploitation, the exploit launches a SYSTEM shell and connects it to the attacker's client via the local TCP socket. The codebase includes utilities for manipulating files, directories, symbolic links, and registry keys at a low level using native Windows APIs. The exploit is operational and provides a working SYSTEM shell if the target is vulnerable. No external network endpoints are used; all communication is local. The exploit is not part of a framework and is implemented in C++ with several supporting header and source files.
This repository implements a local privilege escalation (LPE) exploit for CVE-2021-24084, targeting unpatched Windows 10, Windows 11, and Windows Server systems. The exploit leverages a vulnerability in the Windows MDM (Mobile Device Management) service to escalate privileges to SYSTEM. The main entry point is 'WindowsMDM-LPE/WindowsMDMLPE.cpp', which orchestrates the attack by manipulating Windows services and registry keys, particularly the 'Fax' service. Upon successful exploitation, the code spawns a reverse shell server (implemented in 'ReverseShellServer.cpp') that listens on TCP port 1440 on localhost, allowing the attacker to execute commands as SYSTEM. The codebase is written in C++ and includes several helper classes for file, registry, and symbolic link manipulation. The exploit is operational and provides a working SYSTEM shell, but is not part of a larger exploitation framework.
