Loading vulnerability…
CVE-2016-0040 is a local privilege escalation vulnerability in the Windows kernel (Vista SP2, Server 2008 SP2/R2 SP1, Windows 7 SP1) that allows a local attacker to gain SYSTEM privileges by exploiting the GDI bitmap object management in kernel memory. The vulnerability is exploited by manipulating the internal pointer (pvScan0) of a bitmap object through a crafted application, enabling arbitrary kernel memory read/write primitives. The exploit leverages predictable heap allocation of bitmaps and abuses GDI Manager/Worker bitmap relationships to overwrite sensitive kernel structures, such as process tokens.

This repository contains a single Metasploit module: 'modules/exploits/windows/local/ms16_014_wmi_recv_notif.rb'. The module exploits CVE-2016-0040, a privilege escalation vulnerability in the WMI subsystem of Windows 7 SP0/SP1 x64. The exploit is local and requires an existing Meterpreter session on a vulnerable system. The module checks the OS version and architecture, ensures the session is not already SYSTEM, and then reflectively injects a DLL ('CVE-2016-0040.x64.dll') containing the exploit and payload. Upon successful exploitation, arbitrary code (typically a Meterpreter shell) is executed with SYSTEM privileges. The module is operational and part of the Metasploit framework, targeting Microsoft Windows 7 x64 systems. The only fingerprintable endpoint is the DLL file used for exploitation.
This repository provides a weaponized local privilege escalation exploit for CVE-2016-0040, targeting the WMI subsystem vulnerability in Windows 7 SP0/SP1 x64. The structure includes C source code for the exploit logic (Application, Library, Metasploit directories), a Metasploit module (module.rb) for integration with the Metasploit Framework, and supporting scripts for installation and testing. The main exploit logic is implemented in C, leveraging GDI bitmap primitives to achieve kernel read/write and ultimately steal the SYSTEM process token. The Metasploit module automates exploitation by injecting a reflective DLL into a process (e.g., notepad.exe) and executing a user-supplied payload as SYSTEM. The exploit requires local access and is not a remote exploit. Key fingerprintable endpoints include the device object '\\.\WMIDataDevice' and the Windows kernel binary path. The repository is mature, providing both standalone and Metasploit-integrated exploitation paths, and is suitable for post-exploitation privilege escalation on vulnerable Windows 7 x64 systems.
